COMPOSITION FOR FORMING A COATING AND COATING APPLIED WITH THE COMPOSITION

摘要

The present invention relates to a composition for forming a coating and to a coating applied with the composition, and more particularly, to a composition for forming a coating and to a coating applied with the composition, which significantly increase in coating hardness to ultimately enhance the durability of materials such as substrates on which the coating is applied, wherein the composition consists of: an oligomer obtained by simultaneously or sequentially polymerizing a 3-functional silane represented by the general formula R1SiX3, a 3-functional silane represented by the general formula R2SiX'3, and a 4-functional silane represented by the general formula SiX"4 (where R1 is either an alkyl group or a phenyl group, R2 is a hydrocarbon group which includes one or more unsaturated bonds, and X, X', and X" are mutually identical or different hydrolyzable groups); a radical initiator; and a solvent which dissolves the oligomer and the radical initiator, to significantly improve the hardness of the coating by means of a Si-(C-)nSi structure (where n is a natural number from 2 to 4), particularly by enabling heating during the polymerization of a siloxane oligomer as a starting material to produce up to 4 C bonds in an Si-C-Si bond.
