Abstract

A room-temperature-vulcanizing siloxane composition comprises (by weight): 100 parts of at least one siloxane homopolymer and/or at least one copolymer of the formula R1R2SiO[R2SiO]xSiR2R1 in which each R is a monovalent hydrocarbon or halo-hydrocarbon radical (saturated or unsaturated), each R1 is H, an alkoxy, aryloxy or hydroxy radical and x has an average value from 50 to 10,000, with 0,05 to 2,0 parts of (a) at least one aminosilane of the formula R11nSi[NY2]4-n and/or (b) an aminosilazane of the formula <FORM:0905364/IV(a)/1> in which each R11 is an alkyl, aryl, or aralkyl radical, each Y is H or an alkyl or aralkyl radical, n is 0 or 1, a is 2 or 3,b is 0 or 1, c is 1 or 2 and m is at least 1. The compositions may also contain fillers, e.g. basic fillers such as ZnCO3, ZnO, CaCO3, CaO, MgCO3 and MgO, which also act as curing accelerators, and inert fillers, such as diatomaceous earth, quartz flour, glass fibres, silica aerogels and fume silica, pigments flavourings and essential oils. The compositions can be moulded, extruded, &c., for a short period of time and then be exposed to atmospheric moisture to effect vulcanization and cure. In a typical Example (1) 0,5 pt. of MeSi(NBu2)3 was milled with 100 pts. of a hydroxy-terminated dimethyl polysiloxane of 10,500 cs. viscosity, and poured into a glass cup; the mixture vulcanized within four hours at room temperature and at a relative humidity of 65% to form a silicone rubber. Uses: As joint sealants, dental stoppings, electrical insulation, adhesives for silicone rubber, silicone rubber coatings and as fabric and paper impregnating lacquers.
