New waterborne catalyst for two-component waterborne polyurethane coatings Two-component waterborne polyurethane (2K WB PU) coating technology has been commercialized since 1990, when such products were developed primarily to reduce the problem of VOC content, which was not feasible to solve using solvent-based technology.1 Since the introduction of two-component waterborne polyurethane (2K WB PU) coating technology,...
Recently, chemists from Konstanz developed a new catalyst for the direct manufacture of polyethylene dispersions in water. This opens up the prospect of environmentally friendly, solvent-free coating production. Polyethylene (PE) is one of the most important types of plastics today. It is used in a variety of everyday products, from plastic bottles, pipes and skiing...
The application of catalysts in coating auxiliaries Coating auxiliaries, also known as paint auxiliaries, are auxiliary materials for the preparation of coatings, which can improve the performance of coatings and promote the formation of coating films. There are many types, including catalysts, toughening agents, emulsifiers, thickeners, pigment dispersants, defoamers, leveling agents, anti-crusting agents, matting agents,...
