1. A system for producing a sealant composite, the sealant composite comprising a primary sealing material and a distinct curable secondary sealing material, the system including at least three separately stored components (A, B1, B2), wherein the component (A) is the primary sealing material, comprising:
a) about 30-80% by weight of at least one olefinic polymer;
b) about 2-35% by weight of at least one polymer modified with reactive groups;
c) about 5-65% by weight of at least one filler;
d) about 5-25% by weight of at least one drying agent;
e) about 0-3% by weight of at least one stabiliser;
wherein the distinct secondary sealing material is a sealing material based on polyurethane, obtainable from a polymer component (B1) and a hardener component (B2),
wherein the polymer component (B1) is selected from the group consisting of diols, polyols, polyester polyols, and polyolefins modified with available acidic hydrogen, and
wherein the polymer component (B2) is selected from the group consisting of isocyanates, mono-, di-, tri- and polyisocyanates, and mixtures thereof,
wherein the secondary sealing material contains a catalyst and/or an initiator, wherein the catalyst and/or initiator is selected to activate the reactive groups in the primary sealing material upon contact with the catalyst and/or initiator in secondary sealing material.
