Utilizing novel chemistry and biobased materials, EcOSYNTHETIX has created a number of new waterborne biobased polymer technologies. One of the technology platforms involves sugar-acrylic copolymers, a patented technology enabling the synthesis of sugar based building blocks, referred to as "sugar macromer". Sugar-based copolymers are being developed for applications including adhesives, inks, and toners, among others. The PSA performance of the first generation sugar-acrylics will be reviewed. Advantages include a broad spectrum of performance, true repulpability for paper recycling, low VOC's, and biobased content. A second technology platform involves starch nanospheres that are being developed for packaging adhesives and value added corrugating adhesives. These technologies open up the development of new adhesive products for many applications, ranging from biodegradable school glues as biobased alternatives to waterborne polyvinyl acetates, to truly repulpable PSAs for industrial coating applications.
