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 asubstitute for ozone-depleting substances.
Physical properties of Vertrel™ MCA are shown in Tables 1aand 2.

Cleaning Processstress, may show slight cracking or crazing damage andVapor degreasing should be used for optimum cleaning
effectiveness and economy. Modern vapor containmenttechnology is recommended for both batch and in-line
equipment. These systems have higher freeboard and asecondary set of low-temperature (–29°C [–20°F])
condenser coils to reduce vapor loss.

materials is available from Chemours upon request.
Elastomer swelling and shrinking will, in most cases, revert
shrinkage, and extractables are strongly affected by thecompounding agents, plasticizers, and curing used in themanufacture of plastics and elastomers. Therefore, priorin-use testing is particularly important.

Oxygen Cleaning
Oxygen cleaning requires solvents that have good degreasing
properties and a high cleaning effectiveness factor (i.e., Kbvalue >20). These solvents must also be easy to remove fromcleaned parts (i.e., boiling point >25°C [77°F] and <65°C[149°F]), non-corrosive, compatible with commonly used
metallic and non-metallic materials, compatible with oxygen(i.e., low particle count), have low NVR, and nonflammable (i.e.,no flash point and no flammability limits). Vertrel™ MCA
meets these oxygen cleaning requirements as shown in
Table 4. Vertrel™ MCA is listed by the Compressed Gas
Association in the directory of cleaning agents for oxygen
service and also meets liquid oxygen mechanical impact
testing in accordance with ASTM method.

Service or any Chemours authorized distributor. When
handled in accordance with Chemours recommendations
and exposure is minimized, no adverse health effects areexpected from exposure to Vertrel™ MCA. Vertrel™ MCA
should only be used with adequate ventilation, and NIOSHapproved respiratory protection should be employed when
inhalation exposure is possible at high concentrations. At
room temperature, Vertrel™ MCA may cause skin irritation,eye irritation, drowsiness, and/or dizziness.

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 theuser 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 ensurecompliance with NFPA standards and local fire codes.

Drum pumps are recommended to dispense Vertrel™ MCA
from its container. Refer to the SDS for specific handlingprecautions and instructions.

Environmental Legislation
Vertrel™ MCA has negligible ozone depletion potential andlow global warming potential (Table 7).
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 theSignificant New Use Rule (SNUR) and should be used only inthe 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)

Recoveryreporting requirements.

Due to the azeotropic nature of Vertrel™ MCA, the product isTable 7. Environmental Properties

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 properclassification for waste disposal.
