The present invention provides a glass fiber strand comprising at least one glass fiber at least partially coated with a sizing composition prepared from ingredients comprising; at least one starch; at least one lubricant; and at least one silane coupling agent comprising: [((R1)bY)aR23-aSiR3]2NX, wherein R1 and R2 are each monovalent radials; R3 is a divalent linking group; a is 1 to 3; X is (R4)bZC(═O)CH(Q)CH(Q)—, wherein Z is CH2, O, S or N, Q is H, alkyl, aryl, alkaryl, or C(═O)ZR4 and R4 is a hydrocarbon moiety of one to twenty carbon atoms, hydrogen, a silyl group or an organic polymer; Y is oxygen, nitrogen or sulfur; and b is 1 or 2 depending upon the valency of Y. In one particular embodiment of the invention, the silane in the aqueous sizing composition is (CH3)3COC(═O)CH2CH2N[CH2CH2CH2Si(OCH3)3]2.

Unsaturated imidosilanes which are essentially free of siloxanes are taught herein for use surface treatments for inorganic solid materials. Novel methods to make such silanes, which do not yield water or siloxanes as a by-product are also taught. Compositions consisting essentially of imidosilane treated inorganic solid materials, resinuous materials and optionally a free radical generator, especially glass fiber reinforced composites, are taught.

Fatty ethenoid acylaminoorganosilicon compounds have been found to enhance the surface properties of glass articles. The fatty ethenoid acylaminoorganosilicon compound can be applied as a coating to the glass article's surface either alone or in combination with dispersing agents and organic polymers and/or fatty acids.
摘要:
The invention is directed to an activated halo-containing aralkylsilanes possessing at least one hydrolyzable group bonded to a silicon atom and at least one halo functional group bonded to a carbon atom to which both the silicon atom and an aromatic group are covalently bonded. The invention is also directed to a process for making such a silane as well as its use in rubber compositions and articles containing such rubber compositions, such as tires.
摘要:
Epoxysilanes are provided which contain at least one epoxy group, at least one hydrolyzable silyl group and one or more linkages containing a carbonyl group bonded to heteroatoms selected from the group consisting of oxygen, sulfur and nitrogen with at least one such heteroatom being nitrogen, there being no such linkage in which both an epoxy group and hydrolyzable silyl group are directly or indirectly bonded to the same nitrogen heteroatom in the linkage.
