Abstract: A process for assembling an airbag for use in vehicle applications is disclosed. The airbag has a seam made from two or more different materials (102, 104). The combination of the materials and the process for assembling the airbag minimize the need for sewn seams.

Abstract: An “all-in-one” spacer and seal useful in insulating glass units is based on silane-functional, organic polymer which preferably has a low permeability (e.g., curable polyisobutylene or curable butyl rubber) technology. This chemically crosslinking (curing) flexible thermoset spacer and seal offers a solution to overcome the current shortfalls of commercially available thermoplastic spacer materials. When used as an edge-seal in an Insulating Glass unit, the cured product of the composition performs the functions of sealing, bonding, spacing, and desiccating.

Abstract: A composition for preparing a pressure sensitive adhesive contains (A) a hydroxyl-functional polydiorganosiloxane polymer, (B) a hydroxyl-functional polyorganosiloxane resin, and (C) a solvent. A continuous method for producing the silicone pressure sensitive adhesive is performed by mixing the composition while heating the composition at a temperature above the vaporization point of the solvent and removing essentially all volatile species in an apparatus with a residence time sufficient for bodying ingredients (A) and (B). A devolatilizing twin-screw extruder is useful in the method.

Abstract: A room temperature vulcanizing (RTV) silicone composition curable in the presence of moisture with rapid development of green strength. The RTV silicone composition comprises (A) 0 to about 85 weight percent polydiorganosiloxanes comprising on average at least 1.2 chain terminations per molecule selected from the group consisting of hydroxysilyl groups and alkoxysilyl groups; (B) about 10 to 95 weight percent polydiorganosiloxanes comprising on average at least 1.

Abstract: An oxime curable silicone sealant composition with good oil resistance can be formulated, using calcium carbonate filler with higher water content than previously known to be useful. The sealant formulation is adjusted to accommodate higher water content by adjusting the ketoximosilane crosslinker level. The correct amount of crosslinker is determined by the hydroxy content present from both the silanol on the base polymer and the water content of the filler.

Abstract: The invention relates to a RTV silicone composition having increased hot oil resistance upon curing. The RTV silicone composition comprises a polydiorganosiloxane, an acyloxy-functional crosslinker, a metal salt of a carboxylic acid catalyst, a filler, and a metal acetate. In a preferred embodiment a metal acetylacetonate is also added.

Abstract: A process of making a polydiorganosiloxane-silica foundation mixture from a free-flowing, powdered, surface-modified, reinforcing silica-polydiorganosiloxane concentrate used to make, for example, RTV silicone sealant compositions which have non-sag properties. The foundation mixtures are made by combining, mixing, and heating a reinforcing silica filler and a diol surface modifying agent to a temperature of 20.degree. C. to <180.degree. C. using 0.05 to 0.5 parts by weight of the diol per one part by weight of the silica. Polydiorganosiloxane is added gradually to the resulting fluidized filler over a time period of less than 10 minutes to obtain the free flowing powdered reinforcing silica-polydiorganosiloxane concentrate. The foundation mixture is obtained by massing the concentrate and adding more polydiorganosiloxane to obtain a mixture which has from 5 to 20 weight percent silica filler. The foundation mixtures have a plateau stress of >700 dynes/cm.sup.

Abstract: A process of making a pumpable, stable, polydiorganosiloxane-silica foundation mixture by mixing and heating a polydiorganosiloxane, a reinforcing silica filler, and a diol surface modifying agent at >50.degree. C. to <180.degree. C. using 0.05 to 0.5 parts by weight of the diol per one part by weight of the silica. The foundation mixture can be used to make RTV silicone sealant compositions which are non-sag.
