Adhesion of Photopolymer Materials to Glass and Ceramics: Silanisation, Hydroxylation, Moisture and Interfacial Fracture

Adhesion of a photocurable coating or bonded feature to glass or ceramic is governed by the declared inorganic composition, phase, finish and hydroxylated surface state together with the coupling layer, photocurable network, cure history, environment and test geometry. A nominally clean glass surface may carry adsorbed water, alkali-rich alteration, organic contamination or a previous silane layer. A ceramic label may conceal a silicate glass, glass-ceramic, zirconia-rich surface or multiphase oxide. These states are not interchangeable.

This review defines a qualification architecture that separates cleaning, hydroxylation, roughening and silanisation; verifies coupling-layer chemistry and organofunctional compatibility; distinguishes wetting and cross-cut response from interfacial fracture; and follows crack path under moisture and cyclic loading. The evidence supports paired surface, cure and mechanical measurements across UV-cured glass coatings, silane-treated glass-ceramics and adjacent epoxy/glass fracture studies. It does not establish a universal silane recipe, hydroxyl density, roughness, coupling-layer thickness, cure schedule, humidity limit, fracture threshold, acceleration factor or service-life claim.
