The plastic sheeting is prepared from a mixture of 1000 parts by weight of polysulphide oligomer or polymer, from 300 to 700 parts by weight of carbon black and a curing agent based on manganese(IV) oxide. It is bonded using a polysulphide material whose composition is analogous to that of the sheeting and is preferably used as leakproof sheeting in problem areas, for example as roof sheeting, in particular in multistorey car parks, as leakproof sheeting in landfill sites or for bridge sealing. |
