摘要： The present disclosure generally relates to a curable one part silicone composition. The curable one part silicone composition includes an organopolysiloxane compound having at least two unsaturated groups; an organohydrogenpolysiloxane compound having at least two Si—H groups; a catalyst for enabling the addition of the hydrogen atoms bonded to the silicone to the unsaturated group; and at least one surface treated particulate filler. The curable one part silicone composition is useful as a dental impression material. More particularly, the curable one part silicone composition including the surface treated filler extends storage stability of the dental impression material. The disclosure also provides methods of preparing such curable one part silicone composition.

摘要： Disclosed herein is a dental impression material that includes a two part addition curing silicone composition. The disclosed impression material contains a surfactant system composed of a fluorosurfactant and a fatty alcohol ethoxylate. The impression material disclosed herein exhibits improved storage stability than known systems using fluorosurfactants and silicone ether compounds.
