SPI 8089 is a modified cycloaliphatic amine that provides fast cure at low temperatures and excellent performance in wet and damp conditions. SPI 8089 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. 8089 cured coatings provide good resistance to water, acid, and solvents and can also be used as an accelerator for other aliphatic and cycloaliphatic hardeners.

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 8055L is an amidoamine curing agent representing the lowest imidazoline content in it class. SPI 8055L provides faster reactivity with liquid and solid epoxy resins. SPI 8055L is recommended for high solids coatings, adhesives, trowleable flooring and concrete patching compounds. Typical of amidoamines, SPI 8055L provides superior adhesion and corrosion resistance.
