Patent ID: 8791172

Claim:
A kit comprising: a kit component (a), which contains as components 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, wherein kit component (a) contains 15-85 weight percent of the methacrylic acid ester (a1) and less than 85 weight percent of the filler (a2), based on a total weight of the components contained in kit component (a), a kit component (b), which contains as components 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, wherein kit component (b) contains 15-85 weight percent of the methacrylic acid ester (b1) and less than 85 weight percent of the filler (b2), based on a total weight of the components contained in kit component (b), a kit component (c), which contains as components 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), wherein kit component (c) contains 15-85 weight percent of the methacrylic acid ester (c1) and less than 85 weight percent of the filler (c2), based on a total weight of the components contained in kit component (c), wherein each of the kit components (a), (b) and (c) is a paste, wherein at least one of the kit components (a), (b) or (c) contains at least one halide salt, wherein at least one of the kit components (a), (b) or (c) contains at least one cross-linking agent, and wherein, based on a total weight of the components contained in the kit components (a), (b) and (c), (i) a total weight percentage of the methacrylic acid esters (a1), (b1) and (c1) lies in a range of 15-50 weight percent, (ii) a total weight percentage of fillers (a2), (b2) and (c2) lies in a range of 40-85 weight percent, (iii) a weight percentage of the radical initiator (a3) lies in a range of 0.01-4 weight percent, (iv) a weight percentage of the radical initiator (b3) lies in a range of 0.01-4 weight percent, (v) a weight percentage of the accelerator (c3) lies in a range of 0.000001-3 weight percent, (vi) a total weight percentage of the at least one halide salt lies in a range of 0.001-5 weight percent, and (vii) a total weight percentage of the at least one cross-linking agent lies in a range of 0.2-3 weight percent.
