Abstract

A hybrid system for use as an adhesive, coating or paint, wherein the hybrid system includes a) a reaction resin based on α,β-unsaturated compounds, b) a reaction resin based on compounds that include CH-acidic methylene groups, and c) a primary amine, and to related subject matter.

First claim

The invention claimed is:

1. A method for mortar-bonded fixing of anchoring elements in a hole or a crevice in a substrate, comprising introducing a hybrid system adhesive and an anchoring means one after the other or simultaneously or in a mixed form with partial introduction in each case, into a hole or crevice in a substrate, wherein the hybrid system includes as constituents a) a reaction resin based on α,β-unsaturated compounds, b) a reaction resin based on compounds that include CH-acidic methylene groups, and c) a primary amine and allowing the parallel reaction of constituents a), b) and c) to harden.

2. The method for mortar-bonded fixing of anchoring elements in holes or crevices according to claim 1 , comprising using a-introducing the hybrid system and an anchoring means one after the other or simultaneously into a hole or crevice in a substrate.

3. The method according to claim 2 , wherein the hybrid system is in the form of a two-component system.

4. The method according to claim 2 , wherein the hybrid system further includes a catalyst.

5. The method according to claim 2 wherein the hybrid system is used in the form of a two-component kit, wherein (i) constituents a) and b) are present in one component, while constituent c) is present together with a catalyst in a different component which is not capable of mixing in the stored state, it being optionally possible in each case for one or more further ingredients to be present; or
(ii) constituents a), b) and the epoxy moiety of an epoxy/tert-amine catalyst are present in one component, and constituent c) is present together with the tert-amine moiety of an epoxy/tert-amine catalyst in a different component, it being optionally possible in each case for one or more further additional ingredients to be present.

6. The method according to claim 2 , wherein, in the hybrid system, the reaction resin based on α,β-unsaturated compounds is a reaction resin-selected from the group consisting of hydroxy-C 2 -C 10 alkyl-acrylate, ethanediol diacrylate, 1,3-propanediol diacrylate, 1,4-butanediol acrylate, poly (butanediol) diacrylate, polybutadiene diacrylate, 3-methyl-1,5-pentanediol-diacrylate, 1,6-hexanediol diacrylate, diethyleneglycol diacrylate, tetraethyleneglycol diacrylate, tripropyleneglycol diacrylate, triethyleneglycol diacrylate, triisopropyleneglycol diacrylate, dipropyleneglycol diacrylate, neopentylglycol diacrylate, ethoxylated or propoxylated neopentylglycol diacrylate, tripropyleneglycol diacrylate, bisphenol-A-, bisphenol-F-, bisphenol-AF-or bisphenol-S-diglycidyl ether diacrylate, bisphenol-A-polyethoxydiacrylates, bisphenol-F-polyethoxydiacrylates, polyethyleneglycol diacrylates, polypropyleneglycol diacrylates, trimethylolpropane triacrylate, di-trimethylolpropane tetraacrylate, trimethylolpropane polyethoxytriacrylate, ethoxylated or propoxylated trimethylolpropane triacrylate, glycerol triacrylate, ethoxylated or propoxylated glycerol triacrylate, tris (2-acryloxyethyl) isocyanurate, pentaerythritol triacrylate, pentaerythritol monohydroxytriacrylate, pentaerythritol triethoxytriacrylate, pentaerythritol tetraacrylate, ethoxylated or propoxylated pentaerythritol tetraacrylate, ditrimethylolpropane tetraacrylate, dipentaerythritol pentaacrylate, dipentaerythritol polyhexanolide hexaacrylate, dipentaerythritol hexaacrylate, tris (hydroxyethyl) isocyanuratopolyhexanolide triacrylate, tris (2-hydroxyethyl)isocyanuratotriacrylate, tricyclodecanedimethylol diacrylate, esterdiol diacrylate, 2-(2-acryloyloxy-1, 1-dimethyl)-5-ethyl-5-acryloyloxymethyl-1,3-dioxane, tetrabromobisphenol-A-diethoxydiacrylate, 4,4-dimercaptodiphenylsulfide diacrylate, polytetraethyleneglycol diacrylate, 1,9-nonanediol diacrylate, 1, 10-decanediol diacrylate, dimethylolpropane tetraacrylate, cresol epoxyacrylates, novolak “poly” acrylate, acrylate-group-containing oligomers or polymers from the reaction of polyepoxides with acrylic acid or reactive derivatives which are acid halides or active esters or from the reaction of polyester polyols with acrylic acid or reactive derivatives thereof as just mentioned, urethane acrylates obtainable by reaction of isocyanates with an OH-group-containing acrylate selected from the group consisting of hydroxyethyl-, hydroxypropyl-, hydroxybutyl-or pentaerythritol-tri-acrylate, and tetrafunctional polyester acrylates); an acrylic-functional alkoxysilane or organopolysiloxane selected from the group consisting of acrylatomethyl-trim ethoxysilane,-methyldimethoxysilane,-dimethylmethoxysilane,-triethoxysilane or -methyldiethoxysilane, acrylamidomethyl-trimethoxysilane,-methyldimethoxysilane,-dimethylmethoxysilane, -triethoxysilane, or-methyldiethoxysilane,-methyl-dimethylethoxysilane; a polyester resin based on maleic, fumaric or itaconic acid or a respective anhydride thereof;
