HW-503 is a low molecular weight polyamide curing agent with high solids and low viscosity, which is formed by the condensation of multistage fatty amines and fatty acids, with good flow performance, fast curing speed, long pot life. It has good paint film after curing with epoxy resin,Good adhesion, excellent flexibility, excellent water and solvent resistance. Suitable for epoxy system coating Materials, industrial anti-corrosive primers, Marine paints, adhesives, sealants, electrical potting, coatings, flooring and high grade coatings.
