Kerr Permlastic is a polysulfide, condensation-cured, elastomeric impression material available in multiple viscosities. The Heavy Body formulation is designed for use in a tray, providing stiffness and rigidity while maintaining enough flow to capture precise margins and fine anatomical detail. It offers excellent tear strength, dimensional stability, and can be used in double-mix or copper-band impression techniques, and impressions can be electroplated. The standard package includes two 100g tubes of base, one 70g tube of catalyst, and a mixing pad.
