Composition: polymer, without silicone

Appearance: clarified liquid

Nonvolatile: 10.0-11.5%

Solvent: aromatic hydrocarbon solvent

Specific gravity: about 0.87

Refractive index: 1.496-1.506 (25 ℃)

Characteristics and use

In solvent-free or high-viscosity systems, the air mixed by mechanical forces is often difficult to remove, and the general polysiloxane defoamer has no obvious effect in this regard

Non-silicone polymer with special interface properties can inhibit the bubbles generated by air mixing at the initial stage, and help the escape and rupture of bubbles, so as to obtain a uniform and flat surface

It can play an excellent role in foam inhibition and defoaming in solvent-based or solvent-free epoxy resin systems

It is suitable for the defoaming of UV-curable coatings, fiberglass, glass fiber reinforced sheet molded plastics, bulk molded plastics, and rubber shell coatings. It can reduce the occurrence of voids and make the molded products have higher strength and flatness

It has good compatibility and is suitable for transparent coating system

Scope of application

Epoxy coating

Unsaturated polyester coating

UV coating
