Vinyl Acetate/Crotonic Acid Copolymer
The carboxylated VINNAPAS® C series, when paired with magnesium oxide or calcium oxide, provides a perfect thickening system for unsaturated resin composites. Used in combination with thickeners, the carboxylated VINNAPAS® C series allows for stable, high viscosity levels. After maturation, this combination is ideal for preventing thermoplastic resin exudation.
