Abstract

A silicone rubber-forming composition, vulcanizable at room temperature, comprises (by weight) (1) 100 parts of a diorganosiloxane polymer of the formula ZO[R2SiO]nZ, wherein each R is a monovalent hydrocarbon or halogenated hydrocarbon radical, each Z is R or a hydrogen atom, n has an average value of at least 50 and the average R/Si ratio is 1,95 to 2,05, (2) 0,5 to 20 parts of a siloxane of the average formula RmHSiO3-m,/2 in which m has an average value between 0 and 2 (3) 0,1 to 5 parts of a condensation catalyst, and (4) 0,1 to 10 parts of a substance which is reducible by nascent hydrogen. In siloxane (1) R can be alkyl, alkenyl, cycloalkyl, aryl, alkaryl or aralkyl, with or without halogen substituents. Other ingredients specified are:-(3) dibutyl tin dilaurate and -maleate, zinc octoate, phenylmercuric acetate, metal chelates and oxides, boric and oleic acids and triethanol- and dibutylamines; (4) sulphur, selenium, tellurium and oxygen and compounds thereof, many examples of which are given. Fillers, e.g. mica dust, diatomaceous earth, C blacks, silicas (fume, aerogel and xerogel), asbestos, barium titanate, fibreglass floc, Fe2O3, ZnO, TiO2, MgO, ZnS, PbO, PbO2, Al2O3, CaCO3, and micronized slate and graphite, and antioxidants, pigments, &c., may also be added. In a typical Example (1) a mixture of sulphur, dibutyltindilaurate and tetraethylorthosilicate (as carrier) was added to a mixture of a hydroxy-terminated dimethylpolysiloxane and diatomaceous earth. Uses: for taking anatomical, and especially dental impressions. Specification 804,199 is referred to.
