  • Patent number: 9228119
    Abstract: The present invention provides a two-component silicone composition including a component A including at least one polydiorganosiloxane P and a component B, wherein one of the two components A and B additionally includes at least one hydrophobic silica and the other of the two components additionally includes at least one additive selected from the group including polyamine, polyether, heteropolyether and polyetheramine. Application of an inventive composition is accompanied or immediately followed by a rise in the viscosity, such that the composition displays improved initial strength and a lower propensity to slump.
    Type: Grant
    Filed: September 29, 2011
    Date of Patent: January 5, 2016
    Assignee: SIKA TECHNOLOGY AG
    Inventors: Matthias Büttner, Alexander Djurdjevic
  • Patent number: 8686094
    Abstract: A two-component silicone composition that includes a component A that includes i) at least one hydroxyl-group-terminated polydiorganosiloxane P; ii) at least one catalyst K for the cross-linking of polydiorganosiloxanes; and a component B that includes i?) at least one cross-linking agent for polydiorganosiloxanes. Compositions can be used as adhesives, sealants, coatings or as casting compounds and can be distinguished by a very long shelf life.
    Type: Grant
    Filed: May 19, 2011
    Date of Patent: April 1, 2014
    Assignee: Sika Technology AG
    Inventors: Alexander Djurdjevic, Christin Hamann, Michael Böttiger
  • Patent number: 8618235
    Abstract: The present invention relates to silicone compositions which comprise at least one ketoximosilane-terminated polydiorganosiloxane and also at least one alkoxysilane. These compositions are neutrally crosslinking and combine a low odor with high adhesion and good storage stability.
