Hazardous Solvent Issues Replacing I I I -T in Degreasing Safer Paint Stripping with NMP ARCO Chemical Products ARCO Chemical Company Contacts & Phone Numbers

Why Chlorinated Solvents are U nder Regulatory Pressure

* A non-chlorinated alternative to Methylene Chloride

x Persist in the Environment x Tend to be carcinogenic x High exposure hazard I::
