PRIMED INORGANIC SUBSTRATES OVERCOATED WITH CURABLE PROTECTIVE COMPOSITIONS

摘要

Primer compositions for adhering overcoatings derived from in situ polymerizations of uncured monomers onto inorganic substrates are disclosed. These primer compositions when coated on a substrate and included in a layered structure comprise at least one non-amino- or non-amido-containing silane, at least one of certain metal esters, and preferably an acidic material. The overcoatings are derived from epoxy and vinyl monomers which require a superior level of adhesion. The primed and overcoated substrates of the present invention provide articles having protective or decorative surface layers.
