Different Treatment Methods Matting Manifested Different Effects
- Jul 19, 2016 -

For conventional matting, we all know that the larger the average particle size of a matting agent, matting efficiency is higher. However, if the particles are too large, and will lead to the film surface is too rough, affect the feel and appearance.

Select the porosity (pore volume) higher product. The larger the porosity, the unit weight of powder content will be higher, the better the performance of extinction.

The average particle diameter of the matting agent is smaller, the better the transparency of the film, but the corresponding extinction efficiency will be reduced, be noted that the fines content is too high, it will have a negative impact on transparency.

In fact, the surface treatment can also affect other effects matting.

Organic matting treatment: anti-settling performance will be better. Matting agent with the extension of storage time of the coating, there will be layered with precipitation but this is only a short time to a certain extent, the time is too long, then it will precipitate

Matting wax treatment: general use in the varnish which, as the varnish is not convenient to add silica, so add the varnish wax treatment matting, anti-settling, knot lumps, and good compatibility with the solvent-borne coating systems , no heavy float adhesion problems, but rather increase film scratch resistance, enhancing the film smoothness, the downside is that by silica matting agent, matting wax process somewhat less, the film transmittance slightly difference.
