| SILFOAM® SE 40 is a relatively heat-resistant, viscous, non-ionic antifoam emulsion. Conventional defoaming emulsions often form slightly oily deposits under the effect of heat during use. SILFOAM® SE 40, on the other hand, is extremely stable, even at temperatures around boiling point. Application: SILFOAM® SE 40 can be used in closed systems at a pH of between 3 an 11, and from ambient temperature up to 130 °C. SILFOAM® SE 40 is therefore generally recommended for critical systems, especially high temperature and jet dyeing systems, in which it acts as a foam suppressant and deaeration agent. Apart from textile applications, it can also be used in processes that would be contaminated by the oily deposits formed when conventional antifoam agents are subject to effects such as heat, shearing or general compatibility problems.
