Self-Crosslinking Water Base Latex with Low VOC Emission

Abstract

ABSTRACTHere we report the preparation of functionalized latexes with isocyanate groups through an emulsion terpolymerization of BA/St/TMI. The emulsions were stabilized with two surfactants, EF-800 or MA-80; the TMI acted as a self crosslinked promoter during the film formation. We found a strong dependence of surfactant type in particle size and particle number. Moreover colloidal stability of latexes by a period of time was different, and the best colloidal stability was obtained with EF-800 surfactant. Swell index and mechanical properties of latex films were studied.
