    Abstract: A glass slide is rendered water-repellent by coating with a diaminotriazine siloxane oil having the formula drying, and baking at 130 DEG C. for about 3 hours (Example 9). Reference has been directed by the Comptroller to Specifications 684,296, 769,498 and 795,894.ALSO:Silylalkylaminotriazine compounds and corresponding polysiloxanes containing the grouping are prepared by reacting an aminoalkyl silicon compound containing the group [H2N(CH2)aSi­] where a is at least 3, with a triazine of the formula where Y1 is halogen, and Y2 and Y3 are the same or different and represent halogen, or an OH or NH2 or NHR group in which R is an alkyl or aryl group or an -HN(CH2)aSiR1bX3-b group in which R1 is an alkyl, aryl or aralkyl radical, X is alkoxy and b is 0 to 3. The starting organosilicon compounds are disclosed in Specifications 882,054 and 882,069. The triazine may be tri-substituted, the halogen atoms being replaced successively at 0 DEG C., 30 DEG -60 DEG C. and 90 DEG C. respectively. Hydrogen halide acceptors are preferably present. When Y1, Y2 and Y3 are originally halogen, two of them may be left as such if only 1 mole of silicon compound is used, or they may be reacted with water, ammonia or primary amines. With water, hydrolysis will also occur, producing a siloxane. The products containing one or two amino groups attached to the ring may be condensed with formaldehyde to form melamine-type resins, or they may be compounded with curable melamine resins. The examples describe the preparation, inter alia, of: 2,4-dichloro- and 2,4-diamino-6-(3-triethoxysilylpropylamino)-triazine; 2,4,6-tri-(3-triethoxysilylpropylamino)-triazine and the siloxane derived therefrom; the siloxane having the formula and the siloxane having the formula Uses: Sizes for fibrous materials, waterrepellents, modifiers for other polysiloxanes, coatings, grease-modifiers, moulding compositions, plasticesers, melamine-type resins. Reference has been directed by the Comptroller to Specifications 684,296, 769,498 and 795,894.
