High Solids Low Viscosity Polyamide Epoxy Resin HW-503 Polyamide Curing Agent
High solids and low viscosity polyamide curing agent HW-503 suitable for coal tar epoxy system coating materials
Polyamide Epoxy Resin 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 coal tar epoxy system coating Materials, industrial anti-corrosive primers, Marine paints, adhesives, sealants, electrical potting, coatings, flooring and high grade coatings.
Performance:
Low viscosity, good flow performance and long operation time
Excellent corrosion resistance, solvent resistance and salt spray resistance
Good flexibility and strong adhesion
The formula proportion can be adjusted with a flexible range
