Silicone Leveling Agent and Silicone Defoamer

Catalyst and Auxiliary

Composition：
Organic modified silicone

Typical properties：
Appearance：amber-colored clear liquid.
Active matter content：100％.
Refractive index at 25ºC：1.445-1.455.

Special properties：
Silicone defoamer to prevent foam and bubble formation arising during paint production and application in non-polar to high polarity solvent-based systems. Silibase-2820 Silicone Leveling Agent and Silicone Defoamer improves the surface properties of coatings, with particular emphasis upon levelling, increases surface slip and thus improves scratch and mar resistance. Formation of Bénard cells is prevented and orientation of flatting agents is improved.

Silibase-2820 Silicone Leveling Agent and Silicone Defoamer does not cause dewetting or defects in intercoat adhesion when recoated.

industrial coatings: 0.05 - 0.3 %
decorative coatings: 0.05 - 0.3 %
Predilution in a suitable solvent simplifies dosage and incorporation.
