The role of decentrals in coatings

Differentians plays a very important role in coatings, mainly in the following aspects:
Diversified pigments: The paint in the coatings is often solid granular. If it is not decentralized, the pigment will gather in the coating to form a cluster or precipitation, resulting in uneven distribution of the pigment. The dispersant can disperse the pigment into the liquid medium by reducing the attractiveness and surface tension between the pigment particles, so that it is evenly distributed in the entire coating, and the color uniformity and luster of the coating are increased.
Improve the stability of coatings: Differentians can prevent the aggregation and precipitation between pigment particles, thereby improving the stability of the coating. Stable coatings are not prone to problems such as separation, precipitation or block, and extend the service life of the paint.
Reduce viscosity: The viscosity of the coatings increases the viscosity of the paint, which affects the construction performance and coating quality of the coating. The dispersant can form a slightly thin dispersant wrap layer on the surface of the pigment, reducing the friction and interactive force between the particles, thereby reducing the viscosity of the coating and improving its liquidity and coating performance.
Enhanced anti -hug adhesion capabilities: The coating is prone to adhesion during storage, transportation, and construction, that is, the skin or adhesion occurs on the surface of the coating. Differentians can form a protective film on the surface of the coating, reducing the contact between coatings and the external environment, and reducing the occurrence of sticking.
In short, decentrals play an important role in scattered pigments, improve stability, reduce viscosity, and enhance anti -holding ability to ensure that the coating has good coating performance and coating quality.
