Abstract

A moisture-curable siloxane having the formula <FORM:1089229/C3/1> wherein each R is a monovalent hydrocarbon (h.c.), halo-h.c. or cyanoalkyl radical, R1 is H or an alkyl or halo-alkyl radical of 1 to 4 C atoms, R11 is a saturated or unsaturated h.c. radical with or without halo-or cyano-substituents, and n is an integer such that the viscosity of the polymer is from 500 to 500,000 cps. at 25 DEG C., is generally made by reacting an OH-terminated organopolysiloxane liquid with the product obtained by reacting a tetracycloxysilane with the desired alcohol, the product being mainly R11OSi(OOCR1)3 with varying amounts of (R11O)2Si(OOCR1)2 and unreacted Si(OOCR1)4. The reaction of the silane product and the siloxane is best effected at 95 DEG to 100 DEG C. under anhydrous conditions. Dry fillers, e.g. silica (fume, precipitated or aerogel), diatomaceous earth, crushed quartz, TiO2, Fe2O3, ZnO, asbestos and fibrous glass, colouring agents, dielectric materials, e.g. graphite, and other additives, may be added. Resinous siloxanes may be added either to improve adhesiveness or to decrease elasticity, and liquid siloxanes may be added as plasticizers. In a typical Example (1), MeOSi(OAc)3 was reacted with an OH-terminated siloxane liquid at 95-100 DEG C. in a dry nitrogen atmosphere to yield a viscous material which formed a tack-free rubbery surface within 10 minutes after exposure to atmospheric conditions. Uses.-In mould making, coating operations and for caulking.
