YL-GB9300 can be diluted with esters, ether esters, ketones and other solvents. Compatibility and stability with diluted solutions should always be tested.


YL-GB9300 is a curing agent suitable for one component polyurethane baking paint, which can improve the hardness, impact strength, adhesion and chemical resistance of the paint film; it can also be used in the field of textile and printing glue, which helps to improve the fastness, scrubbing resistance, chemical resistance and weather resistance of the coating.

The crosslinking effect of YL-GB9300 is affected by the baking temperature and the type of co-reactants. The recommended baking temperature is 110 ~ 130 ℃. With the increase of baking temperature, the baking time decreases correspondingly; YL-GB9300 has the property of heat resistance yellowing, but it may produce slight yellowing with the influence of baking temperature and type of co-reactants.
