Filler Wetting and Dispersing Additive for Unsaturated Polyester Systems

Applications: 
　　JS-V966 is particularly suitable for unsaturated polyester resin systems filled with fillers such as aluminum hydroxide, titanium dioxide, calcium carbonate, or barium sulfate (used individually or in combination), as well as natural stone powder. In filled lamination systems such as PVC profiles, pipes, sanitary ware, or cultured marble, JS-V966 enhances the coupling performance between resin and fillers, reduces viscosity, increases filler loading, improves strength, water resistance, and stain resistance, and provides exceptional wetting and dispersion effects for pigments and fillers.
　　JS-V966 is used in body filler production to facilitate filler dispersion, increase filler loading, improve sanding performance, and enhance product quality.

Features and Benefits: 
　　JS-V966 reduces the viscosity of highly filled unsaturated polyester systems, thereby maximizing filler loading. It offers outstanding coupling performance with low dosage requirements. Additionally, it enhances the dispersion of fillers and pigments within the resin system, significantly reducing and eliminating settling. It provides exceptional low-foam wetting action for filled slurries.

Recommended Dosage: 0.5% – 1.5% based on filler weight 
Usage Instructions: JS-V966 should be uniformly mixed with the resin prior to adding fillers. 
Packaging: Available in 50 kg plastic-coated drums and 200 kg drums with plastic liners. 
Storage and Transportation: Re-seal the container tightly after opening to prevent contamination by dust or moisture.
