- Product Highlights
Reactive Polyamides have been the workhorse of Epoxy Coating Industry for many years. Polyamide resins are high molecular-weight polymers which feature amide linkages along with the molecular chain.
Polyamide resin, which has been widely used as a curing agent for epoxy resin, is formed by the condensation reaction between dimerised fatty acid with polyamines. Molecular weights are controlled by using monobasic fatty acid as a chain terminator. Polyamides contain reactive primary and secondary amines in its molecules
Polyamides are versatile curing agents for epoxies. They are compatible with many epoxy resins, and their mixing ratio with the resins is not critical. Fairly long pot life is possible using polyamides and one can get casting with good impact strength as well as excellent adhesion to different substrates. Some polyamides are used as flexibilizers as well as a curing agent.
Polyamide Adducts provide good compatibility and better cure under adverse conditions
