1. Foaming agent

In the process of industrial production plays a temporary role in bubble control, in the future may have a certain amount of bubble control ability, may also be poor. The defoaming agent penetrates the bubble film through the surface tension, diffuses and replaces the bubble film layer, and the film layer becomes thinner, so that the generated foam bursts.

2. Foam suppressor

The additives contained in the final product. After the production of paint, after storage, there is still a satisfactory foam control ability in coating, so, to have a good defoaming ability persistence, generally use this kind of defoaming agent in paint. The foam suppressor and the bubbling substance in the liquid are absorbed on the bubble membrane wall at the same time. The low surface tension of the bubble film adsorbed with bubble suppressor makes the bubble film thinner, and the surface energy of the foam is unbalanced, so the bubble film becomes unstable and will break in the process of floating on the page.

3, defoaming agent

Also known as air releasers. Mainly for the high viscosity solvent-based paint in the single bubble, they are difficult to rise to the liquid level and eliminate. Defoaming agent can improve the flow in the air, so that the adjacent foam aggregate and merge with each other, the volume becomes larger, the speed of movement to the surface is accelerated, so that it is easy to break.
