Benefits & Uses

EP-921® is a unique cleaning compound designed as a substitute for MEK, MEK/Toluene blends, and lacquer washes and is excellent for resin and paint application equipment clean up.

EP-921® is a lightly regulated, low VOC, low toxicity, non-HAP containing, high flash point formulation that is ideal for functioning within the modern regulatory climate.  In fact, the emission limitation inherent in its formation may qualify it as a Maximum Available Control Technology (MACT).  Its use without vapor collection will compete favorable with the use of MEK and a 99.7% efficient vapor collection system.  Users should check with local air pollution control jurisdictions for a determination.

The formulation of EP-921® is outside the RCRA hazardous waste regulations.  None of its components are listed in SARA, Title III, Sections 302 or 313.  None of its components are listed under CERCLA.

EP-921® is the only compound utilized for paint operations cleanup that enjoys a toxicity clearance from the U.S. Army Center for Health Promotion and Preventative Medicine (CHPPM), 1 December, 1998.
