Toynol® FS-204H Acetylenic Diol Glycol Solution
Toynol® FS-204H Acetylenic Diol Glycol Solution
Abstract
Toynol® FS-204H is a nonionic surfactant based on a mixed system of 2,4,7,9-tetramethyl-5-decyne-4,7-diol (acetylenic diol) and ethylene glycol, with an active matter content of about 75%. It combines efficient surface tension reduction with defoaming, serving as both a wetting agent and a defoamer, and provides long-lasting antifoaming. It is suitable for waterborne coatings, waterborne adhesives, waterborne colorants, semiconductor processing materials, printing chemicals and powder commercialization modification, among many other waterborne systems.
