Surface-modified precipitated silicas
A surface-modified precipitated silica, useful as a matting agent, contains the silica having a polymer on a surface thereof. The surface-modified precipitated silica improves the transmission of a clear coating material, having a refractive index of n D 20=1.4492 and containing 5% by weight of said...
