Sealing compounds or joint sealing compounds for roads - 30 parts by weight of polysulphide polymers to 70 parts by weight and floor coverings based on bituminous substances are -. Parts of a polyester-Moriomer mixture is known. However, they are not weatherproof. From mass after curing rubber-elastic, while polyvinyl chloride and synthetic rubber were already produced at a ratio of 10:90 parts by weight, the joint profiles, which are present in expansion joints 5 end product in a hard-elastic state, were used in concrete. However, the accelerators will have unfavorable properties, as the inhomogeneous incorporation of all components, but in front of adjacent concrete edges, easily splintered off when driving on. Furthermore, addition of the peroxide catalyst in amounts of mixtures of 1 to 5%, based on the mixture of the unsaturated unsaturated polyester, styrene and 0.5 to 3% poly- io polyester with the polymerizable monomers, are known for casting compounds, thiomercaptan , · But not inflicted in the air. In addition to cumene hydroperoxide as a catalyst, cure or dry and therefore dry without tackiness. is.

5 parts by weight of cumene hydroperoxide solution (70%) are incorporated before use. The processing time of the ready-casting compound is approximately 45 minutes at 20 ⁰ C. It is longer at temperatures below 20 ° C and shortened accordingly at 5 temperatures above 20 ° C. The mass is cured in the specified temperature range after about 1 to 4 hours.

The adhesion of this mass to concrete and wood is excellent, so that two concrete slabs joined with the narrow sides, the joint being about 1 cm wide, allow a load of over 100 kg / cm ^a . The physical measurements of this mass are as follows:
