Abstract :
Several Organotin-amine molecular complexes have been synthesized and evaluated as latent catalysts and accelerators for curing epoxy and epoxy-anhydride resins. With epoxy-anhydride resin formulations, the addition of ~0.10% of some of these organotin-amine complexes gives fast gel times at 150-175°C combined with reasonably good storage stability at room temperature and low power factors in cured resin samples (measured at 150°C)
