Coating material for forming vitreous coating film, method of coating with the same, and coater

摘要

A glassy-film-forming coating agent comprising compounds represented by the following general formulae (1), (2) and (3): R<1>pSi(OR<2>)4-p R<2))2)qOR<2> M(OR<3>)r wherein R<1> is a polymerizable organic group, R<2> is an alkyl group having not more than 4 carbon atoms, R<3> is an alkyl group having not more than 6 carbon atoms, p is an integer of 1 to 3, q is an integer of 1 to 10, M is a trivalent or tetravalent metal ion, and r is an integer of 3 or 4 corresponding to the valence of M, provided that, when one of the compounds contains two or more R<1>s, R<2>s or R<3>s, they may be the same or different; a coating method and a coating system using the same. The present invention provides a coating agent useful for forming a glassy film which has sufficiently high flexibility and which hardens rapidly with its thickness in the order of microns being well controlled, the hardened film showing high adhesion to a substrate and excellent organic solvent resistance. The present invention also provides a glassy-film-coating method and system using this coating agent.
