    Abstract: Poly-1, 2-epoxides are cured with tetrahydrocyclopentadienylenediamine of the formula or a substitution product thereof bearing C1- 4 alkyl groups. Up to 50% by weight of the tetrahydrocyclopentadienylenediamine may be replaced by a conventional curing agent in compositions containing 1 to 3 equivalents of the diamine and 1 equivalent of the polyepoxide. The curable compositions may also contain levelling agents and organic solvents and are useful as moulding, coating, encapsulating, laminating and bonding compositions.ALSO:Coatings on, for example, sheet glass and sheet metal are produced by applying lacquers comprising a polyepoxide and a tetrahydrotricyclopentadienylenediamine of the formula:- or a C1-4 alkyl substituted tetrahydrotricyclopentadienylenediamine with as optional ingredients conventional curing agents for epoxy resins organic solvents and levelling agents.
