Excellent Heat Resistance

PUD Heat resistance

Polyurethane dispersions have good heat resistance as supplied but it can be improved to meet rigorous high temperature application requirements through the use of polyisocyanate crosslinkers. The systems cure at room temperature over a period of a few days to achieve superior final performance.

You can witness the difference between the one- and two-component systems for Products A & B in Figure 1 below:
