Characteristics :

CORONATE HXR, HXLV, HX or HK are non-yellowingcuring agents for polyurethane coatings with better properties than diurethane condensate urethane adducts. CORONATE HXR, HXLV, HX or HK are widely used in motorcycle parts, automobile refinishing and wood coatings because of their good heat resistance and good compatibility with polyols and solvents.

Storage and Transportation:

STORAGE: It is recommended to store in a dry and cool area withproper ventilation.

Packaging:
