German technical background VOK-031 Defoamer Good yellowing resistance to ultraviolet radiation replaces BYK-031

German technical background VOK ®- DF 031 Defoamer

Mineral oil defoamer for defoaming emulsion paint, lotion plaster and lotion adhesive during their production and application. This defoamer is stable in storage, resistant to ultraviolet radiation yellowing, and will not affect the color acceptance and color rendering in the coloring system.

VOK ®- DF 031 contains no organic silicon and is used in high filled emulsion paint with pigment volume concentration of 50-85%. In order to make good addition, it is necessary to have a fairly high shear force. VOK is recommended for new recipes ®- DF 032 replaces VOK ®- DF 031, because it is easy to join.
