Abstract:The overall market share of environmentally friendly water borne coatings is small compared to solvent borne alternatives. Today, they are used in a wide selection of market segments, such as wood and furniture, but also on non-wood substrates such as metals and plastics for industrial maintenance coatings, coatings for machines and equipment, and metal cans. Here, we present an additive technology based on ZnO nanoparticle dispersions that increases the chemical resistance of water borne coatings such as durability against solvents. ZnO is used in a nanoscaled form not only for optical reasons (to reduce haze in clear coatings) but also as it provides a very high surface area for this catalytic effect. We stress the importance of dispersion quality to produce a high-performance additive that is applicable in high-value coatings, such as high performance, high gloss, and transparent water borne coating formulations. Buhler has developed the chemomechanical process and uses this process to produce nanoscaled dispersions of inorganic oxides from agglomerated nano powders. Chemomechanical processing means chemical surface modification reaction under well-defined mechanical stress conditions. Oxylink™ is a chemo-mechanically synthesized additive that is highly efficient to improve the chemical resistance of water borne coatings.
