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 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

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.

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 includes a resin component (A), which contains as curable constituent at least one radically curable resin, and a curing component (B) which contains a curing agent for the radically curable resin of the resin component (A), wherein the resin component (A) and/or the curing component (B) contain(s) as further constituent at least one inorganic additive. The inorganic additive contains a transition aluminum oxide having an average particle size d50 of at least 7.0 &#x3bc;m and a pore diameter of 4.0 nm to 30.0 nm.

Two-component mortar mass and use thereof

The invention relates to two-component chemical fastening systems, the A-component containing an unsaturated polyester and a reactive diluent, and the B-component containing a peroxide and an extender, wherein the extender is either a monomeric component according to formula 1(A&#x2014;CH&#x2550;CH&#x2014;O)&#x2014;R &#x2003;&#x2003;(formula 1)or a resinous compound comprising, in a covalently built-in manner, a component having vinyl ether group(s), and the content of the peroxide in the B-component is from 0.5 to 99 wt. %. In the formula A, R and n are specified as hydrogen or Calkyl; C(hetero)-aliphatic with hydroxyl or amino groups, or poly(C)glycol with 2&#x2013;120 glycol units; and 1 to 4, respectively. The resinous compounds with built-in vinyl ether group(s) (0.5 to 50 wt. %, calculated as indicated) are obtained by reaction of a mixture of appropriate amounts of: The invention also relates to methods for preparing (the B-component) of such two-component chemical fastening systems, as well as to use of the systems for chemical fastening.

Two-component chemical fastening systems

The invention relates to peroxide compositions comprising a reactive diluent for the peroxide, wherein the diluent is either a component containing one or more vinyl ether group(s) and having a monomeric structure according to formula 1, (A&#x2014;CH&#x2550;CH&#x2014;O)&#x2014;R, or is a suitable resinous compound comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s). In the formula The resinous compounds comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s)are obtained by reaction of: The invention also relates to the preparation of such compositions and to the use of such reactive diluents for peroxides in radically curing of unsaturated polyester resins for structural applications.
