Patent GB-650993-A (GB)
Title: Improvements in and relating to methods of curing of hydrocarbon-substituted polysiloxane resins
Filed: 1948-09-10
Abstract: Liquid hydrocarbon substituted siloxane resins in which the average number of hydrocarbon groups attached to the Si. atoms is between 1 and 2 are hardened to the infusible state by heating them with 0.05-5 per cent by weight of the resin, of a compound of formula (R)4N-OR1 where R represents hydrocarbon or hydroxy-substituted hydrocarbon radicals and R1 represent hydrogen or an acyl radical.  There are specified as curing catalysts: tetraethyl-, phenyl trimethyl-, diethyl dimethyl-, tetraphenyl-, tetratolyl-, tetramethanol-, tetrabutanol-, tetra-(2-hydroxy propyl)-ammonium hydroxide, formate or propionate.  They may be added dissolved in acetone, tetrahydrofurane, alcohols, and glycol ethers.  Curing is effected by heating at 905-240 DEG  C. for 15 minutes to 3 hours. Examples describe the properties of glass tapes dipped into solutions of the curing catalysts and resins and heat hardened at various temperatures.  Siloxane resins which may be hardened according to the above procedure are described in Specifications 542,655, 544,143, [Group XXII], 551,649, 548,192 and 548,911. With the addition of fillers, e.g. titanates, mica, conductive materials, the siloxanes may be moulded and cured to form laminates, resistors, or conductors. The Specification as open to inspection under Sect. 91 includes curing catalysts in which the radical R1 is a hydrocarbon, e.g. tetraethyl or ethanol ammonium ethoxide as exemplied in Example 2 (Cancelled), where a resin obtained by co-condensation of a mixture of methyltrichloro, dimethyldichloro, phenyltrichloro and diphenyldichlorosilanes is dissolved in toluene and mixed with 0.5 per cent benzyl trimethyl ammonium butoxide is used to impregnate glass tapes which give a tack-free surface when heated for 1 hour at 95 DEG  C.  Similarly a liquid resin obtained by hydrolysis and condensation of a mixture of methyltrichloro, phenyl trichloro and dimethyl dichlorosilanes and containing 0.1 per cent benzyl trimethyl ammonium butoxide remains stable at room temperatures but is cured to the infusible state by heating for 1 hour at 95 DEG  C.  This subject-matter does not appear in the Specification as accepted.
