    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.

    Abstract: A process for the production of basic polyamides compatible with substances capable of being cured to plastics comprises reacting at a temperature of between 100 DEG and 350 DEG C., an o : o 1-octane and/or -nonane dicarboxylic acid which contains as a substituent an aliphatic hydrocarbon radical having at least 8 carbon atoms in a continuous chain with a mixture of (a) an aliphatic polyamine, and (b) an aromatic and/or araliphatic polyamine, said polyamines having at least two primary amino groups in a molar ratio of carboxylic acid to amine of 1 : 1.1 to 1:3. Mono- and other di-carboxylic acids, e.g. acetic, benzoic, stearic, adipic, glutaric, sebacic, a -methyl-glutaric, sebacic, isophthalic and terephthalic acid may be present in the reaction mixture. Specified polyamines are ethylene, trimethylene, tetramethylene, pentamethylene, hexamethylene, decamethylene xylylene and o-, m- and p-phenylene diamine, 1 - amino - 9 - aminomethyloctadecane, 1-amino - 10 - aminomethyloctadecane, diaminocyclohexane, di-(aminomethyl) benzenes, 4 : 41-diamino - di - n - butyl ether, a - aminopyridine, polyamines of the formula H2N-(CH2)m-[NH-(CH2) m]n-NH2 where m is an integer from 2 to 6 and n is an integer from 1 to 4, diethylene triamine, triethylene tetramine, dipropylene triamine and tripropylene tetramine. Monoamines, e.g. ethylamine, stearylamine or aniline may also be present in the reaction mixtures. The products of the invention may be used for curing polyepoxides or precondensed phenol, urea or melamine-aldehyde resins.

    IPC: C08G59/50

    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.
