Handling

CURING AGENT W4 P DIL must be added just before application and stirred till complete homogeneity. Reaction starts immediately, so we recommend to use the product just after activation. The crosslinking mechanism depends on different aspects such as adhesive concentration, amount of crosslinker, temperature. We suggest to check the curing conditions in advance, in order to avoid to spoil material.

Packaging

The product is supplied in iron drums (60 kg); iron drums (200 kg).

Storing

Polyisocyanates are very sensitive to moisture. Reaction with water or moisture can form solid insoluble polyureas, which can block pipes, valves, etc. CURING AGENT W4 P DIL must be stored in well sealed original plastic drums or aluminum/glass bottles, at temperatures between 10°C and 30°C. At higher temperatures it can develop hazardous vapors.

Use within 6 months from production date (unopened and in the original packaging).
