CH-940 paint film have excellent hardness, tensile sex, flexibility, chemical resistance and high gloss. By joining CH-100 multi-function crosslinking agent into  CH-940, it could be achieve the most excellent resistance to alcohol performance. 
Characteristics:
1. Free isocyanate root is zero, non-toxic pure environmental protection, without other benzene and other harmful solvents, no harm to human body, VOC contents confirms to the international environmental protection standard.

3. It feels smooth and fine, good and clear luster.
4. High hardness, pencil rigidity scratches can reach 1 H 
5. Water resistant, fine chemicals.
