Matting Agent Silicon Dioxide For Industrial Paint

1. Silica coloring power: Coloring power (tinting strength) is the coloring ability of silica when white or colorful color paste and silica are mixed.

That is, the degree to which silica increases the light absorption effect of the mixed material system. This characteristic lies in the ratio of silica

to color and the characteristics of silica. When the ratio is constant, the coloring ability of a certain silica is its coloring strength, which is called

coloring power in the field of architectural coatings.When the silica particle size is small and the structure is low, the coloring power is high, but

when the particle size is less than 20nm, the coloring ability will no longer increase, or even decrease.

2. Silica gloss: When the silica particle size decreases or the structure increases, the absorption of residual oil by silica increases, which will increase

the viscosity of the paint. At the same silica concentration, the free paint (film chemical) on the coating surface decreases, so the gloss decreases.

When the surface oxygen functional groups or volatiles increase, the lubricity of silica in the binder increases, the viscosity decreases, the free paint

on the coating surface increases, and the gloss may increase.

Tips: 

* Before you use it, please test and make sure the dosage before using according different formulations and conditions.

* Recommended dosage is 3% -5%.
