4-acryloxyethyltrimellitic-acid and 6-(4-vinylbenzyl-n-propyl)amino-1-3-5-triazine-2-4-dithiol

The purpose of the current study was to evaluate the adhesive performance of metal conditioners and a surface modification system when used for bonding between a prosthetic composite material and a titanium alloy.. Eight metal conditioners (Acryl Bond, All-Bond 2 Primer B, Alloy Primer, Ces II Opaque Primer, Eye Sight Opaque Primer, Metafast Bonding Liner, Metal Primer II, and MR Bond) and a bonding system (Siloc) were assessed. Cast disk specimens made of a titanium alloy (Ti-6Al-7Nb, T-Alloy Tough) were either primed with one of the eight primers or treated with the Siloc system and bonded with a light-activated prosthetic composite material (Artglass). Shear bond strengths were determined both before and after thermocycling (4 C-60 C, 60 s each, 20,000 cycles) for evaluation of the durability of the bonds.. The results showed that the Siloc-treated group recorded the greatest post-thermocycling bond strength, followed by the two groups conditioned with the Cesead II Opaque Primer and Alloy Primer agents, both of which contain an identical hydrophobic phosphate-methacrylate functional monomer.
