Rust-proof sealing composition |
摘要 |
A rust-proof sealing composition contains 30 to 90 parts by weight of an epoxy resin, 8 to 30 parts by weight of a curing agent containing a carboxylic acid derivative selected from the group consisting of aminocarboxylic acid, polycarboxylic acid hydrazide having not less than 8 carbon atoms and mixtures thereof, 1 to 20 parts by weight of an electrically conductive carbon and a balance of a filler such that the total amounts make up 100 parts by weight. The epoxy resin contains 100 to 30 wt. % of a modified epoxy resin selected from the group consisting of a butadiene/acrylonitrile-modified epoxy resin, an urethane-modified epoxy resin and mixtures thereof, and 0 to 70 wt. % of an epoxy other than the modified epoxy resin.
