Dental Kerr Permlastic Regular Polysulfide Impression Material Base & Catalyst
Kerr Regular Permlastic
Permlastic is a rubber base impression material available in three viscosities:
1. Light body is excellent for inlay and fixed bridge impressions
2. Regular body is recommended for partial- or full-denture impressions
3. The denser viscosity of heavy body results in optimum compression of the light body in a double-mix or copper-band impression.
