YL-GB9200 can be diluted with esters, ether esters, ketones and other solvents. Compatibility and stability with diluted solutions should always be tested.


YL-GB9200 is a curing agent component suitable for one component polyurethane baking paint. It can also be added to the traditional system as an additive, which helps to improve the flexibility and adhesion of the film.

The crosslinking effect of YL-GB9200 is affected by the baking temperature and the type of co-reactants. The recommended baking temperature is 150 ~ 170 ℃. With the increase of baking temperature, the baking time decreases correspondingly. Adding catalyst DBTL can significantly reduce the baking temperature, and the storage stability is not affected.

With the influence of baking time and type of CO reactants, yellowing of paint film may occur at baking temperature above 160 ℃.
