BYK-Chemie GmbH (Wesel, Germany) introduced at JEC Europe 2013 another new green additive — BYK-S 760 styrene-emission reducer for unsaturated polyester and vinyl ester resins. It comprises a combination of waxes with polar components (more than 85 percent renewable raw material content). The company reports that it is highly effective in reducing the monostyrene emissions typical of all types of polyesters and vinyl esters. The additive’s emissions reduction, however, is said to have no negative influence on interlaminar adhesion. More than 70 percent of its ingredients contain unsaturated groups, which are said to react with the resin during polymerization. It is recommended at levels of 0.3 to 1.0 percent.
