BYK® -W 969

Technical Datasheet | Supplied by BYK
BYK® -W 969 by BYK is a solution of a hydroxy-functional alkylammonium salt of an acidic copolymer. Acts as monofunctional, deflocculating wetting and dispersing agents. It wets the filler particles and lead to a moderate interaction of the particles. This additive can be crosslinked into the polymer matrix because of its OH functionality. It improves the wetting and dispersing rate of fillers during dispersion and dramatically reduces viscosity, so that higher filler loading is possible. BYK® -W 969 is recommended for PUR adhesives and suitable for acrylic, epoxy adhesives. Used for systems where fogging and emissions are critical issues (e. g. automotive applications). Its recommended level is 0.5 - 1% based upon filler.
