Curatives

Product SeriesThe HMDI/Ethers series includes aliphatic isocyanate–terminated polyether prepolymers (e.g., Pre-Pol® PC 70-90 and PC 70-70D) designed for high-performance elastomers. These systems cure rapidly (especially with Ethacure 100) to deliver high Shore A hardness, excellent UV resistance, and outstanding clarity—ideal for durable, color-stable parts.

HMDI / Ethers

Product SeriesThe MDI–Esters series includes tough, abrasion- and solvent-resistant cast urethane elastomers based on MDI polyester prepolymers. These systems cover a wide hardness range (60A–95A) and are suited for demanding applications such as squeegees, wheels, hammers, and FDA dry or wet food contact products.

MDI – Esters

Product SeriesThe PC Series offers a range of two-component, room-temperature castable urethane elastomer systems that span softness to firmness (40A to 75D) and can be hand-mixed or machine-processed without requiring post‑cure heat, enabling faster, simpler molding and casting workflows.

PC Series

Product SeriesThe PCCNO Series features solid-cast, room-temperature two-component urethane systems with medium-to-high Shore D hardness (60–80 D), formulated for low exotherm and fast demolding (10–15 minutes) to enable efficient, high-throughput casting. The systems are available in natural (tan and white) or customizable pigment colors.

PCCNO Series

Product SeriesThe PCF Series includes a diverse family of two-component polyurethane foam systems designed for both rigid and flexible applications. With formulations spanning Class I fire-retarded rigid foams, resilient cushioning foams, microcellular load-bearing foams, and self-skinning systems, the PCF Series delivers versatility, strength, and reliability for molding, insulation, seating, and specialty applications.

PCF Series

Product SeriesThe PCNO Series delivers 100% solids, low-odor, two-component urethane systems that cure at room temperature and demold in just 5–8 minutes. Designed for ease of processing and high-performance solid casting, these formulations combine minimal exotherm with rigid Shore D hardness for fast, reliable production.

PCNO Series

Product SeriesThe Polycast A Series comprises two‑component, 100% solids Shore A elastomer systems featuring customizable gel times—well-suited for casting large parts at room temperature without the need for post-cure heating. These formulations deliver excellent tensile strength, elongation, and resilience, making them ideal for tooling, concrete stamps, and flexible yet durable molded products.

Polycast A Series

Product SeriesThe Polycast D Series includes two-component, solid-cast urethane systems designed for quick processing and high-strength rigid parts. With Shore D hardness options from 55–80, low exotherm performance, and rapid demold times (3–8 minutes), these systems enable efficient production of durable castings in both tan and white formulations.

POLYCAST D Series

Product SeriesThe Polyspray Series consists of two-component, 100% solids spray elastomer systems—polyurethane, polyurea, and hybrid formulations—designed for long-lasting protection across a wide range of substrates. With zero VOCs, excellent abrasion and chemical resistance, and Shore hardness options from 60A to 95A/70D, these coatings provide durable, seamless membranes for demanding industrial and architectural applications.

Polyspray Series

Product SeriesThe PSE Series includes 100% solids, zero-VOC spray elastomer systems designed for durable surface protection across a wide range of substrates. Available in polyurea, polyurethane, and hybrid chemistries, these coatings provide excellent resistance to abrasion, impact, chemicals, and water while forming seamless, monolithic membranes.

PSE Series

Product SeriesThe PSF Series encompasses spray-applied polyurethane foam systems designed for diverse performance needs, from rigid Class I and high-temperature formulations to flexible cushioning and packaging foams. With densities spanning 0.4 to 20 lb/ft³ and specialized chemistries (rigid, flexible, microcellular), the series delivers reliable insulation, void filling, cushioning, and protective applications.

PSF Series

Product SeriesThe Specialty series centers on PC 73‑60, a TDI-based polycaprolactone elastomer available at ~60A (MOCA cure) or ~70A (E300 cure). It surpasses traditional TDI/ester systems in tensile and tear strength, making it perfect for rugged cast components requiring enhanced mechanical durability.

Speciality

Product SeriesThe TDI/Esters series includes a range of two-component hot-cast urethane prepolymers (PC 50-71 PC 50-70, PC 50-80, PC 50-85, PC 50-90, PC 55-50D, PC 55-60D, PC 50-57, PC 51-60, PC 52-60) designed for industrial and general-purpose elastomer applications. With hardness options from soft (60A and below) to rigid (50D–60D), these systems provide excellent tear strength, solvent resistance, and durometer stability, making them a trusted choice for industrial rolls, molded parts, and specialty elastomers.

TDI / Esters

Product SeriesThe TDI/Ethers series features hot-cast urethane prepolymers based on TDI/ether chemistry, offering excellent resilience, abrasion resistance, and dynamic properties. With Shore hardnesses ranging from 85A to 75D, these elastomers are well-suited for mining, wheels, custom molding, and other heavy-duty industrial uses.

TDI / Ethers
