Elastomeric impression materials and cleaning systems for residue removal
Abstract
A materials evaluation program was conducted to characterize castable resin compounds as suitable dimensional inspection aids. A fast curing dimethylsilicone based compound was selected as the best performer of the eleven compounds tested. Evaluation of physical properties revealed an inherent problem of particle adherence to metal surfaces tested. A cleaning study was conducted to determine the effectiveness of the solvent systems in removing particulate matter from test surfaces. Silicon residues which can adversely affect bonding characteristics of the metals were identified in cleaning study tests. One solvent system composed of alkylarylsulfonic acids, toluene, and dichloromethane, gave superior results in breaking down and removing these polymerized compounds.
