Foam Control

SURFYNOL® 61 surfactant is a 100% active multifunctional surface active agent. Due to its volatile nature, SURFYNOL® 61 surfactant can evaporate from a system under use conditions and/or heating. Therefore, SURFYNOL® 61 surfactant is useful in applications where residual surface activity or contamination is undesirable, such as silicon wafer and glass cleaning. SURFYNOL® 61 surfactant can provide excellent wetting of polyethylene and polypropylene films. Upon evaporation, little to no surfactant remains to interfere with trapping or cause water sensitivity in printing inks. During the curing of silicones by the silane/alkene addition reaction, SURFYNOL® 61 surfactant can “block” platinum catalysts through complexation; this effect can be used to delay the curing reaction. However, the SURFYNOL® 61 surfactant typically flashes off upon heating to liberate the active catalyst and trigger the reaction.
