Resyn 1190 is a carboxylated vinyl acetate/crotonic acid copolymer supplied as a free-flowing white powder for alcohol-based film formation in personal care applications. The batch certificate reports acid value, loss on drying, and residual monomer; the acid value controls neutralizer stoichiometry because acid value drift of ±5 mg KOH/g shifts AMP-95 demand by approximately 0.04 g per 100 g of a 5 wt% active solution. The unneutralized polymer dissolves in anhydrous ethanol and isopropanol but is water-insoluble. Water dispersibility is developed only after 60–100% neutralization with an amino alcohol or alkali. Neutralization is exothermic, and batch cooling at 20–25 °C is required to limit ester hydrolysis and viscosity drift. The material should not be reverse-charged; adding ethanol to the powder forms agglomerates that are difficult to disperse without high shear.
In anhydrous ethanol aerosol hair sprays, Resyn 1190 is metered at 2.5–5.0 wt% solids as the primary fixative polymer. The mixing vessel is a jacketed stainless steel tank with counter-rotating anchor agitation at 20–40 rpm and a bottom-mounted rotor-stator circulator. Ethanol is charged first, and the resin is fed through a screened hopper at approximately 5–8 kg/min per 1,000 L batch while the circulator runs at 1,500–2,500 rpm. The batch temperature is held at 20–25 °C. After complete dissolution, AMP-95 is charged at a level calculated to achieve 90–100% neutralization of the batch-specific acid value. Under-neutralization leaves unneutralized carboxyl groups that are solvent-sensitive and deposit as visible particles on hair at high humidity. Over-neutralization above pH 8.5 accelerates ester hydrolysis during warehousing; 12-week storage at 40 °C may show pH drift greater than 0.3 units and loss of hard-hold performance on hair tresses.
| Neutralization degree | AMP-95 charge (g/100 g solution) | pH in 50/50 ethanol/water | Water tolerance (mL water/10 g solution) | 120-min curl retention at 27 °C/90% RH (%) |
|---|---|---|---|---|
| 0% | 0 | 4.2 | <1 | Not evaluated |
| 50% | 0.48 | 5.8 | 4 | 42 |
| 70% | 0.67 | 6.4 | 18 | 58 |
| 90% | 0.86 | 7.0 | >30 | 74 |
| 100% | 0.95 | 7.6 | >50 | 81 |

After neutralization, silicone copolyol at 0.05–0.15 wt%, fragrance, and corrosion inhibitor are mixed for 15 min. The solution is filtered through a 10 µm membrane and transferred to a nitrogen-blanketed storage tank. Tinplate aerosol cans with epoxy-phenolic linings are used. Valve mounting includes a 0.018 inch mechanical break-up actuator and a 0.020 inch capillary dip tube. Propellant A-46 is pressure-gassed through the valve at 30–40 wt% of total fill. Final can pressure at 21 °C is 45–50 psig. Spray pattern is checked with laser diffraction; maldistribution is corrected by changing actuator insert or propellant ratio rather than increasing resin solids. VOC content is determined by EPA Method 24 and reported under 40 CFR Part 59. Finished cans are classified as flammable aerosols and labeled accordingly.
Water addition to Resyn 1190 solutions is sequence-dependent. If deionized water is added before neutralization, the unneutralized acid copolymer precipitates as a white coagulum and post-shear cannot restore clarity. In production pump spray batches, the neutralized ethanol concentrate is prepared first, then deionized water is metered in at 60–70 kg/min through a sparging nozzle while the mixer runs at 400–600 rpm. Typical formula ranges are 3.5–5.0 wt% Resyn 1190, 0.35–0.55 wt% AMP-95, 30–45 wt% ethanol, 15–30 wt% deionized water, 1–3 wt% propylene glycol, and 0.1–0.3 wt% non-ionic surfactant. The final pH is adjusted to 7.0–7.5 before water makes up the remainder. Water content above 45 wt% causes carboxylated resin association, measurable viscosity loss, and increased filtration pressure across a 10 µm polypropylene membrane.
The terminal product is a low-VOC or water-compatible pump styling spray filled into high-density polyethylene bottles with dip-tube pumps delivering 0.14–0.18 g per stroke. Batch viscosity is measured on a Brookfield viscometer at 25 °C using spindle 1 at 60 rpm; values typically fall between 15–40 mPa·s. High-humidity curl retention is evaluated on prewashed hair tresses at 27 °C and 90% RH over 120 min. The film must remain transparent after drying at 20 °C and 50% RH for 4 h. If haze appears, the neutralization degree is checked before ester hydrolysis is suspected. Preservative selection must avoid strong anionic buffers that could strip the amine neutralizer and reduce water tolerance.
Styling mousse manufacture is run as a two-phase emulsion before propellant gassing. The ethanol/water phase contains 2.0–3.0 wt% Resyn 1190 neutralized with AMP-95 to pH 6.8–7.2. The oil phase includes 0.8–1.5 wt% ceteareth-20, 0.2–0.5 wt% cetyl alcohol, and 0.1–0.3 wt% dimethicone. Both phases are heated to 60–65 °C and combined under a high-shear homogenizer at 3,000 rpm for 5–8 min. Cooling to 20–25 °C occurs under anchor agitation at 20 rpm. The bulk is filled into epoxy-phenolic lined tinplate cans with a foam valve having a 0.016 inch stem orifice and a 0.020 inch dip tube. A-46 propellant is charged at 8–10 wt% of total fill. Can pressure at 21 °C is 45–50 psig. Foam density is measured by weighing a fixed-volume cylindrical collector and is adjusted to 0.10–0.15 g/cm³. Cationic conditioning polymers must be excluded; quaternized ammonium compounds complex with the carboxyl groups and produce visible flocculation. Non-ionic or amphoteric modifiers are used instead.
In water-based styling gels, Resyn 1190 does not swell directly in cold water. It is either pre-dissolved in ethanol and then let down into water, or it is dispersed in warm water after neutralizer addition. A production-scale formula uses 5.0–7.0 wt% Resyn 1190, 0.6–0.9 wt% AMP-95, 10–20 wt% ethanol, 3–5 wt% propylene glycol, and deionized water to 100 wt%. The mixer is a scraped-wall vessel with a top-entering agitator running at 500–800 rpm; vortex depth must not exceed one-third of batch height. When a carbomer is used as a co-thickener at 0.2–0.4 wt%, it is hydrated separately, neutralized with AMP-95, and then blended with the Resyn 1190 solution. Reverse addition produces localized bridging and lumps that cannot be passed through the 10 µm finishing filter.
Finished gel viscosity is measured on a Brookfield RVT viscometer using spindle 6 at 10 rpm; acceptable ranges are 15,000–30,000 mPa·s. pH is held between 7.0–7.5. Below pH 6.8 the film becomes water-resistant and difficult to wash out; above pH 8.0 ester hydrolysis reduces shear stability. The product is cold-filled into jars or tubes. A 30-day stability screen at 25 °C, 4 °C, and 45 °C should include visual clarity, pH, and viscosity retention. If viscosity drops more than 20% at 45 °C, the acrylic thickener phase is checked before the carboxylated resin is blamed.
Temporary hair color systems based on direct film casting use Resyn 1190 as the fixative phase around dispersed pigments and metallic pigments. The polymer is dissolved in anhydrous ethanol at 4.0–6.0 wt% with AMP-95 neutralization not exceeding 70% to maintain film integrity on exposure to water. Pigment is dispersed separately with a polyhydroxystearate dispersant at 1.5 times pigment weight and ground in a bead mill to Hegman 6.5. The mill base is let down under low-shear agitation at 200–300 rpm. The final ethanol content is 60–80 wt%, and butylene glycol is used at 2–4 wt% to slow evaporation. The sprayable edge-control version is filled into pump dispensers; the gel version is packed into airless tubes. Film transfer resistance is checked by pressing a dry white cotton cloth under 9.8 N/cm² for 30 s after the film has dried at 25 °C and 50% RH for 2 h. Published data for this specific pigment/film former configuration is limited, so mill base compatibility must be confirmed on the production batch before scale-up.
Colorant compliance follows the destination-market positive list. For the European Union, colorants must be listed in Annex IV of Regulation (EC) No 1223/2009. For the United States, cosmetic color additives are restricted under 21 CFR Part 73 and 21 CFR Part 74. High-humidity transfer testing is run at 27 °C and 90% RH for 4 h. The formula must not rely on resin hardness alone; pigment loading, dispersant level, and neutralization degree together control crocking resistance. Over-neutralization in this application creates a water-sensitive film that streaks during wear. Under-neutralization leaves the film too solvent-sensitive and reduces pigment adhesion to the hair shaft.

Resyn 1190 is supplied as a suspension-polymerised poly(vinyl chloride) homopolymer resin. The powder is intended for conversion in dry blends rather than as a paste-grade or emulsion-grade feedstock, and the supplier’s certificate of analysis reports lot-level properties by ASTM D1755-15 cell classification, viscosity number by ISO 1628-2, apparent bulk density by ISO 60, and sieve residue by ISO 4610. Because the numerical classification of a given lot can shift within the production campaign, the processor should compare the certificate of analysis against the permitted tolerance for the specific pipe, profile, sheet, or moulding formulation before dry blending. The grade is positioned for balanced melt viscosity, gelation behaviour, and impact retention in continuous extrusion and calendering. Production data from counter-rotating twin-screw lines with 36:1 L/D barrels indicate that dry-blend temperature, particle porosity, and stabiliser distribution exert a greater influence on batch consistency than small changes in molecular weight within the same cell class.
Laboratory fusion behaviour is assessed in a torque rheometer according to ASTM D2538-18, using a heated mixing bowl and calibrated rotor speed. The resulting torque trace records a loading peak, a fusion peak, and an equilibrium torque plateau. Fusion time is a function of external lubricants, stabiliser type, filler volume, and the resin particle porosity rather than a single resin property. Dry blends based on Resyn 1190 typically show a distinguishable fusion shoulder when the bowl temperature is maintained at a temperature above the crystalline melt transition of the compound; exact torque values depend on formulation and cannot be read from a single resin datasheet.
The critical processing threshold in high-output extrusion is not the absolute torque value but the width of the stable torque plateau. As melt temperature approaches 205 °C, the equilibrium torque declines, but residual thermal stability narrows and the risk of plate-out increases. When melt temperature falls below the full gelation range, the compound may carry partially fused primary particles into the die, lowering tensile strength and producing rough surfaces. The stable operating band is frequently narrower than ±5 °C around the target melt temperature in high-speed pipe extrusion.
Published data for this specific configuration is limited when the customer has not generated baseline torque curves on the actual production machine. Validated comparison should therefore be made against an internal reference compound on the same rotor geometry, not against generic literature values.
Extrusion of thick-walled industrial pipe from Resyn 1190 dry blends is commonly carried out on counter-rotating twin-screw extruders with vented barrel sections. Feed throat temperatures are held below 65 °C to prevent premature agglomeration. Barrel zone settings are typically selected to produce a melt temperature of 190 °C to 195 °C at the adapter, with die zones raised only enough to maintain surface gloss without exceeding the stabiliser-limited upper boundary. Dimensional conformity is checked against ISO 3126 and impact resistance against ISO 3127. The principal bottleneck in this application is not melt pumping but the rapid surface chilling in the sizing vacuum; a skin that solidifies before crystallinity fully develops yields low gelation and reduced impact strength. Resyn 1190’s medium-K suspension architecture generally permits lower stabiliser demand than high-K pressure-pipe grades, but the formulation must still retain enough internal lubricant to limit frictional heating in the feed and metering zones.
Particle porosity controls the rate of plasticiser uptake, dry-blend friability, and the distribution of liquid stabilisers and lubricants across the resin surface and internal void network. Suspension-polymerised vinyl chloride homopolymers of the Resyn 1190 class are produced with a controlled grain and primary-particle structure; this structure differs from emulsion paste resins, which have much finer particle size and much higher specific surface area. The lower surface area of suspension resin particles reduces the quantity of liquid additive that can be adsorbed without increasing dry-blend build-up on mixer walls.

Compared with high-K grades used for pressure pipe and thick sheet, Resyn 1190 would be expected to process with lower equilibrium torque and lower melt viscosity while retaining sufficient toughness for many building and infrastructure profiles. Compared with low-K injection-moulding grades, it produces higher melt viscosity and can require higher melt temperature to fill thin-wall cavities, but the notched impact strength and long-term ductility are generally more favourable. Where the end-use specification requires the very high creep resistance of a high-K resin, Resyn 1190 should not be substituted without a full ISO 9080 hydrostatic strength assessment if the part is pressurised.
If the melt temperature on a twin-screw extruder is allowed to exceed 205 °C, degradation accelerates rapidly because hydrochloric acid evolution catalyses further dehydrochlorination. The conductometric method of ISO 182-3 provides a quantitative measure of the residual stability margin, but the value is meaningful only when the test is run on the complete compound, not on the unpigmented resin. On production lines, early acid generation appears as die-lip plate-out, dark specks, and a progressive shift toward yellow in unpigmented formulations. The time to visible failure is influenced by hold-up volume in the die, screw residence time distribution, and the presence of iron or copper contaminants from wear surfaces.
At the other boundary, incomplete fusion leads to a rough surface and low mechanical strength. The appearance of unfused primary particles under a transmitted-light microscope indicates that the melt temperature or residence time is too low for the gelation of this suspension resin. In rigid formulations, the gelation degree is commonly inferred from solvent extraction or from a torque trace rather than from visual inspection alone. The stable process window is therefore bounded by gelation on the low-temperature side and degradation on the high-temperature side, and the two boundaries can move closer together when high filler loadings raise internal shear heating.
Direct powder injection moulding of fittings from Resyn 1190 is possible but less common than extrusion. In a reciprocating screw, the plasticating unit should use a compression ratio of 2.0:1 to 2.5:1 and a check-ring clearance not exceeding 0.05 mm to avoid material hang-up. Test specimens are moulded according to ISO 294-1:2017 and tested under ASTM D638-14. Because the resin is a medium-K suspension homopolymer, melt residence time must be limited; long hold-up at high back pressure produces localised burning and black specks. Injection pressure and clamp force requirements are similar to rigid PVC compounds of the same K-value class.
In rigid and filled formulations, the thermal stabiliser is concentrated in the primary particle boundaries and must migrate into the polymer phase during gelation. When the plasticizer level is low, stabiliser migration may be slower than the rate of thermal stress, particularly under high shear. On a two-roll mill, early discolouration can appear within minutes of a stoppage if the compound is left heated on the rolls. The precise time depends on stabiliser chemistry, filler type, and roll temperature; no universal value can be assigned to the resin alone. However, plant trials should separate the contribution of the resin from that of the stabiliser system by comparing Resyn 1190 against an internal control resin at the same stabiliser and lubricant levels.
Calcium-zinc stabiliser systems at addition levels below 2.5 phr may provide sufficient early colour in thin-wall profile extrusion but leave a narrow margin during extended start-ups. Organotin stabilisers generally provide longer residual stability but require different lubricant balancing because of their effect on gelation and plate-out behaviour. Published data for this specific configuration is limited where the customer’s stabiliser formulation has not been optimised for medium-K suspension PVC.
Calendering of flexible and semi-rigid sheet with Resyn 1190 uses four-roll inverted-L or L-type calenders. Friction ratios between rolls are maintained to keep a rolling bank of 10 mm to 20 mm; a bank that is too small causes pin lines, while an oversized bank traps air and creates gel defects. Moisture on the resin surface can produce splay in thin film, so opened bags stored above 70% relative humidity should be pre-dried at 50 °C to 60 °C before calendering. The grade should not be combined with amine-based additives, which promote premature dehydrochlorination and colour shift. Acidic fillers that consume the stabiliser must be avoided unless the stabiliser addition is adjusted and the residual stability is confirmed by ISO 182-3 on the finished compound.
