The FastPour mandrel technology allows water soluble mandrels to be formed on-site. FastPour technology uses a unique binder system that provides rapid strength development, rapid set times, and a wide range of operational temperatures (up to 750-800°F). Demold times are as fast as 15 minutes. It comes as a dry powder that is water activated. Mandrels must be dried and pre-heated before use to a core temperature of >300°F (450 to 700°F recommended) to ensure water solubility.
FastPour mandrels are suitable for autoclave/non-autoclave composite processing. They have been tested to 370°C/700°F.
