SPI 8125 is a moderate to high viscosity polyamide hardener, which imparts resiliency, and toughness to a cured epoxy formulation. Its imidazoline content provides improved compatibility with epoxy resins. One to one by volume mix ratios are possible with SPI 7128 standard liquid epoxy resin, and this makes this hardener a good choice for two part adhesive applications.

SPI 8141 is a low viscosity room temperature polyamide curing agent, which imparts resiliency and toughness to a cured epoxy system. Its high imidazoline content provides for better compatibility and lower viscosity than other standard polyamide hardeners. SPI 8141 epoxy blends will cure at temperatures of 50F and above.

SPI 8205U is a highly accelerated aliphatic amine curing agent allowing for rapid and low temperature cure 100% solids epoxy systems. It also may be used as an accelerator for other amine-based curing systems.

SPI 8055 is an industry standard grade of amidoamine curing agent. SPI 8055 provides moderate pot life, and cure response with liquid and solid epoxy solutions, and is user friendly for most applications requiring amidoamine advantages. Typical of amidoamines, SPI 8055 provides superior adhesion and corrosion resistance.

SPI 8085 is a modified cycloaliphatic amine. SPI 8085 provides fast cure at low temperatures and excellent performance in wet and damp conditions. SPI 8085 is low in viscosity, and has excellent early blush resistance. It can be used as a sole curing system or as an accelerator for other amine curing agent systems. 8085 cured coatings provide good resistance to water, acid, and solvents.

SPI 2071 is a phenol free Mannich base aliphatic amine epoxy curing agent. SPI 2071 will develop properties rapidly at low temperatures. SPI 2071 has a longer working life than other similarly accelerated amines. This unique blend of properties is ideal for floor coatings and other chemically resistant coatings.
