  • Adhesives having improved chemical resistance and curable silicone compositions for preparing the adhesives
    Patent number: 7521125
    Abstract: This invention relates to a composition that can be cured to form an adhesive. The adhesive is useful in the electronics industry. The composition is prepared by mixing components including: (I) a polyorganosiloxane having an average of at least two terminally-unsaturated organic groups per molecule, (II) an organohydrogenpolysiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule, (III) a hydrosilylation catalyst, (IV) a fluoroorganosilicone having at least one functional group reactive with component (I), component (II), or both, (V) an unsaturated ester-functional compound, and (VI) an adhesion promoter. The composition may also include one or more optional components selected from (VII) a void reducing agent, (VIII) a pigment, (IX) a filler, (X) a cure modifier, (XI) a rheology modifier, and (XII) a spacer.
    Type: Grant

  • Silicone coated textile fabrics
    Patent number: 6354620
    Abstract: A curable silicone-based coating composition, curable to a flexible coating at a coat weight of up to 15 g/m2 when cured, comprises an organopolysiloxane polymer having at least two silicon-bonded olefinically unsaturated hydrocarbon substituents, alkoxy groups or hydroxyl groups and having a degree of polymerization of no more than 150, a cross-linking organosilicon material having at least 3 silicon-bonded reactive groups and a catalyst. The coating composition optionally contains non-reinforcing filler but contains no more than 3% by weight of reinforcing filler. The coating is preferably used on a textile fabric that has an elastomeric coating on it, and reduces friction. It is particularly useful for airbags.
