摘要:
Coating compositions, methods of applying the coating compositions, and articles incorporating the coating compositions are provided. The coating compositions are useful for coating a variety of substrates to improve the appearance and printability of the substrates. The coating compositions incorporate pigment system, a binder, and a thickener system. The thickener system incorporates a polyvinyl alcohol polymer and a boron containing compound such as boric acid. The coating compositions exhibit viscosity characteristics equal or superior to coating compositions incorporating conventional thickeners while providing cost advantages over conventional thickener systems.
摘要:
The invention relates to a method for producing a paper coating by adding a calcium-containing pigment into it. According to the invention, waterglass is added to the paper coating mixture, thus preventing solidification of the coating induced by calcium and keeping the viscosity of the mixture at a low level. Moreover, the invention relates to a relevant coating.
