BYK-W 969

BYK W 969 is a monofunctional, deflocculating wetting and dispersing additive for mineral-filled, amine- preaccelerated polyester putty compounds as well as epoxy, acrylic, and polyurethane resins used in industrial applications. BYK W 969 improves the wetting and dispersing speed of fillers during dispersion and reduces viscosity to enable an increased filler content to be achieved. The higher filler content improves sandability and durability of applied coatings. BYK W 969 leads to a considerably increase in gelling time and is suitable for all filled polyurethane systems used in industrial equipment and machinery. Due to its OH functionality, BYK W 969 is incorporated in the polymer matrix and is therefore suitable for polyurethane systems in which fogging and emissions are critical.
