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.
