Product advantages:
This product is an excellent curing agent of alicyclic amine (modified) epoxy resin, especially suitable for high humidity and low temperature environment. The product shows high hardness, deflection temperature under load, good color stability (yellowing resistance) and chemical resistance. The curing material is light, the thermal deformation temperature is high, and the comprehensive mechanical properties are superior (high strength and good toughness); Excellent weather resistance and moisture and heat aging resistance; Excellent adhesion and high surface gloss of cured product.
