System for producing a sealing compound for insulating glass

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.
