METHOD OF IMPROVING STAIN RESISTANCE OF SURFACES

Method of increasing stain resistance of a surface of a porous layer formed by a binder and filler particles. In the surface, the filler particles are spaced apart and particles of precipitated calcium carbonate having a particle size in the range of 30 to 60 nm are incorporated into the layer in a...

Zusammenfassung:Method of increasing stain resistance of a surface of a porous layer formed by a binder and filler particles. In the surface, the filler particles are spaced apart and particles of precipitated calcium carbonate having a particle size in the range of 30 to 60 nm are incorporated into the layer in a sufficient amount to fill pores between the filler particles of the surface.
