BYK® -W 980

BYK®-W 980 by BYK is a wetting and dispersing additive to reduce viscosity and prevent fillers from settling. It contains 52% of renewable raw materials. It is used in ambient curing resin systems and polyester molding compounds. It improves the dispersion of all conventional fillers, such as calcium carbonate and aluminum hydroxide. It reduces the viscosity of the filled resin, allowing a higher filling level. In most cases, the settling of fillers during storage and processing is reduced. It is especially recommended for unsaturated polyester resins as well as acrylic, polyurethane and epoxy resins, and is highly effective in all areas of application. The recommended level is 0.5-1.5% based upon fillers. It lowers the viscosity, allows higher filling levels and improves glass fiber wetting. In pultrusion applications, the additive improves the wetting and dispersion of fillers, prevents the fillers from settling in the impregnation bath, and improves glass fiber wetting through lowered viscosity. It is particularly recommended for HMC polyester molding compounds, wet mat molding and pultrusion applications on the basis of UP/VE, epoxy and acrylic resins. The recommended level is 1-2% based upon fillers for HMC molding compounds & wet mat molding and 0.5-1.5% additive for pultrusion applications. It is listed in EINECS, TSCA, DSL, AICS, PICCS, IECSC, ENCS, NZIoC and ECSI. It is in line with Directive 2011/65/EU (EU RoHS 2), as amended by the Delegated Directive (EU) 2015/863 (EU RoHS 3), EU Directive 2002/96/EC (WEEE), EU Directive 94/62/EC (Packaging Waste) and CONEG Toxics in Packaging. It complies with REACH Regulation (EC) No 1907/2006. The shelf life of BYK®-W 980 is 42 months.
