OSi SiFOC 307 Polyether Modified Silicon Leveling Agent

Product Description

Chemical Name: OSi SiFOC 307 Polyether Modified Silicon Leveling Agent

Properties

● Good compatibility with varnish.

● Provide a stronger reduction of the surface tension.

● Reduce the friction coefficient. Increase slip and improve scratch resistance.

● Good recoating and minimal influence on adhesion of coating films at suitable addition and baking temperature.

● Excellent property of anti-crater. Commonly used to replace oil-resistant agents, do not affect the environment and recoatability.

● Not suited for water-based.

● Hazy and viscous may occur at low temperatures. It would become clear and flow after being heated. This will not influence the quality.

Incorporation

Added with a suitable solvent. Can add in any stage during the production including post-addition.
