Solvent: xylene

Specific gravity: 0.89-0.93

Reflectivity: 1.477-1.497 (25 ℃)

Characteristics and use

Good compatibility with most paint systems

Low surface tension can improve the wettability of the substrate

It can prevent coating orange peel and crater

Improve the fluidity and make the film flat.

Reduce the friction coefficient of the coating film, improve the scratch resistance and increase the viscosity

It will not decompose at 150 ℃ - 200 ℃, and it has good recoating property when baked below 200 ℃
