YL-GB9200A is a curing agent component suitable for single-component polyurethane

baking paint, and can also be added to the traditional system as an additive to help improve

the flexibility and adhesion of the paint film

The crosslinking effect of YL-GB9200A is affected by the baking temperature and the type of

coreactant, the recommended baking temperature is 150~170℃, and the baking time is

reduced accordingly with the increase of baking temperature, adding catalyst DBTL can

significantly reduce the baking temperature, and the storage stability is not affected A loud

response. With the influence of baking time and coreactant type, the paint film may develop

yellowing at baking temperatures above 160 ° C
