PVP，used in coating as a leveling agents

기재 안료의 함량이 높으면 요변성이 뚜렷하고 유동성이 좋지 않으며 필름이 튀어나오기 쉽습니다. 그러나 스티렌 아크릴 에멀젼에 PVP 및 기타 레벨링제를 첨가하면 안료 함량이 높고(불휘발분 함량 70% 이상) 점도가 높으며 레벨링이 양호하고 매끄러운 도막을 얻을 수 있으며, 매끄러운 도막을 얻을 수 있습니다. 압착하여 얻을 수 있으며, 도료량이 적고, 광택이 좋고, 내오염성이 우수합니다.

In recent years, the use of microencapsulation technology can further improve the dispersion stability of pigments, improve the covering ability and anti-fouling properties of coatings. In this paper, vinylpyrrolidone was polymerized in a suspension system composed of pigment and water, the solid particles were dispersed at the same time, and then vinyl acetate monomer and butyl acrylate were introduced to polymerize on the surface of solid particles to form a film, and finally a stable coating dispersion was obtained. The coating obtained by this coating can prevent food contamination.
