"Cleaning agent to clean the superfu00eccie of a substrate, the composition of the sub coating to form a sub coating on the superfu00eccie of a substrate.Process for forming a coating fotocataliticamente hidrofilificu00e1vel on superfu00eccie of a substrate together, and state ".There are described a process to form a coating fotocataliticamente hidrofilificu00e1vel,Involving a process for treating the surface of a substrate prior to the formation of a coating fotocataliticamente hidrofilificu00e1vel,You can form a good coating fotocataliticamente hidrofilificu00e1vel, and a cleaning agent and a composition of sub - coating process.The process to form a coating fotocataliticamente hidrofilificu00e1vel comprises steps: cleaning the surface of a substrate with a predetermined cleaning agent; coating a liquid.The coating on the substrate fotocataliticamente hidrofilificu00e1vel treaty; and curing the coating or, alternatively,Comprises the steps of: cleaning the surface of a substrate with a predetermined cleaning agent; applying a predetermined composition of sub - Coating on the surface of the substrate to F.Information sub - coating; coating a coating liquid fotocataliticamente hidrofilificu00e1vel on the sub coating; and curing the coating to form a coating fotocataliticamente hidRofilificu00e1vel. The cleaning agent comprises at least one member selected from the group consisting of a surfactant, an abrasive, an acid and a base.The composition of the sub coating for the sub coating comprises at least one particle of inorganic oxide or a silicon or a silicon precursor, and a solvent.
