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.
