A release agent for separation of a pattern from a mold cavity or core or the like. The agent consists essentially of an organosiloxane polymer fluid, comminuted aluminum, and a fluorocarbon solvent. Illustratively, the agent may include 0.6% by weight of the organosiloxane polymer fluid. The illustrative organosiloxane polymer has a viscosity of approximately 12,500 centistokes. The illustrative agent includes 3.6% by weight of an aluminum paste including approximately 65-75%, by weight, of finely divided pigment-grade aluminum and 25-35% of mineral spirits vehicle. The fluorocarbon preferably is a non-propellant grade fluorocarbon such as trichlorotrifluoroethane.
