2,4,7,9-tetramethyl-5-decyne-4,7-diol >98.0%

Description :

As a typical Gemini surfactant, Surfadol 541 provides multifunctional properties such as dynamic surface tension reduction, foam control, water sensitivity reduction, and viscosity stabilization. Available in solid, liquid or powder form, Surfadol 541 is widely used as wetting agent or anti-foaming agent in waterborne coatings such as electro-deposit coatings, industrial coatings, etc., as well as water-based inks such as gravure inks, flexo inks and inkjet inks. The unique product can prevent surface defect problems such as fisheyes, crawling, and cratering on low-energy substrates, compared to fluorosurfactant or silicone surfactants.
