Information was lacking on the comparative properties of Omicure™ BC-120 vs. the more widely used BF3-Amine Complexes. BCl3 and BF3 are in a class of curing agents known as Lewis Acids. Both are gaseous under standard temperature and pressure conditions. Complexes are made to provide liquid or solid forms under conditions of normal use. When heated, boron tri-halide is liberated to catalyze the cure of the epoxy resin. The use of different amines will provide complexes that liberate boron trihalide at different temperatures. This study was undertaken to compare the characteristic properties of BC-120 against several different BF3 Complexes.
