Vertrel® C-HD is widely used for the following applications:
Compatibility and Soils
Vertrel® C-HD is compatible with most plastics and elastomers and can be used to clean a wide variety of soils. To check materials compatibility and determine if Vertrel® C-HD is the optimum solution for your application, please contact us.
Vertrel® C-HD has zero ozone-depletion potential. It is used extensively to replace CFC-113, methyl chloroform, hydrochlorofluorocarbons (HCFCs), and perfluorocarbons (PFCs) in several applications.
Vertrel® C-HD has been 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® C-HD 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.
The components of Vertrel® C-HD 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 applications indicated in the Vertrel® C-HD Safety Data Sheet regulatory section.
Flammability and Toxicity
Vertrel® C-HD exhibits no open- or closed-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 but has the potential to ignite in an open vessel or in case of a spill, if an ignition source is present. However, laboratory tests with virgin solvent in an open vessel show the solvent will not sustain combustion, and quickly self-extinguishes. Users should clear equipment of all vapors and liquids before performing any maintenance operations that could result in an ignition source.
Flash point data and limits of flammability in air provide the user with additional information that could 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.
Acute toxicity studies show that Vertrel® C-HD has low toxicity. It could pose slight skin and eye irritation and has low inhalation toxicity. For details of exposure limits please refer to the Vertrel® C-HD brochure.
