| abstract |
The invention is directed to a hydrogel forming composition comprising at least one water-soluble (meth)acrylic compound, at least one free radical initiator, at least one catalyst for free radical formation, and water, wherein the at least one catalyst for free radical formation is an amine compound of formula (I). The invention is also directed to a multiple-component composition, to a hydrogel, to use of the hydrogel forming composition for sealing of constructions, tunnels, or mines or for soil stabilization, to a method for sealing and/or filling of cracks, voids, flaws and cavities in a building structure, and to a use of at least one tertiary amine compound for reducing the gelling time of a hydrogel forming mixture. |
