Abstract
Abstract Diesters and triesters of dibasic acids, glycols, triols, and glycidyl esters, when formulated with polyfunctional isocyanates, form coating compositions which require little or no organic liquid carrier. These compositions air-dry or cure at low temperatures, and give off little or no organic liquid on drying or curing, thereby conforming to most anti-pollution legislation and saving fuel.
