Effect of metal priming agents on bonding characteristics of an acrylic resin joined to SUS XM27 steel

Abstract

The purpose of the current study was to evaluate the effect of functional monomers contained in the primers on adhesive bonding of a steel alloy. SUS XM27 steel was primed with one of the following materials; Alloy Primer, Estenia Opaque Primer, and V-Primer. The functional monomers in the primers were a phosphate (10-methacryloyloxydecyl dihydrogen phosphate; MDP) and a thione (6-(4-vinylbenzyl-n-propyl) amino-1,3,5-triazine-2,4-dithione, -dithiol tautomer; VTD) for Alloy Primer, MDP alone for Estenia, and VTD alone for V-Primer. The steel disks were bonded with an acrylic resin (Unifast Trad), and bond strength was determined. Of the three primers, both the Alloy Primer (33.3 MPa) and Estenia Opaque Primer (33.9 MPa) materials exhibited far better post-thermocycling bond strength than V-Primer (0 MPa). It can be concluded that the phosphate MDP is effective, whereas the thione VTD is ineffective for bonding SUS XM27 steel.

Comparative evaluation of metal priming agents applied for bonding of magnetic stainless steel with acrylic repair resin

“…The author speculates that the durable bond strength to XM27 steel is derived from interaction between the dihydrogen phosphate in the MDP and the passive chromium oxide film on the XM27 steel (21). Effectiveness of the MDP monomer in bonding stainless steel has already been reported (13,14,17,18). The results of the current study agree with those findings, although the composition of luting agents and adherends were not identical.…”

“…Although there are various adhesive systems for bonding stainless steel and related dental alloys (13)(14)(15)(16)(17)(18)(19), limited information is available about various primers, especially related to the chemical ingredients and functional monomers. The purpose of this study was to evaluate the effect of acidic priming agents on the bond strength and durability of an acrylic repair resin bonded to stainless steel.…”

Fixation of magnet assembly to denture base using alternative resins

“…All of the fixation resins used in this study have more porous structures as compared to the PMMA resin; thus, it would become unclean around the keeper [30][31][32][33][34] . However, less water absorption of the temporary filling materials and the photopolymerization denture relining resins was confirmed as compared to the others 35,36) .…”

“…Fixation strengths would depend on both the adhesive strength and the mechanical retention between the magnetic assembly and the fixation materials 29,30) . In the present study, application of a conventional metal primer and Super-Bond was examined to investigate the effectiveness of the adhesive strength.…”

Effects of alumina air-abrasion and acidic priming agents on bonding between SUS XM27 steel and auto-polymerizing acrylic resin

“…The adhesive bonding of magnetic steels have been reported in literature (4)(5)(6)(7)(8). Acidic primers proved to be effective in bonding various steels (4)(5)(6)(7)(8), whereas other compounds such as thione, were ineffective in bonding the XM27 steel (8).…”
