  • Mold release agent for urethane foamed rubber
    Patent number: 4028120
    Abstract: A mold release agent for foamed rubber formulated from the sodium soap of tall oil acids, kerosene and paraffin wax has improved mold release properties. This mold release agent is effectively removed from the molded articles by water washing, thus eliminating the need of hydrocarbon solvents. A preferred method of manufacture of the mold release agent is also described combining the tall oil and a paraffin base oil and heating to 125.degree. F., neutralizing with aqueous alkaline solution dehydrating and heating to 315.degree. F., adding 25% more paraffin base, cooling while stirring, adding wax at 245.degree.
