As one of the world’s leading producers of binders and polymer additives for coatings, construction chemicals and adhesives, the Munich-based Wacker Group launched a new cutting-edge product at CHINACOAT 2009. The water-based dispersion called Vinnapas EF718 enables the formulation of ultra low VOC and low odor interior paints. The product represents a new advancement in VAE polymer technology and was developed for the China market based on a conjoint analysis with Chinese customers targeting the mid-end odorless interior paint market, according to the company. The emulsion is an aqueous dispersion of a vinyl acetate-ethylene (VAE) copolymer. It was developed as a low VOC, APEO-free binder for environmentally friendly and low odor paints. It offers scrub resistance, early water resistance and low odor and can be used as a cost competitive replacement for a variety of technologies including vinyl acrylics and styrene acrylics. As an application binder for architectural coatings, Vinnapas EF718 offers a balance of performance with the ability to formulate low odor paints at ultra low VOC levels (<10 g/l). It can also be formulated over a broad range of PVCs successfully replacing other technologies. Vinnapas EF718 requires no coalescent to form a film because of the “self-coalescence” of VAE copolymers. This provides a polymer that requires no cosolvent to form a film and therefore can be formulated into low odor low VOC paints.
