Читать книгу Additives for Water-borne Coatings - Wernfried Heilen - Страница 72

The numerous ways of varying synthetic polymers provide the ideal opportunity to tailor-active ingredients for specific coating systems. Commonly used active ingredients are fatty acids, alcohols based on fatty acids, polyethers, alkyl amines, alkyl amides, tributyl phosphate or thio ethers. The compatibility of oils in application systems can be easily controlled by varying their polarity. Polar oils are often used in combination with other defoamer active ingredients to control the compatibility of the formulation.
