Unexpected failures may appear after paint application, drying and aging. Surfactant leaching is one such failure, and is discussed in detail in this article.
Due to their tailored system compatibility, the new sili¬cone surfactants are suitable for use in both aqueous one-component systems as well as in aqueous two-com¬ponent polyurethane and radiation-curable systems.
Calfax DB-45 is the go-to surfactant in emulsion polymerization for plastic modification and other applications at elevated temperatures, due to excellent thermal stability.
H.B. Fuller Co. has signed an agreement to sell its surfactants, thickeners and dispersants business to Tiarco LLC, a wholly owned subsidiary of Textile Rubber and Chemical Co. Inc.
Safety and performance take center stage in Carpenter Co.'s line of nonionic surfactants, which provide a range of EO/PO block copolymers that serve a wide variety of markets where defoaming, wetting and emulsifying are critical.
Lindsay Doyle's lube emulsion and her customer's acrylic dispersion both crashed and separated like curdled milk. What had caused both systems to crash, and how were the causes related?
Maxemul reactive surfactants act as efficient emulsifiers providing colloidal stability and are chemically bonded to the polymer particles during free radical polymerization. The enhanced stability and mitigation of surfactant leaching during and after film forming significantly improve water resistance and barrier properties of the latex binder as a replacement of conventional surfactants.
