BYK W 908 is a wetting and dispersing additive that greatly reduces viscosity. It improves flow behavior and leveling without impacting cure or color. BYK W 908 is particularly suitable for highly filled systems due to its ability to lower viscosity. As a result, it enhances application properties and improves substrate wetting. BYK W 908 allows formulators to increase solid loading for higher performance without compromising on other properties. The product is REACH compliant and suitable for applications requiring strict regulatory approval.
