Cure material from liquid polythiopolymercaptan polymers for dental impression taking

摘要

The present invention is concerned with improved dental semi- solid or paste-like elastomeric materials which have the capability of precise surface detail reproduction at ambient and body temperature. Such materials are prepared by treating liquid polysulfide with a synergistic accelerator system comprising a metallic peroxide, e.g., zinc peroxide, 2, 2' dithiobisbenzothiazole and 2-mercaptobenzothiazole.
