摘要： Provided are 3-oxoadipate esters of certain polyols which are useful as crosslinkers in thermosetting coating compositions. Also provided are such thermosetting compositions comprised of a curable hydroxyl-functional polymer such as a polyester or acrylic and the crosslinkers of the present invention. Such compositions offer a significant improvement in curing temperature.

摘要： This invention provides the use and preparation of certain 2,2'-diacetyl-bisacetoacetates and bis(beta-ketoesters). These compounds are useful in coating formulations as crosslinkers in conjunction with polyester, acrylic and/or other hydroxylated resins to provide coatings that cure at about 100.degree. and 175.degree. C. Certain combinations of these crosslinkers and resins cure at unusually low temperatures and provide films with good combinations of flexibility, hardness and adhesion.

摘要： This invention involves a carbamate functional polymer or oligomer made by reacting a cyclic carbonate with ammonia or a primary amine, then reacting the resulting hydroxycarbamate with a polyfunctional material containing groups reactive with hydroxyl groups to form a polyfunctional carbamate. The polymer formed is mixed with an aminoplast, coated on a substrate and cured to form a crosslinked coating.
