    Abstract: A 1-aminomethyl-2-aminopropylcyclohexane is used to cure a polyepoxide having more than one 1,2-epoxy group at 20 DEG to 200 DEG C. The polyepoxide may be a glycidyl ether of a polyhydric phenol or polyhydric alcohol. The hardening agent may have one or more substituents, e.g. cycloaliphatic, aliphatic-aromatic or aromatic hydrocarbon radicals; it may be used at 5-50 parts by weight per 100 parts of polyepoxide A filler, pigment dye or plasticizer may be incorporated into the mixture prior to curing. Urea formaldehyde or phenol formaldehyde resins may also be present.

    Abstract: Polyepoxides are cured by basic polyamides obtained by reacting a molar excess of a primary and/or secondary polyamine with an adduct of a natural resin acid with an a ,b -ethylenically unsaturated carboxylic acid and/or a derivative thereof which will form amide groups. Preferred adducts are of maleic, fumaric, itaconic, acrylic, aconitic or citraconic acid with colophony or with pimaric or abietic acids and their derivatives, whilst the preferred amines are polyalkylenepolyamines. Many polyepoxides are specified. Conventional hardeners or accelerators for the curing of polyepoxides may also be present in the curable mixtures as may be solvents. The curable compositions are useful as lacquers, moulding compositions, casting or laminating resins, dip resins, adhesives and encapsulating compositions. Polyamides are prepared by reacting a colophony acrylic acid adduct with diethylenetriamine or diethylenetriamine and 1,3-bisaminomethylbenzene under nitrogen.ALSO:Sheet steel and glass sheets are painted with lacquers comprising a polyepoxide, a polyamide derived from a molar excess of a polyamine and an adduct of an a , b -ethylenically p unsaturated carboxylic acid with a natural resin acid and an organic solvent (see Division C3).

    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.
