All Purpose Foam is a rich, high-density foam that will cling to vertical surfaces allowing enough time to close and mold over the top along with blowing out the vents. This is made especially for delrin gas build-up. Why was ALL PURPOSE FOAM developed? All Purpose Foam was formulated to eliminate costly problems from rust formation on the backs of molds, paint softening on expensive equipment, and costly down time caused by gas build-up in vents.
