  • Composition and method using same to remove urethane products from a substrate
    Patent number: 8003588
    Abstract: A composition for removing urethane products from a wide variety of substrates without the need for scraping, scrubbing, sanding, sandblasting and the like is provided. The composition is formed by combining water, a polar organic solvent, a mixture of organic esters, a hydrocarbon, and a polyether. The composition may optionally be formed by combining the components recited above along with an anionic surfactant. The composition may optionally be formed by combining the components recited above along with a thickener.
