SURFYNOL DF-37

A versatile, oil-based defoamer that is an effective foam-control agent in latex dipping processes as well as coating and ink formulations, among other industrial applications. Because of its wetting capabilities, the tendency for Surfynol DF-37 defoamer to cause fisheyes, craters, retraction and other surface defects is significantly reduced compared to most defoamers. This organic defoamer also provides inherent wetting properties. As a result, Surfynol DF-37 defoamer allows for dewebbing and consistent coverage of ceramic and synthetic forms used in latex dipping. Competitive dewebbing agents are usually water-based silicone emulsions, which can separate either upon standing or after freezing. This results in poor dewebbing performance and increases the potential for fisheyes and other defects, even after mixing. Surfynol DF-37 defoamer also promotes wetting of other lowenergy substrates like plastics and contaminated or improperly cleaned surfaces.
