3.5.4Surfactant content of the formulation

Оглавление

High surfactant content, required for example to wet critical substrates, often reduces the efficiency of a defoamer. In such formulations the use of stronger, more hydrophobic defoamers is recommended. In formulations which are sensitive to strong defoamers, greater amounts of a milder defoamer are often the only solution.
