UV-Curable Fluorocarbon Polyurethane Coatings for Marble Kitchen Countertops

Marble kitchen countertops and other natural stone surfaces are often stained by various food ingredients contaminants during daily use require frequent cleaning, which is time-consuming leads to the wasting of water. If surface coated with a hydrophobic oleophobic coating, ingredient contamination becomes easier wipe clean. Therefore, UV-curable monomer fluorocarbon branched chains was synthesized added coatings in different ratios. The preferred formulation that meets basic performance requirements coatings, has best properties, designed selected. upgraded adding hydrofluoric ether (HFE) solvent. These formulations were tested for hydrophobicity oleophobicity under conditions. addition an HFE solvent improves initial water cetane contact angles paint film, as well Moreover, have better stain resistance. degree improvement positively correlated polyurethane coating good adhesion on marble been polished primed. Due presence TEOH-6 instead PFOA, low content functional groups effectively located film makes quite stable safe.
