Abstract:
The bond strength between solid inorganic materials, such as glass, and certain organic resins, such as epoxies, is strengthened by treatment of the solid with a mixture of a water soluble zirconyl salt and a gamma-trialkoxysilylpropylamine prior to the formation of the bond.
Abstract:
A SILICONE-CARNAUBA WAX COPOLYMER IS DISCLOSED. THE SILICONE-CARNAUBA WAX IS A COPOLYMER OF AN ORGANOSILICON COMPOUND AND CARNAUBA WAX BONDED TOGETHER BY PREDOMINANTLY ETHER LINKAGES. THE SILICONE-CARNAUBA WAX COPOLYMERS ARE WAXES USEFUL AS LIPSTICKS, FLOOR WAX, FURNITURE WAX AND LIKE.
Abstract:
AMINOSILANES SUCH (CH3O)3SI(CH2)3NH(CH2)2NH2 ARE MIXED WITH ALDEHYDES SUCH AS FORMALDEHYDE TO GIVE WATERSOLUBLE REACTION PRODUCTS. THESE PRODUCTS ARE USEFUL AS BONDING AGENTS BETWEEN ORGANIC RESINS AND SILICEOUS AND OTHER SURFACES.

1,180,601. Alkoxyalkylarylsilanes and siloxanes. DOW CORNING CORP. 10 Jan., 1967 [1 Feb., 1966(2)], No. 1325/67. Headings C3S and C3T. The invention comprises silanes of the general formula XnR 1 3-n SiQ m ArCH 2 OR and condensates thereof which are polymers of the average general formula, where R is a lower alkyl radical with 1-4 C atoms, Q is an alkylene radical, Ar is a divalent arylene radical or a divalent aryl ether radical, X is a hydroxyl radical or a hydrolysable atom or radical, R 1 is a monovalent hydrocarbon radical with not more than 18 C atoms, n is 1 to 3, m is 0 or 1, a has an average value of 1 to 3; b an average value of 0 to 2; (a + b) is from 1 to 3. The silanes of the invention may be prepared by three methods: (1) Reacting a silane of the general formula with RONa in a solvent such as methanol; (2) reacting a silane of the general formula X n R 1 3-n SiCl with a Grignard reagent prepared from ROCH 2 ArQ m ,Br; and (3) reacting X n R 1 3-n SiH with ROCH 2 ArQ 1 in the presence of chloroplatinic acid, where Q 1 is a monovalent aliphatic hydrocarbon radical which contains one unsaturated group. Preferably the silane comprises R 1 = Me, R = Me, X = OMe or Cl, Ar = C 6 H 4 , n = 3 and Q = -CH 2 -CH 2 -, e.g. CH 3 OCH 2 C 6 H 4 CH 2 CH 2 Si(OCH 3 ) 3 , which is prepared from ClCH 2 (CH 4 CH 2 CH 2 Si(OCH 3 ) 3 and NaOMe (method 1) in one of the examples. A silane CH 8 OCH 2 C 6 H 4 Si(OCH 3 ) 3 , having the further preferred characteristics n = 3, X = Cl or OMe, m = 0, Ar = C 6 H 4 , R = Me, is prepared by method 1 from the corresponding bromide and NaOMe and is hydrolysed to a siloxane of the unit formula The condensates are prepared by conventional hydrolysis of the silanes.
