Introduction

Plastic and Elastomer Compatibility

Vertrel™ XM is a proprietary azeotrope of Vertrel™ XF

Most plastics and elastomers can be safely cleaned inhydrofluorocarbon (2,3-dihydrodecafluoropentane) with

Vertrel™ XM. Tables 3 and 4 summarize test results onmethanol. It is ideally suited for use in vapor degreasing

Significant New Alternatives Policy (SNAP) program, as a
substitute for ozone-depleting substances.
Its unique properties (Tables 1 and 2) include a high density,
low viscosity, and low surface tension for effective particle
and soil removal.

Cleaning ProcessVapor 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 asecondary set of low temperature (–29 °C [–20 °F])
condenser coils to greatly reduce vapor losses.

Due to the azeotropic nature of Vertrel™ XM, the productis easily recoverable by off-line or in-line distillationequipment, such as a vapor degreaser or still. The presenceof soil, however, may alter the characteristics of thematerial during the recovery operation. Recovery should
be closely monitored to ensure operating levels aremaintained. Users should test the spent Vertrel™ XM toensure proper classification for waste disposal.

Storage/Handling
Vertrel™ XM is thermally stable and does not oxidize or
degrade during storage. Store in a clean, dry area. Protectfrom freezing temperatures. If solvent is stored below –10 °C(14 °F), mix prior to use. Do not allow stored product toexceed 52 °C (125 °F) to prevent leakage or potential
rupture of container from pressure and expansion.
Consideration should be given to retrofit of existing, orpurchase of new, vapor degreasing equipment to provide
vapor containment technology that enables safe andeconomical use of Vertrel™ XM.

The methanol component of Vertrel™ XM is considered ahazardous air pollutant (HAP) and, therefore, is subject toNESHAP regulation. Spent Vertrel™ XM is not a RCRA
characteristic or listed waste. However, addition ofcontaminants could change that status. Methanol isincluded in the SARA Title III Section 313 list of toxic
chemicals and is subject to SARA Title III (EPCRA)
