Coating additives | An additive that can effectively inhibit foam generation

Defoaming agent is an additive that can reduce the surface tension of water, solutions, suspensions and other substances, prevent the formation of foam, or reduce or even eliminate the original foam. . Its working principle is to destabilize the bubble wall and burst it, thereby releasing the trapped gas.

Defoamer has the following characteristics:

1. Strong defoaming ability and low dosage;

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

3. Chemically stable, strong oxidation resistance;

4. Low solubility in foaming solutions.

Defoaming agents can be divided into silicones, polyethers, polyether modified polysiloxanes, etc. according to their chemical properties; they can be divided into antifoaming agents according to their characteristics. Foaming defoaming agent, defoaming defoaming agent.

Defoaming agents are widely used in coatings, adhesives, detergents, cutting fluids, pesticides, medicine and other industries.

BASF 2410

BASF 2410

BASF 2410 is a representative of the new generation of defoamer. It adopts the latest chemical structure of defoamer. Unlike traditional defoamer, this product also has Moisturizing effect.

Using this product can save 30%-50% of the dosage and reduce the cost of defoaming agent by at least 20%. In addition, this product also has the characteristics of non-stratification and non-settlement, and has very fast foam breaking ability in acrylic paints and styrene-acrylic paints.
