DESCRIPTION:
Corkdam consists of a calendered, vulcanized material prepared from granulated cork and a sponged synthetic rubber binder. It has a cotton backing keyed into the undersurface to add stability and can be supplied with or without a pressure sensitive adhesive backing.
APPLICATION:
Corkdam can be used as a highly conformable resin dam to control the edge resin flow from composite layups during cure.
