| The TC-312 A/B polyurethane foam system is a rigid, closed cell foam with a density of 12 lbs. per cubic foot. The TC-312 can be easily mixed by hand in small batches using a rapid, vigorous mixing action or by using a Jiffy Mixer® in a drill to provide a high-shear mix in small to large quantities. For low to high production, this foam system can also be machine dispensed using BJB's Centerpointe Meter-Mix equipment. Cured parts can be sanded, stapled, painted or stained within a short time after demolding. |
