A reactive resin contains at least one accelerator with high reactivity and at least one accelerator with low reactivity. A combination of at least one accelerator with high reactivity and at least one accelerator with low reactivity can be used in a reactive resin system. An accelerator composition can be used for a reactive resin system containing at least one accelerator with high reactivity and at least one accelerator with low reactivity.

Accelerator combination

A reactive amine accelerator is prepared by reacting a primary or secondary aromatic amine with a diglycidyl ether and an α,β-unsaturated carboxylic acid. The reactive amine accelerator can be used in a reactive resin, in particular based on an epoxy (meth)acrylate resin or a urethane (meth)acrylate resin. A reactive resin composition, in particular based on epoxy (meth)acrylate resin and urethane (meth)acrylate resin, which has an amine accelerator is useful. The amine accelerator is covalently incorporated into the polymer network.

Reactive amine accelerator, a reactive resin containing said accelerator, and the use thereof

A mixture includes at least two radically curable compounds as a backbone resin, and is useful in reactive resins. In particular, the mixture reduces the viscosity of such reactive resin-containing mixtures and thus the dispensing forces required for ejecting the reactive resin components produced therefrom. The mixture also increases the performance of the reactive resins containing such mixtures and of the reactive resin components produced therefrom. Further, said reactive resins and the reactive resin components thereof are useful for construction purposes, in particular for chemical fastening.

Mixture of radically curable compounds and use thereof

Branched urethane methacrylate compounds are useful as backbone resins for increasing the performance of a fastening material. Furthermore, reactive resins and reactive resin components containing such compounds are useful for chemical fastening.

Branched urethane methacrylate compounds and use thereof

Low viscosity urethane methacrylate compounds are used in a reactive resin and in a reactive resin component for construction purposes. The compounds are useful for lowering the viscosity of a reactive resin and for lowering the forces of extrusion of a reactive resin component or of a reactive resin system.

Reactive resins containing urethane methacrylate compounds, reactive resin components and reactive resin systems and use thereof

A method is useful for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the degradation of TEMPOL in mixtures with branched urethane resins.

Method for producing a TEMPOL-containing urethane resin composition having an improved storage stability

A reactive resin includes a vinyl ester resin as a base resin and an oligomeric itaconic acid ester as a reactive diluent.

Biogenic oligomers as reactive additives for the curing of reactive resins

A two-component mortar mass comprises a resin component (A), which contains at least one radically curable resin as a curable constituent, and a curing component (B), which contains a curing agent for the radically curable resin of the resin component (A). The radically curable resin can be obtained by reaction of an at least difunctional isocyanate with a hydroxy-functional silane and a hydroxy-functional, ethylenically unsaturated compound. The hydroxy-functional silane is the reaction product of a cyclic compound from the group of cyclic carbonates, lactones, and carbamates with a silane compound selected from the group of amino-functional, hydroxy-functional or mercapto-functional silanes.

Two-component mortar mass and use thereof

Disclosed is a method for producing vinyl ester urethane resins, in which a dianhydrohexitol-compound is reacted with a diisocyanate in the presence of a monomeric radically co-polymerizable compound as a solvent and the product is reacted with a hydroxy-substituted (meth)acrylate. As a result, vinyl ester urethane resins based on dianhydrohexitol-compounds and also based on renewable raw materials can be obtained in a simple manner with high yields. The resins are suitable as binding agents in chemical fixing engineering.
