COATING MATERIAL FOR FORMING VITREOUS COATING FILM, METHOD OF COATING WITH THE SAME, AND COATER

摘要

The invention relates to a coating material for forming a vitreous coating film, characterized by comprising compounds represented by the following general formule (1) to (3): R<1>pSi(OR<2>)4-p (1), R<2>(OSi(OR<2>)2)qOR<2> (2), M(OR<3>)r (3) wherein R<1> is a polymerizable organic group; R<2> is an alkyl having up to four carbon atoms; R<3> is an alkyl having up to six carbon atoms; p is an integer of 1 to 3; q is an integer of 1 to 10; M is a metal ion having a valence of 3 or 4; and r is an integer of 3 or 4 according to the valence of M, provided when each compound contains more than one group of R<1>, R<2>, or R<3>, then these may be the same or different. This material forms a vitreous coating film which has sufficient flexibility, is excellent in the control of film thickness in a region of the order of micrometer, and rapidly cures to give a cured film having high adhesion to the substrate and excellent resistance to organic solvents. The invention also relates to a coating method using said material and to a coater.
