GREESOL™ A04E series surfactants are the kinds of gemini non-ionic surfactant that the main component is the symmetric compound of alkyne diol. As the multifunctional additives containing wetting, defoaming, dispersing properties these surfactants with the excellent surface activity such as the decreasing surface tension, controlling foam and reducing water sensitivity because of the unique chemical structure can be used in waterborne industrial coatings, waterborne wood coatings, plastic waterborne paint, waterborne ink, waterborne varnish, pressure-sensitive adhesive, paint and dye manufacturing, metalworking fluids, fluxes, pesticides etc.
