September, 1926 A Perfect Anti-Corrosive Protective Coating a [ TRACE MARK \ Thorkote is a plastic material easily applied over insulating materials by brush, trowel or spraying. It fills a long felt need for a waterproof covering for Magnesia and other heat insulation. Thorkote is pure asphalt, emulsified in water, and is applied cold. The coating left after evap- oration of the water is waterproof, rust- proof, and fire-resistant, unaffected by brine drip, acid fumes and corrosive gases. It is free from weather cracks, adheres permanently to any solid surface, wet or dry, and is flexible and ductile at low tem- peratures, yet will not creep or flow at comparatively high temperatures. It is the ideal protective agent for use in the marine field on anything requiring perma- nent covering. Some Marine Some Marine Users: Uses: S.S. Leviathan Feed and Oil Heaters S.S.
