It is used in coatings and printing inks. Silicone surface additive to provide good substrate wetting of critical substrates and good anti-crater performance by reduction of surface tension of the coatings. It also increases surface slip along with scratch resistance and anti-blocking. BYK®-310 is a heat resistant silicone additive, i.e., in contrast to conventional (polyether modified) silicones, it shows no thermal decomposition at temperatures between 150 °C / 300 °F and 230 °C / 450 °F. Thus, upon recoating baking systems, no loss in adhesion and no surface defects occur. (Note: The aforementioned defects can be caused by the decomposition products of conventional silicones at temperatures above 150 °C / 300 °F.) The effective substance of BYK®-310 is listed in title CFR 21 (food and drugs) § 175.300 - Indirect Food Additives, Adhesives and Components of Coatings. The usage level may not exceed 0.1% (delivery form based on total formulation) and the film thickness may not exceed 12 µm (0.5 mil.). Solution of a polyester modified poly-dimethyl-siloxane. Used in coatings and printing inks. Provides strong reduction of surface tension. Provides improved substrate wetting. Avoids cratering. Increases surface slip and gloss. Possesses increased scratch resistance and anti-blockin.g
