Product Usage
Usage: When used in silicone rubber, it can improve the strength and product quality of the rubber. When used in coatings, it features ultra-fine particle size, low sedimentation tendency, and good dispersibility, which can reduce the amount of dispersing agents required in paints and coatings. It is also widely used in the glass industry, artificial quartz stone slab manufacturing, and other industries.
Packaging: 25 kg/bag, in paper-plastic composite bags. Alternative packaging options are also available upon customer request.
