Eastek™ 1200 Polymer Dispersion
Eastek™ 1200 is an aqueous dispersion of AQ™ 65S water-dispersible sulfopolyester resin. It is primarily used as a binder and film former in coatings, primers, printing inks, and overprint varnishes.
Eastman's Eastek™ 1200 is a 30% solids, water-based dispersion of Eastman's AQ™ 65S, a film-forming, water-dispersible sulfopolyester resin with a glass transition temperature of 65°C. Eastek™ 1200's sulfopolyester particles are stabilized as an aqueous dispersion without surfactants, amines, or cosolvents. It is typically used as a film former and binding resin compatible with various substrates. The small sulfopolyester particle size of Eastek™ 1200 allows for rapid drying and the formation of clear thermoplastic films with a high level of gloss. Films formed with Eastek™ 1200 have a low coefficient of friction and are alcohol resistant, nontacky, and nonblocking. This makes them useful in heat seal coatings for packaging applications. Films of Eastek™ 1200 can be made on packaging films and foils and wound to then be heat sealed to other materials at a later time.
Coatings and inks formulated with the Eastek™ 1200 sulfopolyester dispersion have decreased drying times, excellent gloss, good alcohol resistance, and a low coefficient of friction. The reduced drying time provided by Eastek™ 1200 allows for improved efficiency and faster run speeds during printing and coating operations.
Eastek™ 1200 also is a useful primer for wood coatings, where the sulfopolyester polymers penetrate well into porous surfaces. Since the sulfopolyester dispersion is also free from amines, which cause wood to yellow, Eastek™ 1200 primers preserve the natural color of wood.
