and/or
c) at least one at least oligomeric addition product
of at least one silane having at least one hydrolyzable group and at least one (meth)acrylate group
or at least one silane having at least one hydrolyzable silane group and at least one cyclic dicarboxylic anhydride group
onto at least one compound having at least two terminal amino groups

and/or
d) at least one at least oligomeric addition product
of at least one isocyanatosilane and/or epoxysilane having at least one hydrolyzable silane group
onto at least one compound having at least two terminal amino groups optionally in combination with at least one further monoisocyanate and/or an epoxide compound,
in an amount of less than 5% by weight, based on the total weight of the polymer mixture, as coupling additive,

II) as binder
a curable system which comprises at least one polymer having at least two epoxide end groups and can be at least partially cured by interaction of the epoxide groups of this polymer with the amino groups of at least one of the components I) a)-d) and at least one further hardener component and optionally an accelerator,

III) at least 20% by weight, based on the total weight of the polymer mixture, of inorganic, optionally multiparticulate fillers as aggregates and
IV) optionally customary auxiliaries.

2. The curable polymer mixture as claimed in claim 1 , wherein it contains less than 1% by weight based on the total weight of the polymer mixture, of the coupling additive component I).

3. The curable polymer mixture as claimed in claim 1 , wherein the binder component II) is present in an amount of less than 80% by weight, based on the total weight of the polymer mixture.

4. The curable polymer mixture as claimed in claim 1 , wherein fillers selected from the group consisting of silicon-containing compounds, aluminosilicates, aluminum silicates and inorganic oxygen compounds of aluminum and magnesium are present as inorganic fillers.

5. The curable polymer mixture as claimed in claim 4 , wherein oxidic silicon compounds in the form of continuous fibers, are used as inorganic, silicon-containing compounds.

6. The curable polymer mixture as claimed in claim 4 wherein the inorganic filler component III) is pretreated with at least part of the coupling additive component I).
