Cortec®EcoLine® 4320/4330 Stand Ready to Answer EPA Methylene Chloride Ban

Saturday, Apr 20, 2019

Several months before the EPA announced its final rule banning methylene chloride from consumer paint stripper sales because of acute fatalities, Cortec®addressed the problem with the release ofEcoLine® 4320 and 4330. These two biobased alternatives go above and beyond EPA requirements by not containing methylene chloride or N-methylpyrrolidone (NMP), another paint stripper chemical that has been frowned upon for potential adverse health effects1 and which several retailers have already voluntarily chosen to discontinue.

EcoLine® 4320 and 4330 answer both concerns and are formulated with renewable materials and recycled solvent. EcoLine® 4320 and 4330 contain 50% USDA certified biobased content and are qualified products under the mandatory federal purchasing initiative of the USDA BioPreferred® Program (for more information, go to

EcoLine® 4320 and 4330 have low odor and are VOC compliant to the California Regulation for Reducing Emission from Consumer Products.* They do not contain any California Prop 65 components that cause cancer, birth defects, or other reproductive harm. They also do not contain chlorinated solvents, toluene, or acetone.

EcoLine® 4320 and 4330 paint strippers are designed to remove coatings, inks, and resins from metal, concrete, and wood surfaces. They are effective on a wide variety of paints and contain flash corrosion inhibitors to prevent rust and tarnishing throughout the stripping process. EcoLine® 4320 should be used in dip tanks and on horizontal surfaces. EcoLine® 4330 is a gelled version for use on vertical, overhead, or complex surfaces.

While the new EPA rule (which goes into effect in about six months) only addresses consumer product sales, Cortec® takes the precaution to a level higher by providing methylene-chloride-free strippers to the industrial market, as well, for the benefit of users in the workplace.
