  • Polyurethane compositions with NCO and silyl reactivity
    Publication number: 20060205859
    Abstract: The invention relates to polyurethanes or polyureas, which carry both silyl groups and NCO groups and which can be produced while using asymmetric diisocyanates and substituted alkoxy aminosilanes, to preparations that contain reactive polyurethanes or polyureas that carry silyl groups, to methods for producing these reactive polyurethanes or polyureas that carry silyl groups, and to the use thereof.

  • Binding agents and binding agent compositions containing alkoxy silyl groups, methods of production and use
    Patent number: 7067563
    Abstract: A binder which is a graft polymer bearing at least two alkoxysilyl groups of the formula —Si(R1)m(OR2)3-m in which R1 and R2 are independently linear or branched alkyl groups containing 1 to 6 carbon atoms and m is an integer of 0 to 2. The graft polymer has graft branches on a graft base. The graft polymer contains at least 0.5% by weight, based on the graft base, of graft branches.

  • FOAM PLASTIC FROM DISPOSABLE PRESSURIZED CONTAINERS
    Publication number: 20040214910
    Abstract: A composition useful for the production of foam plastics from disposable pressurized containers is provided. The composition comprises at least one polyisocyanate or isocyanate prepolymer, at least one catalyst for the reaction of the isocyanate group with the OH group, at least one blowing agent and at least one foam stabilizer. One day at the latest after application from said disposable pressurized container, the residue of said composition left in the pressurized container has a diisocyanate monomer content of less than 5.0% by weight, based on the residual contents of the emptied container.

  • Composition for producing light plaster, production of the foaming agent used therefor and its use
    Patent number: 6162839
    Abstract: A composition for producing light plaster contains as main constitutive elements particles of plaster in anhydride or hemihydrate form and at least one foaming agent. The composition is characterized in that the foaming agent generates gas after a delay of 1 minute to 24 hours and constitutes 0.1 to 50% by weight of the total dry mixture. Also disclosed is the use of said composition to produce in-situ cellular plastic and low density plaster moldings.
