Polyamide hardeners china The pot life of the emulsified epoxy resin system is short, the cured coating film has the disadvantages of poor flexibility, poor impact performance, and brittle coating film, and the performance of the modified polyamide curing agent is still not ideal , Therefore, the curing agent used in the water-based epoxy system is mainly polyamine-epoxy adduct.

Polyamide hardeners china

Polyamide hardeners china is a widely used epoxy curing agent, mainly formed by the polycondensation reaction of dimer acid and polyamine, the reactive primary and secondary amines Polyamide hardeners china and bisphenol A epoxy resin in the molecular chain The reaction is carried out at room temperature or lower than room temperature, and the reaction is moderately heat-resistant. It cures slowly and has a long pot life.

Polyamide hardeners china has a large carbon and hydrogen content in the molecular chain, and the cured epoxy is a highly plasticized rigid thermosetting polymer. This polymer is characterized by high tensile strength, compressive strength, and high flexural strength, but it is relatively rigid and has excellent impact resistance.
