UV Curable Coatings and Paints Containing Fluorin for Exterior Applications

摘要

A kind of UV curable fluorine-containing acrylate oligomer (FCA) was synthesized based on fluorinated alkyl hydrocarbon modification. The formulations of varnish and pigmented paints were developed using FCA as a main component by selecting different reactive diluents, photointiator, pigments and additives. The developed resins were demonstrated to have strong capabilities of weathering resistance, light resistance, chemical resistance and dirt resistance. They have been successfully applied in the areas of interior and exterior architectural coatings on different substrates, such as aluminum-plastic composite panel, plastics and aluminum alloys. Moreover, they are suitable to be applied in the special conditions with high humidity and temperature such as kitchen, bathroom, laboratory, etc.
