| titleOfInvention | Epoxy resin compositions having improved low temperature cure properties and processes and intermediates for making the same |
| abstract | Two-component epoxy resin compositions are disclosed. The polyepoxide component comprises one or more oligomers having at least one aromatic ring substituent R4X1—in which R4 represents a substituted or unsubstituted aliphatic group having at least 4 carbon atoms, a substituted or unsubstituted cycloaliphatic group having at least 5 carbon atoms, a poly(oxyalkylene) group wherein the average number of carbon atoms per oxyalkylene unit is at least 3, or a aryl group having one or more of the foregoing substituents, bonded directly to the aryl group via a covalent bond or bonded to the aryl group via an oxy, a thio, or a carbonyloxy divalent linking group, or a combination thereof, and X1 represents a covalent bond or a divalent moiety selected from oxy, thio, carbonyloxy, and —X2C(R2)2C(R1)(OH)C(R2)2O—, in which X2 represents a covalent bond or a divalent moiety selected from oxy, thio, and carbonyloxy, R1 represents —H or —C1-14 alkyl, and each R independently represents —H or —CH3. The curing agent component comprises one or more compounds of Formula (VI): in which each Z independently represents a divalent hydrocarbylene group having from 2 to 20 carbon atoms; R5 represents a Cg-2O saturated or unsaturated aliphatic ring substituent; each R6 independently represents a hydrogen atom or a hydrocarbyl group having from 1 to 10 carbon atoms and optionally at least one hetero atom; each m independently is an integer in the range from 1 to 4; k represents an integer in the range from 1 to 3; and j represents 1 or 2, and/or one or more adducts of one or more Formula (VI) compounds. The two-component epoxy resin compositions are capable of faster cure at low ambient temperatures, such as at temperatures below 1O0C, such as below 50C or even below O0C, to quickly form nonsticky coatings and seals having a good appearance. n (R 5 )Ph(OH) j [CHR 6 NH(ZNH) m H] k (VI) |
