| abstract |
The present invention is directed to multi-component compositions that can be used to produce corrosion inhibited (meth) acrylic hydrogels. The multi-component composition comprises at least one water soluble (meth) acrylic compound, at least one radical initiator, at least one benzoate and optionally at least one catalyst for free radical formation. . The invention is also directed to methods of producing hydrogels, hydrogels obtainable by this method, (meth) acrylic injection materials, and methods of sealing cracks, voids, crevices and cavities in architectural structures. |
