This silica matting agent can be applied to various resin systems. It can not only improve the haze of leather coatings, but also preserve the original color of the leather. In focal systems, it delivers a beautiful white shade, good transparency after polishing and enhanced color brilliance. Additionally, it features good levelling properties and does not cause agglomeration or precipitation.
