Abstract
A cross-linking agent was added to increase the bonding strength of Superbond C & B by improving its cohesiveness. PMMA powder, which was copolymerized with 0.5%(w/w) neopentylglycol dimethacrylate as a cross-linking agent, was used for the preparation of Superbond C & B. The bonding of Superbond C & B to which the cross-linking agent had been added was then examined by the pull-out test using an alloy with different levels of surface roughness prepared by two surface-processing methods (polishing with #600 waterproof abrasive paper or 50μm sandblast processing).<BR>The results were as follows:<BR>1. Superbond C & B had a bonding strength of 205kgf/cm2 after polish processing of the alloy with #600 waterproof abrasive paper and 199kgf/cm2 after 50μEm sandblast processing. The t-test showed no significant difference between the two types of processing.<BR>2. Superbond C & B to which the cross-linking agent had been added showed a bonding strength of 285kgf/cm2 in the material processed with #600 waterproof abrasive paper and 347kgf/cm2 in that processed with 50μm sandblast processing.<BR>3. Among various combinations of bonding agents and surface processing methods, the combination of Superbond C & B with the cross-linking agent and 50μm sandblast processing showed the highest values under all conditions.
