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 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.
