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.
Claims24
A composition for removing a urethane product from a substrate comprising:
- (a) a polar organic solvent having a dielectric constant greater than about 30 in an amount in the range of from about 80 to about 90% by weight;
- (b) at least one polyether in an amount in the range of from about 2 to about 3% by weight, the polyether comprising the molecular structure
- wherein
- R1 is an alkyl group having between about 9 and about 20 carbons, R2 is selected from the group consisting of hydrogen and methyl, and R3 is selected from the group consisting of hydrogen and alkyl, and (n) is between about 2 and about 10;
- (c) organic esters in an amount in the range of from about 4 to about 5% by weight, wherein the esters are formed by heating soybean oil in the presence of methanol and a catalyst;
- and
- (d) water in an amount of about 5% by weight.
