High Delustering Efficiency Silica Matting Agent For Water Based Paint
Introduction
Silica matting agent by using the silica-gel process products can be obtained which have a harder morphology, it can produce standard silica and after treated products. After treatment means that the silica surface can be partially modified with organic (waxes) or inorganic materials. And shows a very high matting efficiency, especially in water-based systems.
Characteristics
High transparency:Strictly control particle size distribution of product, and give better transparency for leather coating.
Excellent dispersibility Easy to add:The delustrant can easily disperse in both polar solvent and aqueous solution. A delustering effect may reached by just using normal dispersion machine to disperse in high speed for 15-30 minutes.
