A composition comprising:

• a) one or more film forming resins having at least one functional group capable of polymerization;
• b) one or more adhesion promoters comprising compounds containing one or more unsaturated groups capable of free radical polymerization and one or more trialkoxy silane groups;
• c) one or more fillers capable of imparting abrasion resistance to the composition when polymerized;
• d) one or more compounds which is reactive with the film forming resin which also contains at least one acidic moiety;
• e) i) one or more compounds comprising a siloxane backbone and one or more active hydrogen groups capable of reacting with a functional group on a glass bonding adhesive;
• and, ii) A) one or more second adhesion promoters comprising one or more silicon, titanium, zirconium, aluminum, or metal containing compounds:
• ii) B) organic materials having reactive groups which contain one or more melamine units and unsaturated groups which polymerize when exposed to free radicals;
• or mixtures of ii) A) and ii) B);
• f) one or more reactive diluents capable of reacting with the film forming resin;
• and
• i) one or more catalysts or initiators capable of initiating polymerization of the film-forming resin;
• wherein the functional groups capable of polymerization of the film-forming resin polymerize when exposed to irradiation and the composition further comprises.
