Application & handling
Mix A:B = 2:1 by weight. Allow the mixture to stand for 2 hours before applying. Use within 5 hours at 23±2°C and RH≤70%.
Preheat parts at 60°C for 30 minutes, coat immediately, cure at 180–220°C for 15 minutes, then cool with the oven. Control each coat’s thickness and validate coverage on your actual parts.
Confirm current grade-specific technical and safety data, and validate performance on your actual parts before production.
