Vertrel™ MCA
  • Vertrel™ MCA

  • Description :

    Vertrel™ MCA has zero ozone depletion potential and low global warming potential. It can replace CFC-113, methylchloroform (1,1,1-TCA), hydrochlorofluorocarbons (HCFCs), and perfluorocarbons (PFCs) in many applications.

Vertrel™ MCA is a proprietary azeotrope of Vertrel™ XF hydrofluorocarbon (2,3-dihydrodeca-fluoropentane) 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 zero ozone depletion potential and low global warming potential. It can replace CFC-113, methylchloroform (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.

Cleaning Process

Vapor degreasing should be used for optimum cleaning effectiveness and economy. Modern vapor containment technology is recommended for both batch and in-line equipment. These systems have higher freeboard and a secondary set of low-temperature (–29°C [–20°F]) condenser coils to reduce vapor loss.

Vertrel™ MCA has a broad range of cleaning capabilities. Table 1 lists some typical soils readily removed from parts in a short vapor degreasing cycle.

Plastic and Elastomer Compatibility

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.

Tables 2 and 3 summarize test results on short-term exposures of unstressed plastics and elastomers simulating a typical cleaning cycle. Long-term compatibility data simulating exposure of vapor degreaser construction materials is available from Miller-Stephenson upon request.

*Material composition varies depending upon compounding agents, plasticizers, processing, etc. Specific materials should be tested for compatibility with solvent.

*Swelling, but with low extractables

Elastomer swelling and shrinking will, in most cases, revert to within a few percent of original size after air drying. Swell, shrinkage, and extractables are strongly affected by the compounding agents, plasticizers, and curing used in the manufacture of plastics and elastomers. Therefore, prior in-use testing is particularly important.

Metals and Other Compatibility

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.

Safety/Flammability

Vertrel™ MCA exhibits no closed cup or open cup flash point and is not classified as a flammable liquid by NFPA or DOT. In addition, the product has no vapor flammability limits in air. Flash point data and limits of flammability in air provide the user with additional information that should be used as elements of a fire risk assessment and to determine guidelines for the safe handling of volatile chemicals. Users should ensure compliance with NFPA standards and local fire codes.

Recovery

Due to the azeotropic nature of Vertrel™ MCA, the product is easily recoverable by off-line or in-line distillation equipment, such as a vapor degreaser or still. The presence of soil, however, may alter the characteristics of the material during the recovery operation. Recovery should be closely monitored to ensure operating levels are maintained. Users should test the spent Vertrel™ MCA to ensure proper classification for waste disposal.

Environmental Legislation

Vertrel™ specialty fluids have zero ozone depletion potential and low global warming potential (Table 7). They are used as alternatives to CFC-113, methylchloroform, HCFCs, and PFCs in many critical cleaning, drying, carrier fluid, and other high-value specialty uses where reliability is paramount.

Vertrel™ MCA is accepted by the EPA under the SNAP program as a substitute for ozone-depleting substances.

The components of Vertrel™ MCA are listed in the TSCA inventory. One component, HFC-43-10mee, is subject to the Significant New Use Rule (SNUR) and should be used only in the indicated applications. See SDS Regulatory Section.

Vertrel™ MCA is not a hazardous air pollutant (HAP) and, therefore, not subject to NESHAP regulation. Vertrel MCA is not included in the SARA Title III Section 313 list of toxic chemicals and is not subject to SARA Title III (EPCRA) reporting requirements.
