German technical background VOK ®- Disper W920 Wetting Dispersant

Wetting dispersant for unsaturated polyester resin

VOK ®- Disper W920 is used to wet and disperse the most common and extensive fillers in the unsaturated polyester resin system. It is especially recommended for unsaturated polyester compounds that use aluminum hydroxide or calcium carbonate as fillers. It reduces the viscosity of unsaturated polyester compounds containing fillers. Therefore, it is possible to obtain higher filler filling volume. VOK is used ®- Disper W920 improves dispersion and shortens filler dispersion time, VOK ®- Disper W920 helps reduce settlement.
