Abstract: An ebonite tape for coating metal substrates is made either of a single component mixture or a two-component mixture. A single component mixture includes unsaturated polymers, a sulfur vulcanization agent, a sulfur solubilizer, a vulcanization accelerator, and a vulcanization activator. Preferably, the sulfur solubilizer is polyamine, and the vulcanization accelerator is tetramethylthiuram disulfide. Reaction of polyamine and tetramethylthiuram disulfide causes a gelation in the mixture at ambient condition. A two-component mixture includes first and second components. First component includes first unsaturated polymers having first functional groups capable of reaction at ambient temperature, a sulfur vulcanization agent, and a vulcanization activator. Second component includes second unsaturated polymers having second functional groups that will react with first functional groups of the first unsaturated polymers at ambient condition, which causes a gelation in the mixture.
