A compound of the formula (I) ##STR1## wherein R is hydrogen, methyl of C.sub.2 -C.sub.5 alkyl and R.sup.1 is O-phenylene, a saturated or unsaturated 1,2-cyclohexylene group; a 2,3-bicyclo[2.2.2]-hept-5-enyl group of the formula (II) ##STR2## or a saturated or unsaturated aliphatic group of about 2 to about 20 carbon atoms; said O-phenylene is optionally substituted in the ring by one or two alkyl groups of from 1 to 4 carbon atoms; said 1,2-cyclohexylene and bicyclo groups are optionally substituted by one or two alkyl groups of from 1 to 4 carbon atoms and/or by one to six chlorine or bromine atoms; and said aliphatic group is optionally substituted by one or more chlorine or bromine atoms. This compound can be used as a coating compound when mixed with curing agents.

Glycidyl esters of tricarboxylic acid adducts

Coating compositions containing a polyfunctional glycidyl ether of sorbitol cured at ambient temperature with polyamidoamine hardeners exhibit unexpectedly high resistance to loss of gloss when exposed to weathering conditions. The cured product also have good mechanical and chemical properties.

Method of coating with polyglycidyl ether of sorbitol and polyamidoamine

Co-advanced epoxy resins prepared by the reaction of polyethers of polyhydric phenols, diglycidyl ethers of di-secondary alcohols and dihydric phenols, said co-advanced resins being heat curable with suitable curing agents to afford cured coating compositions exhibiting a variety of excellent physical properties and performance characteristics. The diglycidyl ethers have the following formula: ##STR1## as defined in the specification.

Co-advanced resins from copolymers of polyethers of polyhydric phenols

The adducts of monoepoxides with selected diamines, preferably m-xylylenediamine, are useful as curing agents for the curing of epoxy resin compositions at very low temperatures (25.degree.-50.degree. F., -4.degree. to 10.degree. C.).
