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

1 . A hybrid system for use as an adhesive, coating or paint, characterised in that 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.

2 . The hybrid system according to claim 1 as an adhesive for chemical fixing technology, especially for fixing anchoring means in drilled holes, which system includes a reaction resin based on α,β-unsaturated compounds, a reaction resin based on compounds that include CH-acidic methylene groups, and a primary amine.

3 . The hybrid system according to claim 1 in the form of a multi-component system, especially a two-component system.

4 . The hybrid system according to claim 1 in the form of a two-component kit.

5 . The hybrid system according to claim 1 , further including a catalyst.

6 . The hybrid system according to claim 1 in the form of a multi-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.

7 . The hybrid system according to claim 1 , wherein the reaction resin based on α,β-unsaturated compounds is a reaction resin which comprises or consists of an α,β-unsaturated compound that carries at least one fumarate, maleate, itaconate or acrylate group or preferably two or more thereof, such as an acrylic acid ester or acrylamide, for example a mono- or especially di-, tri-, tetra- or higher polyacrylate, especially selected from hydroxy-C 2 -C 10 alkyl-acrylate, such as hydroxyethyl, hydroxypropyl or hydroxybutyl 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 polyethoxy-triacrylate, 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 thereof, such as acid halides or active esters or from the reaction of polyester polyols with acrylic acid or reactive derivatives thereof, especially as just mentioned, or urethane acrylates (obtainable, for example, by reaction of isocyanates with an OH-group-containing acrylate, such as hydroxyethyl-, hydroxypropyl-, hydroxybutyl- or pentaerythritol-tri-acrylate, and polyester acrylate resins, for example tetrafunctional polyester acrylates); an acrylic-functional alkoxysilane or organopolysiloxane, such as acrylatomethyl-trimethoxysilane, -methyldimethoxy-silane, -dimethylmethoxysilane, -triethoxysilane or -methyldiethoxysilane, acrylamido-methyl-trimethoxysilane, -methyldimethoxysilane, -dimethylmethoxysilane, -triethoxy-silane, or -methyldiethoxysilane, -methyl-dimethylethoxysilane;
