Better Water Resistance SIlica Matting Agent Used For Water-Based Coatings
Description
Silica Matting Agent specialized used for Matte/Semi-gloss waterbased Coatings. It provided high matting efficiency, excellent coating appearance and high transparency. As well as low oil absorption, easy dispersion and smoothly touch with minimal impact of viscosity. Generally, the untreated products provide highly effective matting at minimal addition levels, thus enabling the formulation of clear, low-gloss finishes with high transparency and chemical resistance properties.
Characters
1, Easy to Disperse: Advanced rubbing technology makes narrower distribution of diameter of granules, so that matting agent can be easily added in any production procedure and can be easily dispersed, which saves the processing time.
2, Strong Water Resistance.
Application
1, Water-based wood coatings, water-based industrial coatings, water-based inks, water-based plastic coatings, water-based metal substrates.
2, Clear and pigmented woodcare applications, such as NC wood coatings, PU wood coatings, unsaturated polyester wood coatings.
Advantage
We located in a modern city, as a research, development and production for chemical raw materials, as well as one of the largest production bases of silica in China. We will continue to invest in research and development, application technology and production capacities in emerging markets. We had set up a research and development center to study new silica products to use special application
