Matting Agent For Economic Coatings

Description



1, Silicon Matting Agent is a syntetic, micronized amorphous silica gel having porosity and high purity. The chemical structure of this product is based on Silicon Dioxide (SiO2). Matting agents are used to reduce the gloss in a variety of coatings applications. The application segments for silica gel matting agents include wood furniture coating, industrial coating, coil coatings, automotive coatings and decorative coatings as well as printing inks, leather coatings and textile coatings


2, Silicon Matting Agent usually used for general wood coatings, industrial coatings,plastic coatings. The general process is to attain silicate liquid by the acid neutralization reaction of sodium silicate solution, then processing it with filtering, washing, drying, finally let is go through our advanced crushing equipment for ultrafine grinding. It is a kind of virulent insipidity, nonflammable fluffy white powder, which is soluble in caustic soda and hydrofluoric acid only. Other characteristics are no decomposition, discoloration under high temperature, but with certain water imbibitions.


Feature


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, Excellent Transparency: Products high purity lead the refractive index inosculate with resin index.

3, Highest matting efficiency: High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.


Application Area


1, General Industrial Paints, General Metal baking Paints, General Decorative Paints.

2, General NC wood Paints, PU wood Paints, furniture wood Paints, wood decorative Paints.

3, General Printing Inks, Gravure Printing Ink, Offset Printing Ink, Screen Printing Ink, Printing Packing Material.


Superiority


1, We are the realizable supplier for some international company and export to many countries. Such as AkzoNobel, Valspar, Nippon Paints, Dgl Camel, Taiho Paints and PPG.

2, We set up a research and development center to study new silica products to use special application.

3, We are the largest production of silica gel in China, and focus on Paint/Coating Market about 25 Years, with advanced technology and good experience to develop paint silica matting agent products.
