Performance features :

Dissolved in petroleum hydrocarbons, aromatic, esters, ketones, gasoline, benzene, ethyl acetate, acetone and turpentine and other solvents, do not dissolved in water and ethanol. The materials have the advantage of light-color, low odor, oxidation resistance, thermal stability, strong adhesion, can forming transparent system with NR, CR, SBR, EVA, SIS and SBS polymers in a large proportion scope.

 

Uses:

1, used in EVA, SBS and SIS hot melt adhesive, and pressure-sensitive adhesive, SBR rubber, natural rubber and SBR rubber, natural rubber, acrylic-based adhesive, also can be used in paint.

2, with vegetable oil through refining thermal polymerization can be used in ester gum, Phenolic painted ;in polyester, Nitro or Paint Polyaminobenzonitrile can be improved the coating hardness, brightness, grinders and fullness.It is play stick and link agent role in road  Paint.
