Storage stability Store
in a cool, dry place in the original unopened packaging for 36 months. Products beyond the storage period can be used after passing the inspection. Before the container is completely used, it must be tightly closed immediately after use.

Recommended formula
PU varnish recommended formula

Remarks:
1. NCO% of N3390 = 19.6, produced by Germany Covestro.
2. After the A and B components are mixed, the storage period is 5-7 hours under the condition of a cover. Therefore, the mixed materials should be used as soon as possible, otherwise the materials will gel and cannot be used.
3. Recommended baking conditions
Coatings for car clothing film: After baking at 100-130 ° C for 2-3 minutes, cool and roll, and continue to mature at 60-80 ° C. The higher the temperature, the longer the time and the better the effect.

Note: The quality of stain resistance and chemical resistance depends on whether the coating is fully cross-linked; it is effective to put the surface-treated film into the curing box for curing. The maturation time needs at least 24 hours, if it can reach more than 48 hours, the effect is better. Other industrial coatings: 1 hour at 80 ℃ or 5 minutes at 150 ℃, easy to clean.
