Kit comprises: a component (a), which contains at least (a1) a mono-functional, hydrophobic methacrylic acid ester, (a2) a filler, and (a3) a radical initiator soluble in the methacrylic acid ester (a1) and having at least one peroxide group, a component (b), which contains at least (b1) a mono-functional, hydrophobic methacrylic acid ester, (b2) a filler, and (b3) a radical initiator soluble in the methacrylic acid ester (b1) and having no peroxide group, and a component (c), which contains e.g. at least (c1) a mono-functional, hydrophobic methacrylic acid ester. Kit comprises: a component (a), which contains at least (a1) a mono-functional, hydrophobic methacrylic acid ester, (a2) a filler, and (a3) a radical initiator soluble in the methacrylic acid ester (a1) and having at least one peroxide group, where the component (a) contains 15-85 wt.% of methacrylic acid ester (a1) and less than 85 wt.% of filler (a2), a component (b), which contains at least (b1) a mono-functional, hydrophobic methacrylic acid ester, (b2) a filler, and (b3) a radical initiator soluble in the methacrylic acid ester (b1) and having no peroxide group, where the component (b) contains 15-85 wt.% of methacrylic acid ester (b1) and less than 85 wt.% of the filler (b2), and a component (c), which contains at least (c1) a mono-functional, hydrophobic methacrylic acid ester, (c2) a filler, and (c3) an accelerator soluble in the methacrylic acid ester (c1) and capable of forming radicals from the radical initiators (a3) and (b3), where the component (c) contains 15-85 wt.% of methacrylic acid ester (c1) and less than 85 wt.% of filler (c2), where at least one of the components (a), (b) or (c) contains at least one halide salt and at least one crosslinking agent, and where, based on a total weight of the components contained in the components (a), (b) and (c), (i) a total weight percentage of the methacrylic acid esters (a1), (b1) and (c1) lies at 15-50 wt.%, (ii) a total weight percentage of fillers (a2), (b2) and (c2) lies at 40-85 wt.%, (iii) a weight percentage of the radical initiator (a3) lies at 0.01-4 wt.%, (iv) a weight percentage of the radical initiator (b3) lies at 0.01-4 wt.%, (v) a weight percentage of the accelerator (c3) lies at 0.000001-3 wt.%, (vi) a total weight percentage of the halide salt lies at 0.001-5 wt.%, and (vii) a total weight percentage of the crosslinking agent lies at 0.2-3 wt.%. An independent claim is included for a paste comprising 15-50 wt.% of at least one mono-functional, hydrophobic methacrylic acid ester, 40-85 wt.% of at least one filler, 0.01-4 wt.% of at least one radical initiator soluble in the methacrylic acid ester and having at least one peroxide group, 0.01-4 wt.% of at least one radical initiator soluble in the methacrylic acid ester and having no peroxide groups, 0.000001-3 wt.% of at least one accelerator soluble in the methacrylic acid ester and capable of forming radicals from the radical initiators, 0.001-5 wt.% of at least one halide salt, and 0.2-3 wt.% of at least one crosslinking agent. |
