BYK W 996 is a universal and cost-effective wetting and dispersing additive for virtually all closed mold applications. BYK W 996 is very effective in highly filled systems. It improves the wetting and dispersion of mineral fillers. This achieves a lower viscosity and enables higher filler loading. BYK W 996 can be combined with BYK-W 9010 if high additive quantities are required. BYK W 996 is particularly suitable for applications based on epoxy resins and unsaturated polyester systems where it stabilizes viscosity. As a dispersing agent, BYK W 996 helps incorporate fillers evenly into formulations. This results in improved mechanical properties, higher loadings and a better surface finish of final products.
