D1486 LOW GLOSS RADIATION CURABLE COATING FOR CONCREATE FLOORS

摘要

Radiation-curable coating compositions for a surface such as a concrete floor, which include at least one multi-functional monomer or oligomer, at least one photoinitiator, at least one glossy band matting agent, and at least one matte band matting agent are described and claimed. These low gloss coating compositions allow for application of the coating composition over an area larger than a UV radiation source, while minimizing the formation of gloss bands or gloss lines that exhibit a different level of gloss in the areas where light leakage from a side light shielding of the UV radiation source results in a very weak radiation intensity, as compared to the areas subjected to high radiation intensity. These low gloss coating compositions are optionally clear topcoat compositions. In addition, a method for coating a surface with a radiation-curable coating composition that results in a cured surface with minimal differences in gloss exhibited following curing by a UV radiation source, and a surface coated with the radiation curable coating compositions of the instant claimed invention are described and claimed.
