SILFOAM^® SE 40

SILFOAM^® SE 40 is usually admixed with the formulations or liquors to be defoamed before the process begins, and extra may be added as necessary during the course of the process. To improve the accuracy of metering, SILFOAM^® SE 40 can be prediluted with cold water in a ratio of 1:5 to 1:10. Preliminary tests should be carried out to ensure that SILFOAM^® SE 40 is suitable for the application and to determine the amount required.

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.
