Carboline, a subsidiary of RPM International, is a global manufacturer of high-performance coatings, linings, and fireproofing products headquartered in Maryland Heights, Missouri. Founded in 1947, Carboline's products have been used in some of the world's harshest environments and industrial sectors, including oil and gas, water and wastewater, marine, rail, and more.
Carboline founder Stanley Lopata graduated from Washington University in St. Louis in 1935 with a degree in chemistry.[1] While selling corrosion-resistant equipment to the chemical industry as a manufacturer's representative, Lopata noticed damage in one of his customers' glass-lined tanks. In response, Lopata developed his own carbon-based liquid repair product for the tanks.[2] Out of this carbon-based lining came "Carboline."
Carboline was acquired by RPM International Inc. in 1985.[3] It operates within RPM's Performance Coatings Group.
