Impression material for dental use contg. polyether polymer - including poly:organo:hydrogen:siloxane, platinum catalyst, inorganic filler and antioxidant

摘要

An impression material contains (A) a polyether polymer with at least 2 alkenyl gps., (B) a polyorganohydrogensiloxane with at least 3 Si-linked H, (C) a Pt catalyst, (D) an inorganic filler, and (E) an antioxidant. USE/ADVANTAGE - A prod. obtd. by hardening the compsn. is claimed. The compsn. can be used for various impressions and mouldings, including dental impressions. The compsn. is hydrophilic, with low shrinkage on hardening. An accurate impression can be made in moist conditions, e.g. in the mouth.
