Abstract: A composition for sealing joints, penetrations and other leaks in particular in the construction field, including at least one ethylenically unsaturated, radically polymerizable water-soluble compound, at least one radical initiator, water and at least one corrosion inhibitor including at least one phosphate. The corresponding composition has a corrosion-inhibiting effect with respect to metal.

Abstract: A method for connecting sealing strips, includes at least one latent alkyl borane and is substantially free of decomplexing agent for the latent alkyl borane, to a sealing-strip substrate (1), applying a radical-curing adhesive to the sealing-strip substrate (1) pre-treated with the latent alkyl borane, bringing the sealingstrip substrate (1) in contact with a sealing-strip substrate (2) in such a way that the radical-curing adhesive is arranged between the two substrates, and allowing the radical-curing adhesive to cure, a composite structure thus being fonned. The method for adhesively bonding sealing strips based on elastic and thennoplastic substrates, such as EPDM or SBR, but also for adhesively bonding PVC sealing strips. Sealing strips adhesively bonded accordingly are characterized by favorable resistance of the adhesive to alkaline media, wherein conventional adhesives can be used which have optimized properties with regard to the storage stability, the open time, and the curing time thereof.

Abstract: A multiple-component composition that can be used for producing a corrosion inhibiting (meth)acrylic hydrogel. The multiple-component composition including at least one water soluble (meth)acrylic compound, at least one free radical initiator, at least one benzoate, and optionally at least one catalyst for free radical formation. A method for producing a hydrogel, to a hydrogel obtainable by the method, to a (meth)acrylic injection material, and to a method for sealing cracks, voids, flaws and cavities in building structures.

Abstract: A polyether having a functional group that is reactive to isocyanate with at least one polyisocyanate, which has an average isocyanate functionality in the range of 2.4 to 3.5, and at least one vinyl compound, which has a functional group that is reactive to isocyanate, wherein the molar ratio of polyether to vinyl compound lies in the range of 3:1 to 1:3 and the ratio of the sum of the molar quantities of polyether and vinyl compounds to isocyanate groups lies in the range of 1.5:1 to U.5. Corresponding vinylterminated prepolymers have the advantage of low visocity together with good water solubility and therefore can be used advantageously for applications as injection agents.
