The present invention relates to multicomponent compositions that can be used to prepare corrosion inhibiting (meth) acrylic hydrogels. The multicomponent composition comprises at least one water soluble (meth) acrylic compound, at least one free radical initiator, at least one benzoate, and optionally at least one free radical-forming catalyst. The present invention also relates to a process for the production of hydrogels, hydrogels obtainable by this process, (meth) acrylic injection materials, and methods for sealing cracks, voids, flaws and cavities in building structures. |
