Grinding colorants are viscous mixtures used to make inks, pigments, and coatings. It usually consists of pigments, solvents, and additives. Colorants play an important role in industrial production and the arts, but the resulting foam problem often plagues the production process. EFKA-2570 defoamerAs an important tool to solve the problem of foam.
OneRaw materials
The main raw materials of EFKA-2570 defoamer include silicones, surfactants and solvents. Silicone-based defoamers provide excellent defoaming and stability, surfactants help reduce surface tension and improve dispersion, and solvents are used to adjust the flow and concentration of defoamers.
IIMechanism of action
Silicone defoamers can form a thin film on the surface of the liquid, preventing air from entering the liquid and reducing the surface tension of the liquid, while the surfactant can be adsorbed on the surface of the foam film, destroying the surface tension of the foam and causing the foam to dissipate rapidly. The role of solvents is to adjust the properties of the defoamer to suit the properties of different pigments and solvents.
IIIScope of application
EFKA-2570 defoamerIt is widely used in industries such as inks, pigments and coatings. It can be used for aqueous, oily or solvent-based abrasive colorants, which can effectively reduce foam generation and improve the stability and flow of colorants
1.Ink production: Defoamers can reduce foam problems in the ink production process and improve the quality and performance of inks.
2.Art: In the process of making and blending pigments, defoamers ensure smooth mixing and homogeneous dispersion of pigments.
3.Coating industry: Grinding colorant defoamer is widely used in the coating production process, which can reduce the foam generated during the coating application process and improve the flatness and appearance quality of the coating.
4.Electronic materials: In the preparation process of electronic materials, defoamers can reduce the adverse effects of foam on product performance and improve product quality.
