| 摘要 |
Hot-curing reactive compositions are described that are based on natural and/or synthetic olefinic elastomers, containing double bonds, and vulcanizing agents, and which comprise at least one liquid polyene having a molecular weight of between 400 and 80 000, preferably between 800 and 25 000, at least one block copolymer having at least one polyene block and at least one saturated block, a vulcanizing system composed of sulphur and accelerants and/or, if desired, quinone oximes. These compositions are suitable for use as a one-component adhesive, sealant or coating material in automotive bodyshop assembly, with high tensile shear strengths and high impact peel strength, particularly at low temperatures. ® KIPO & WIPO 2009
