Popis:	BF2-chelates are powerful polymerisation catalysts for epoxy resins; derivatives of β-diketones and of β-ketoamides are especially interesting as ‘latent’ hardeners. Comparison of these metal halide chelates with BF3-amine complexes in various epoxy systems has shown the chelates to be superior in several respects. Particular advantages are the ease with which reactivity can be varied by choice of chelate structure and by addition of moderators, and the reduced sensitivity to atmospheric moisture during cure. Use of BF2-Chelates also gives cured products with better electrical properties, and in many cases better mechanical properties, than with BF3-amine complexes.
