SMA® multifunctional resins are a family of low molecular weight resins which include styrene/maleic anhydride, amic acids, imides, copolymer base resins, partial esters of the base resins and aqueous ammonia salt solutions of the base resins and ester resins. SMA® resins are used in diverse applications such as paper sizing, powder coating, pigment dispersions, inks, over print varnishes, leather retanning, microelectronics fabrication and processing, carpet/textile cleaners and floor care products. SMA® resins can function as polymeric surfactants in dispersing and emulsifying applications, as high functionality cross-linking agents or as chemical intermediates in the production of specialty polymers.
