Abstract
Abstract A class of epoxy compounds, (i.e. polyglycidamides) are blended with polyamines and other epoxy reactive oligomers to provide crosslinkable coating systems. When the systems are cured they are tough and abrasion resistant, possess solvent, chemical and water resistance and UV stability.
