After the construction of the paint, some people will find some places that will foam because of the direct heat and the surface. The localized part of the paint film loses adhesion, and the phenomenon of separation from the surface of the substrate and bubbling affects the appearance and is easy to fall off. Therefore, we need some additives to eliminate the coating defoaming agent, then the coating defoaming agent is what? What are the effects of defoamer for paint?
What is the paint defoamer?
The coating antifoam is a silicone-free composite antifoaming agent. It is suitable for eliminating foams of styrene-acrylic latex, ethylene-propylene latex, pure acrylic latex, vinyl acetate latex, etc. due to its high quality defoaming ingredients.
The role of defoamer for paint:
1. The addition of the antifoaming agent may be carried out after the foam is not formed or formed. After the defoaming agent is added, the uniformly dispersed defoaming agent will penetrate into the foam elastic film and be distributed in the bubble film, and the surface tension is lowered to cause the foam to rupture.
2. The uniformly dispersed defoaming agent penetrates into the thin layer of foam and forms a monomolecular film, which reduces the adhesion and facilitates the breakage of the thin layer.
3. The anti-foaming agent contains hydrophobic particles that reach the surface of the thin layer and begin to adsorb the surfactant at the top of the thin layer. The foam ruptures due to the gradual disappearance of the surfactant.
Zilibon is a manufacturer with 16 years of application experience. It has far more defoaming technology than other antifoaming agents in the market. From the above cases, we prove the strength of our Zilibon defoamer. We have a group of excellent defoaming engineers, and An independent laboratory that facilitates defoaming experiments with foams that are difficult for customers to solve.
