Defoamer-for-Painting-Ink

Detailed Description

In the production and use of coatings and inks, the generation of foam is more common. This may be due to the mixing of resins, pigments, solvents, the presence of surfactants, and the mixing of air during construction. Bubbles can have a number of negative effects:

Affect the appearance quality: resulting in pinholes, fisheye and other defects on the coating surface, affecting the printing effect of the ink.

Reduce covering power and adhesion: foam will make the paint and ink cannot be evenly covered during construction, affecting its performance.

Increase the difficulty of construction: it may cause problems such as gun blockage and uneven rolling coating.

The role of Defoamer for coating inks is to eliminate these foams and ensure product quality and construction effect. It usually has the following characteristics:

Strong targeting: It can play a defoaming role for specific components in the coating and ink system.

Good compatibility: It has good compatibility with various resins, pigments and solvents, and does not affect the basic performance of coatings and inks.

Long-term performance: continuous inhibition of foam formation during storage and use.

For example, in the production of water-based coatings, due to the large surface tension of water, it is easy to produce foam, and the use of appropriate defoamer can obtain a smooth and flat coating.

In the ink printing process, the rapid elimination of foam can ensure the clarity of the print and color saturation.

In short, the defoamer for coating ink is of great significance for improving the quality of coating and ink and optimizing the construction process.
