Coating Additive | An additive that can effectively suppress foam generation

Defoamer is an additive that can reduce the surface tension of water, solution, suspension and other substances, prevent the formation of foam, or reduce or even eliminate the original foam . Its principle of action is to destabilize the bubble wall and rupture, thereby releasing the trapped gas.

The defoamer has the following characteristics:

1. Strong defoaming ability, less dosage;

2. Adding to the foaming system does not affect the basic properties of the system, that is, it does not react with the defoaming system;

3. Chemically stable, strong oxidation resistance;

4. The solubility in foaming solution is small.

Defoamers can be divided into organic silicon, polyether, polyether modified polysiloxane, etc. according to their chemical properties; Foaming type defoamer, defoaming type defoamer.

Defoamers are widely used in coatings, adhesives, detergents, cutting fluids, pesticides, pharmaceuticals and other industries.

BASF 2410

BASF 2410 is a representative of a new generation of defoamers, using the latest chemical structure of defoamers, different from traditional defoamers, this product also has Wetting effect.

Using this product can save 30%-50% of the dosage and reduce the cost of defoamer by at least 20%. In addition, the product is non-delamination, non-settling, and very fast foam breaking in acrylic and styrene-acrylic paints.
