POLYSULPHIDE VULCANIZATION COMPOSITION

摘要

The composition is used for application in the form of different protective coatings, as insulator in road or housing construction, etc. The degree and speed of its vulcanization do not depend on the environment. It has high technical and ecological characteristics. It avoids the typical and unpleasant smell of the mercaptan polysulphides and the toxicity of the vulcanization agents, additives and filters. The composition includes polysulphide polymer and/or co-polymer containing from 1 mol/kg SH groups having molecular mass from 2000 to 200,000, degree of polysulphidity from 2.2 to 4.0, degree of bifurcation to 4% molar and polymerization degree from 20 to 500, in quantities from 90 to 110 wt. parts, having the general formula /formula/ having the respective meanings of the substitutes. In addition, the composition contains in wt.pts: up to 75 modifier, 0.2 to 20 vulcanization agent, up to 25 polar solvent or reagent, from 5 to 50 acceptor, up to 150 fillers and other additives.
