Warning

1. Solvents, pigments, or extenders, etc. used should be free from compounds containing active hydrogen groups such as water, alcohols, or amines. It is recommended to use “urethane grade” solvents for the dilution (with water content below 500 ppm) , and ≥25% solids content after diluted is recommended.

2. The roduct is sensitive to moisture and should be kept in its original container or in a volume tank under dry nitrogen blanketing, for example.

3. Appropriate storage for 6 months does not normally affect the product in any way if it is stored in its sealed original drums in proper storage conditions at temperatures below 40°C.
