摘要

Improving the adhesion of a two-component chemical mortar mass with a resin component (A) comprising at least one radically curable, ethylenically unsaturated compound (a) as a curable component, and a separately arranged hardener component (B) comprising a curing component (a) for the resin of the resin component (A), to inhibit the reaction, on the surface of a wet drill hole in a mineral subsurface, comprises treating the surface of the wet drill holes with methacryloxy alkylalkoxysilane before introducing the mortar mass. An independent claim is also included for a solution for carrying out the above mentioned the method, comprising a 50-100% solution of methacryloyloxy alkyltrialkoxysilane in (meth)acrylic acid ester comprising hydroxypropyl (meth)acrylate, butanediol-1,2-di(meth)acrylate, trimethylolpropane tri(meth)acrylate, 2-ethylhexyl (meth)acrylate, phenylethyl (meth)acrylate, tetrahydrofurfuryl (meth)acrylate, ethyl triglycol (meth)acrylate, N,N-dimethylaminoethyl (meth)acrylate, N,N-dimethylaminomethyl (meth)acrylate, 1,4-butanediol di(meth)acrylate, acetoacetoxyethyl (meth)acrylate, 1,2-ethanediol di(meth)acrylate, isobornyl (meth)acrylate, diethyleneglycol di(meth)acrylate, methoxy polyethyleneglycol mono(meth)acrylate, trimethylcyclohexyl (meth)acrylate, 2-hydroxyethyl (meth)acrylate, dicyclopentenyloxyethyl (meth)acrylate, tricyclopentadienyl di(meth)acrylate, bisphenol-A-(meth)acrylate, novolac epoxy di(meth)acrylate, di-[(meth)acryloyl-maleoyl]-tricyclo-5.2.1.0.2.6-decane, dicyclopentenyloxyethyl crotonate, 3-(meth)acryloyloxymethyltricylo-5.2.1.0.2.6-decane, 3-(methyl)-cyclopentadienyl (meth)acrylate or dodecyl (meth)acrylate.
