BYK-LP W 25138

BYK-LP W 25138 is a wetting and dispersing additive that improves the wetting and dispersion of common fillers like calcium carbonate and aluminum trihydroxide in filled unsaturated polyester systems. BYK-LP W 25138 reduces viscosity enabling higher filler loading. It is not recommended for ambient curing systems as it may inhibit the curing process. BYK-LP W 25138 helps achieve uniform dispersion of fillers resulting in improved mechanical properties, reduced costs and enhanced sustainability in filled polymer formulations. The additive also prevents filler agglomeration and sedimentation during storage and transportation.
