Vertrel SMT | Defluxing and Precision Metal Cleaning
Optimized for Rosin, Oils, and Ionic Contaminates | Low Global Warming Potential & VOC | Enhanced Safety Profile
Vertrel SMT is a proprietary azeotrope of Vertrel XF hydrofluorocarbon (2,3 dihydrodeca-fluoropentane) with trans-1,2-dichloroethylene and methanol. Vertrel SMT is engineered to provide unmatched performance in Defluxing, Precision metal Cleaning and removal of Rosin, Oils, and Ionic Contaminates. It is ideally suited for use in vapor degreasing equipment with solvency power for cleaning ionic soils and flux residues from electronic assemblies. Vertrel SMT has “zero” ozone-depletion potential, low global warming potential, and minimized VOC. It can also be used for precision and general industrial cleaning where this enhanced solvency is required.
Vertrel SMT has “zero” ozone-depletion potential, and low global warming potential. It can replace CFC-113, 1,1,1-trichloroethane (1,1,1-TCA), hydrochlorofluorocarbons (HCFCs), and perfluorocarbons (PFCs) in many applications. Vertrel SMT is accepted by the U.S. Environmental Protection Agency under the Significant New Alternatives Policy (SNAP) program, as a substitute for ozone-depleting substances.
Most plastics commonly used for components mounted on printed wiring board assemblies can be safely cleaned. Acrylic, ABS, and poly-carbonate 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. 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.
Vertrel SMT was found compatible with aluminum, copper, and iron, with and without rosin flux present, after exposure for two weeks at 120°C (248°F) in sealed tubes. Large amounts of water may extract alcohol and affect cleaning performance. Therefore, to reduce alcohol loss, use desiccant dryers rather than water separators in the condensate return line.
Vertrel SMT exhibits no closed cup or open cup flash point and is not classified as a flammable liquid by NFPA or DOT. However, the product does exhibit vapor flammability limits in air. Users should clear equipment of all vapors and liquids before performing any maintenance operations that could result in an ignition source. Contact with highly basic process materials, pH 10 or above, is not recommended.
