Vertrel™ MCA is a proprietary azeotrope of Vertrel™ XF hydrofluorocarbon (1,1,1,2,2,3,4,5,5,5-decafluoropentane) with trans-1,2-dichloroethylene. It is ideally suited for use in vapor degreasing equipment. Its enhanced solvency power, compared to Vertrel™ XF alone, makes it particularly effective for precision and specialty cleaning with difficult soils. Vertrel™ MCA has negligible ozone depletion potential and low global warming potential. It can replace CFC-113, AK-225, methyl-chloroform (1,1,1-TCA), hydrochlorofluorocarbons (HCFCs), and perfluorocarbons (PFCs) in many applications. Vertrel™ MCA is accepted by the U.S. Environmental Protection Agency (EPA) under the Significant New Alternatives Policy (SNAP) program, as a substitute for ozone-depleting substances.

Vertrel™ MCA is compatible with most polymeric materials commonly encountered in degreasing of precision parts. Acrylic, ABS, and polycarbonate parts, particularly if under stress, may show slight cracking or crazing damage and should be tested. EPDM, butyl rubber, Buna-S, and neoprene are recommended for elastomeric parts.

Vertrel™ MCA was found compatible with aluminum, copper, and iron, with and without oil present, after exposure for 2 weeks at 120°C (248°F) in sealed tubes. Contact with highly basic process materials, pH 10 or above, is not recommended.
