Matte Film Paint Additive Silicon Dioxide Powder

Why people use silica Matting Agent?

Silicon dioxide has excellent dielectric properties, low thermal expansion coefficient and other comprehensive properties.The 

high filling of silica can reduce the cost, improve the thermal conductivity, reduce the coefficient of thermal expansion, and 

increase the strength. However, with the increase of the filling amount, the viscosity of the system will increase sharply, the 

fluidity and permeability of the material will become worse, and the dispersion of silica in the resin is difficult, and the agglomeration

problem is easy to occur.The silica matting agent's main material is silicon dioxide, the properties that silicon dioxide has, the 

same silica matting agent has. People often use silica matting agent in coating for create matte effect.

How does silica matting agent works in advertising film coating?

Combinating with glossy production of coating's surface and factors that are effecting the glossy. People consider that create 

matte effect is to use different ways to destroy the coating's smoothness and increase the coating surface micro roughness. 

To decrease the light reflection value of coating can be classified into physical site and chemical site.

Physical site: adding silica matting agent into the production of coating filming can form a rough surface to increase the scattering 

of light and reducing the situations of light reflection.

Chemical site: adding silica matting agent into the coating can help to adsorb the light structure or light's gene to get low glossy.

People need different glossy value's coating with the higher living level. Top grade matte coating is attractive due to its natural, 

elegant. On other side, matte coating can cover the tiny coating flaws to make the coating' s appearance being totally the same. 

So how to choose the suitable coating to arrive the expected result depends on the produced coating's properties.
