Abstract
Amine adducts comprising a reactive amine curing agent containing an aromatic silane epoxy along with improved coatings made by combining the amine adduct with additional epoxy material. The amine adducts, when formulated and cured with an epoxy material, cures in several hours and gives a protective coating material that cures without blush or CO.sub.2 incorporation. Specific embodiments of the amine adduct contain a bisepoxy compound, such as 2,11-bis(3-glycidylphenyl)-2,11dimethyl-2,11-disiladodocane (n=4), for example, while the amine functionalized compound may be ethylenediamine (90.degree. C., 120.2 g, 20 mol) or aminoethylpiperazine, respectively. A number of chemical compounds are also disclosed.
