  • Patent number: 9334433
    Abstract: The current invention relates to a moisture-hardening composition that contains, in addition to a silane-functional polymer with end groups of formula (I), a reaction product that can be manufactured from an amino silane with primary amino groups and an alkene that is free of silane groups. The compositions are characterized by improved expandability with concurrent high reactivity, good adhesion characteristics, and high tear strength and are suited especially for use as elastic bonding substance or sealant.

  • Patent number: 7210276
    Abstract: The invention relates to a wooden floor, consisting of a hardenable adhesive (12) which is painted onto a floor base (10) in a continuous layer, and covering elements (16) consisting of wood or a wood material that are joined to the adhesive in its entirety by their surface (14) to be glued. According to the invention, the adhesive layer (12) has a thickness of 0.5 to 5 mm and the combined tension and shear strength of the adhesive (12), in its hardened state, is les than that of the floor base (10) and is at most 1.2 N/mm2, in order to obtain a floor covering with excellent dimensional stability.

  • Patent number: 4778845
    Abstract: A one-component adhesive and/or sealing mass which is stable and pumpable at temperatures up to 30.degree. C. containsat least one prepolymer on the basis of a polyurethane, which contains from 0.1 to 15 percent by weight, referred to the prepolymer, of free, reactive isocyanate groups, andat least one with heat activatable hardener.Thereby the stoichiometric ratio between said prepolymer and said hardener is chosen in such a way that only a partial cross-linkage is possible during heating said mass to temperatures from 60.degree. C. to 180.degree. C., and that a product is obtained having from high viscous to plastic characteristics.The inventive masses may be used for bonding and/or sealing of one or more materials of the same or different origin to a composite.
