An Isocure Core is produced using silica sand mixed with a phenolic urethane resin used as a binding material. This core sand mixture is blown into the core-box. Along with heated air, a vaporized amine gas catalyst is then purged thru the core sand. The vaporized catalyst activates the binding resin which very quickly solidifies the core.
