发明名称 HEAT-CURABLE EPOXY FUNCTIONAL COMPOSITION AND TRANSPARENT HEAT-CURED CAUSTIC-RESISTANT HARD-COATINGS PREPARED THEREFROM
摘要 <p>A heat-curable composition comprises - from 25 to 65 % by weight of a mixture of epoxy-functional monomers, said mixture consisting of at least one polyfunctional epoxy monomer selected from monomers comprising from 4 to 8 glycidyl groups and/or cycloaliphatic epoxy groups, and at least one bi- or tri-functional epoxy monomer selected from monomers comprising two or three glycidyl groups and/or cycloaliphatic epoxy groups, - from 25 to 70 % by weight of at least one organic solvent selected from glycol monoethers, - from 2.5 to 5 % by weight, relative to the total weight of epoxyfunctional monomers (a) and (b), of at least one blocked strong acid catalyst, said heat-curable composition not containing any non-epoxyfunctional monomers, in particular not containing any acrylic, methacrylic or silane monomers.</p>
