In general, the larger the average particle size of the matting powder, the higher the matting efficiency.
If there are a large number of "coarse" and "fine" particles, the distribution is uneven, causing thickening and excessive roughness
The higher the porosity of the matting powder, the higher the powder content per unit weight.
The reduction in gloss is the effect of particle size
The same particle size, the better the effect of high porosity
Bulk density is not directly related to matting performance
Small particles, small bulk density, large porosity, larger surface area, and correspondingly higher oil absorption
Large oil absorption, generally better matting performance
Better surface treatment matting performance
