99% Content Nano Silica Powder For Coil Coating

SN-930 Silicon Dioxide

In daily life, when we use paint, we often find that the paint has dripping and even wrinkling. Then we can add an appropriate

amount of silica to the paint. Silica can help us solve these problems.

Adding silica to the pigment can not only prevent the precipitation of the pigment, but also improve the adsorption of pigments

and dyes and improve the dispersibility. When used as a filler for emulsified paint, it can improve thermal stability.

Silicon dioxide has thixotropic properties. Adding a small amount of silica to the paint can eliminate the droplet sedimentation

phenomenon of the coating. In unsaturated polyester paint, as long as 0.5-2% of silica is added, this paint can be applied on a

vertical surface at a time. 500g/m2 will not cause droplets and wrinkles.

In order to meet the requirements of paint and ink matting agents for silica, foreign countries have developed and produced special

matting agents. When nitro varnish and similar coatings contain precipitated Silica Matting Agent, it can improve the non-precipitation

performance of the paint and make the coating easy to disperse, with only a small amount of thickening effect, good suspension,

good matting properties, high transparency and good wear resistance.

Adding 0.5% of silica to printing ink has good printing effect, can eliminate the influence of undispersed ink penetration, improve the

washability of printed materials, and increase the gloss of color.

In addition, silica is also used in pesticides, medicines, adhesives, toothpaste and daily cosmetics to varying degrees and plays

various beneficial functions.
