We produce various ranges of defoamers mainly for solvent-based coatings. Chemically, they are based on Modified Dimethyl Polysiloxanes and Silicone Free Polymers.
Foam can be generated in the production during grinding and stirring, as well as during application, for example, brushing, rolling and low pressure spraying. It also generated through application of a coating on porous substrates. Wood is the most common example for porous substrates.
However, foam is an unwanted physical state, that all paint formulators want to eliminate. It results in uneven finishing and in worse case: it will reduce the protective property of the coating to the substrate.
AFCONA additives defoamers added to eliminate foams and Its unwanted site effects at production and application stage.
