PURPOSE To evaluate the effects of carboxylic and phosphate functional monomers on the bond strength and durability of an acrylic resin joined to a magnetizable stainless steel and its component metals. MATERIALS AND METHODS Disk specimens (10 and 8 mm in diameter and 2.5 mm thick) were prepared from SUS XM27 stainless steel, high-purity iron, and chromium metals. The specimens were ground with abrasive paper, and divided into an unprimed control group and 4 groups primed with: 1. Alloy Primer (thione and phosphate); 2. Estenia Opaque Primer (phosphate); 3. Mr. Bond (aliphatic carboxylic acid); or 4. Super-Bond C&B Liquid (aromatic carboxylic anhydride). The disks were bonded with tri-n-butylborane (TBB)-initiated resin, and the shear bond strengths were determined both before and after thermocycling (20,000 X, 5°C - 55°C). The debonded surfaces were analyzed using Xray diffraction (XRD). RESULTS The Alloy Primer and Estenia Opaque Primer materials containing 10-methacryloyloxydecyl dihydrogen phosphate (MDP) effectively bonded the steel (30.3 to 32.4 MPa) and iron (33.6 to 34.8 MPa), whereas the four acidic primers bonded chromium (24.6 to 32.3 MPa). X-ray diffractometry detected corroded iron at the debonded interface. CONCLUSION Bearing in mind the limitations of the present study, the use of two primers with MDP is recommendable for bonding SUS XM27 steel with TBB-initiated resin. Iron was considered to be a corrosive factor at the adhesive interface, although the associated bonding characteristics were adequate.
