Patent GB-707143-A (GB)
Title: Improvements in and relating to resinous organopolysiloxanes
Filed: 1951-01-31
Abstract: Liquid heat-convertible organo-polysiloxane resins are stabilized and bodied by dissolving the resins in a hydrocarbon solvent, mixing into the solution from 0.01 per cent. to 10 per cent. by weight of the resin of zinc oxide and heating the mixture at 100-200 DEG C. until the viscosity of the mixture is not less than 400 centipoises. During the heating further condensation occurs producing a small amount of water which is removed by a water trap.  After the heating the zinc oxide is preferably removed. Glycerine may be added to the bodied solution to assist filtration or glycerine may be added before filtration in which case the desired viscosity is obtained more quickly.  The bodied resins have a long shelf life and are suitable as varnishes giving baked films of superior craze resistance.  Before application cure accelerators may be added to the varnishes, e.g. those disclosed in Specification 597,834.  In examples: (1) 183 parts of methyltrichlorosilane, 312 parts of dimethyldichloro-silane and 509 parts of phenyltrichlorosilane were hydrolysed and condensed and the resulting resin dried and dissolved in petroleum spirit, mixed with a small quantity of zinc oxide and heated at 165 DEG C. for 4 hours.  The final viscosity was 550 centipoises.  (2) The resin solution of (1) was heated at 160-7 DEG C. with zinc oxide and glycerine for 6 hours with an increase in viscosity of the mixture from 15 c.p. to 950 c.p.  Titanium dioxide in amount equal to the resin solids was added and the mixture diluted to 63 per cent. total solids with petroleum spirit.  0.5 per cent. of the resin of zinc octoate was added, and the resulting paint sprayed on to a metal panel and baked for an hour at 200 DEG C.  The craze resistance of the film was compared with that of an unbodied resin varnish by heating at 260 DEG C.  The addition of 10 per cent. by weight of the titanium dioxide of zinc oxide to the bodied resin further improved the craze resistance.  (3) The solution of example (1) was heated with glycerine for 40 hours at 165-175 DEG C. to a viscosity of 65 c.p. and a paint made up as in (2); (4) The solution of (1) was heated for 40 hours at reflux temperature and a paint made up as in (2).  (5) The solution of (1) was heated with zinc oxide and glycerine and heated for 19 hours at 166-175 DEG C. to a viscosity of 550 c.p., and a paint made up as in (2).  The paints of examples (3), (4) and (5) were used to prepare baked films and the films compared for craze resistance.  In addition to titanium dioxide the Specification refers to glass fibres, cotton cloth, and asbestos fibres as fillers from which moulded goods may be obtained.  Dyes and pigments, e.g. lithopone and titanium dioxide are also referred to. Specifications 542,655; 544,143; 548,911; 548,912 and 551,649 also are referred to.
