Abstract
The present invention relates to a resin composition for coating, and a coating film comprising a cured product thereof as a coating layer. Particularly, the present invention relates to a resin composition for coating, and a coating film comprising a cured product thereof as a coating layer, wherein the resin composition for coating comprises a siloxane resin that is chemically bonded by compounds comprising alkoxysilane and diol, which comprise epoxy or acryl within the chemical structures thereof.
Claims3
