National Paint Polyurethane Hardener – Part B is a specially formulated curing component used in two-pack polyurethane coating systems. When mixed with the compatible polyurethane base (Part A), it activates the chemical reaction required to produce a strong, durable, and long-lasting finish.

This polyurethane hardener significantly improves the coating’s mechanical strength, adhesion, gloss retention, and resistance to chemicals, abrasion, and weather conditions. It is ideal for use in industrial, automotive, marine, and architectural applications, where superior performance and protection are required.
