HIGHLY BIODEGRADABLE LOW-FOAM WETTING AGENTS

摘要

The importance of additive technologies has increased as formulators convert to waterborne coatings because of the need to deal with problems not typically encountered in solventborne systems. Attention has recently turned to the environmental impact of additives such as wetting agents and defoamers. A class of highly biodegradable, low foam wetting agents has been developed to meet this demand. These materials provide excellent wetting under both equilibrium and dynamic conditions. The fundamental surfactant properties, environmental characteristics and relevant applications of these materials will be discussed.
