What is disclosed are thermosetting epoxy resin compositions containing block siloxane copolymers which are used to induce low internal stress in the cured compositions and to provide coefficients of thermal expansion more closely aligned with the coefficients of thermal expansion of the substrates being molded therewith.

Thermosetting epoxy resin compositions

A jointed watertight, airtight, elastomer-coated material is described. The material consists essentially of a first elastomer-coated fabric material and a second elastomer-coated fabric material, said second material being overlaid at an edge over an edge of the first material. The overlaid portion of each material is laminated to the other with a pressure-sensitive adhesive intercalated between the two materials. The laminated portion is further bound with a fastener which penetrates across the laminated portion in an up-and-down manner. Typical fasteners are thread, rivets, or bolts. The jointed material can be further bound by a tacky tape which is adhered on the bound portion of one material and the unbound portion of the other material, covering the joint between the edges of the two materials. The jointed waterproof, airtight, elastomer-coated fabric material is particularly useful for air-supported structures.

This invention describes a water-impermeable elastomer-coated cloth composite in which the end sections of mutually adjacent elastomer-coated cloths are overlapped and sewn together in such a way that the thread passes up and down through this overlapped section. After a seam is sewn together, it is covered by an adhesive tape applied so that it extends over the sewn section of the seam and onto the portion of each section of the cloth beyond the sewn section to form a strong, watertight, airtight composite.

What is disclosed is an improved heat curable molding composition which has increased flowability in the mold. The improvement is gained by the use of a fine, spherical noncrystalline filler along with the normal molding compound fillers.

Heat curable molding composition

An improved thermosetting silicone resin molding composition characterized by consisting essentially of 100 parts by weight of organopolysiloxane resin having organic radical: Si ratio of 1.0:1 to 1.7:1 and containing at least 0.2% by weight of silicon-bonded hydroxyl groups, organohydrogenpolysiloxane containing at least one silicon bonded hydrogen atom in each molecule thereof, said organohydrogenpolysiloxane being in such an amount that the number of the hydrogen atoms per hydroxyl group in said organopolysiloxane is between 0.001 and 0.30, 0.01 to 15 parts by weight of organotin oxide, and 50 to 700 parts by weight of an inorganic filler.
