A cold curable composition comprises (1) a polyepoxide having an epoxy equivalency greater than 1.0, (2) an alkyl substituted monohydric phenol and (3) a bituminous material composed mainly of hydrocarbons, said composition being capable of cure with an aliphatic or cycloaliphatic amine. Specified polyepoxides are the epoxidised esters of polyethylenically unsaturated monocarboxylic acids, the epoxidised esters of unsaturated monohydric alcohols and polycarboxylic acids, the epoxidised esters of unsaturated alcohols and unsaturated carboxylic acids, epoxidised derivatives of polyethylenically unsaturated polycarboxylic acids, epoxidised polyesters of ethylenically unsaturated polyhydric alcohols and/or ethylenically unsaturated polycarboxylic acids, epoxidised polyethylenically unsaturated hydrocarbons, epoxidised polymers and copolymers of diolefins and polyglycidyl ethers of polyhydric phenols and alcohols. Specified alkyl phenols are dinonyl, dioctyl, didoceyl, ditetradecyl, dioctadecyl, trinonyl, nonyl, octyl, heptyl, pentadecyl, diheptyl, heptyl dodecyl, heptyl ditetradecyl, eicosanyl and tritetradecyl phenols and nonyl cresols. Specified bituminous materials are asphalts, high boiling extracts of petroleum, residual fuel oils, coal tar, refined coal tar and coal tar pitches. Solvents e.g. xylene and benzene, liquid poly-and mono-epoxides e.g. liquid glycidyl polyethers of polyhydric alcohols, butyl glycidyl ether and phenyl glycidyl ether and fillers e.g. sand, crushed rock, finely divided shells, crushed quartz, aluminium oxide and resin particles may be present in the compositions. Specified amino-hardening agents are triethylamine, ethylene diamine, diethylamine, diethylene triamine, triethylene tetramine, 1:4-diaminocyclohexane N:N1-diethyl-1:3-propane diamine, dicyandiamide, melamine and fatty acid salts of amines. In the examples a polyglycidyl ether of bis-phenol-A is mixed with diethylene triamine and (I) to (III) dinonyl phenol and straight run asphalt; (IV) and (V) dinonyl phenols and fuel oil; (VI) dinonyl phenols and Bunker C fuel oil; (VII) and (VIII) petroleum extract and dinonyl phenols; (IX) and (X) didoceyl phenols and straight run asphalt; (XI) and (XII) nonyl phenols and straight run asphalt; (XV) dioctyl phenol and straight run asphalt; (XVII) the diglycidyl ester of dimerised linoleic acid, dinonyl phenols and asphalt; and (XX) asbestos, silica, industrial fuel oil, dinonyl phenols, xylene and secondary butanol. In the remaining examples: (XIII), examples (I), (IV), (IX) and (XI) are repeated using as the epoxide equal quantities of the diglycidyl ester of dimerised linoleic acid and the triglycidyl esters of trimerised linoleic acid; (XIV), Examples (I), (IV), (IX) and (XI) are repeated using a different diglycidyl ether of bis-phenol-A; (XVI) an adduct of dimerised linoleic acid with a diglycidyl ether of bis-phenol-A is mixed with dinonyl phenol, industrial fuel oil and diethylene triamine; (XVIII), Examples (I), (IV), (IX), (XI) and (XVI) are repeated, replacing the bituminous material by each of the following: coal tar pitch, refined coal tar, and middle oil and (XIX), (I), (IV), (IX), (XI), (XVI) and (XVIII) are repeated with each of the following curing agents in turn:-1:4-diaminocyclohexame and N-amino ethyl piperazine. U.S.A. Specification 2,633,458 is referred to.ALSO:The examples describe the coating of cement concrete surface by spreading with cold curable compositions comprising a polyglycidyl ether of bis-phenol-A, (pre-reacted with dimerized linoleic acid in (XVI), diethylene triamine and (I) to (III) dinonyl phenol and straight run asphalt; (IX) and (X) didoceyl phenols and straight run asphalt; (XI) and (XII) nonyl phenols and straight run asphalt; (XV) dioctyl phenol and straight run asphalt; and (XVI) dinonyl phenols and industrial fuel oil. In Example (XX), metal panels are sprayed with a cold curing composition comprising asbestos, silica, a polyglycidyl ether of bis-phenol-A, industrial fuel oil, dinonyl phenols, xylene, secondary butanol and diethylene triamine.
