Abstract

Procedure for obtaining organosilicic adhesive compositions, inert with respect to the materials to be assembled, immediately adherent to olios by simple contact at room temperature, characterized in that by purchasing by mixing by weight: 40 to 70% of an organopolysiloxane resin A, formed by of formulas SiO2 and R3SiO0,5 in this last formula the symbols R, identical or different, represent aliphatic radicals chosen from among the methyl, ethyl, vinyl radicals, 70% being at least of these aliphatic radicals, methyl radicals, and the ratio from the number of motifs R3SiO0.5 to the number of motifs SiO2 is in the range of 0.45/1 to 0.9/1; 30 to 60% of a diorganopolysiloxane polymer B, terminated at each end of the chain by a hydroxyl group, with a viscosity of 100 to 10,000,000 cPo at 25ºC, formed essentially by my succession of motifs of formula (R') 2SiO in which the symbols R', which may be identical or different, represent hydrocarbon radicals chosen from among the methyl, ethyl, vinyl, phenyl radicals, at least 80% of these hydrocarbon radicals are methyl radicals; 0.3 to 5% with respect to A and B of an organic peroxide and heat the mixture thus formed to a temperature comprised between 80 and 200º for a sufficient period of time to obtain satisfactory adhesiveness.
