Block-type copolymer of styrene, butyl acrylate and vinyl acetate. Acts as a polymeric processing aid and adhesion promoter. Constitutes new class of block-type PVAc-copolymers and at the same time low profile additives, specifically designed for low and room-temperature composite processes. Provides shrinkage compensation. Improves surface quality and smoothness. Reduces deformation and tension in polyester-resin components. Offers good mechanical properties and enhanced adhesion to many substrates, such as paper, cardboard, wood, leather, glass, metal and plastic. Posses low solution viscosity and hence ideal for vacuum infusion and RTM processes. Recommended for bulk molding compound, pultrusion, resin transfer molding and sheet molding compound. Compatible with unsaturated polyesters, dicyclopentadiene (DCPD) resins and vinyl ester resins. Copolymer of vinyl acetate and crotonic acid. Acts as a polymeric processing aid and an adhesion promoter. Allows easier processing or easier incorporation of difficult fillers and additives. Significantly lowers formulation viscosity. Provides shrinkage compensation. Improves surface quality and smoothness. Reduces deformation and tension in polyester-resin components. Offers good mechanical properties and enhanced adhesion to many substrates, such as paper, cardboard, wood, leather, glass, metal and plastic. Recommended for bulk molding compound, pultrusion, resin transfer molding and sheet molding compound. Compatible with unsaturated polyesters and polystyrenes.
