Epoxy hardener 8125 is a low viscosity aliphatic amine hardener suitable to cure at ambient temperature. It has high etching power and therefore has high adhesion to a variety of low surface-energy substrates including coated metallic substrates. When systems based on this are fully cured, they possess excellent high mechanical strength. Features A high degree of chemical resistance Rapid room temperature cure Low viscosity Low color High heat distortion temperatures 1. The
