DuPont Vertrel® SMT for Traditional Fluxes
DuPont™ Vertrel® SMT is a very aggressive cleaner engineered to remove the ionic soils and organic flux residues of traditional soldering materials often used on electronic assemblies. In side-by-side testing, this powerful new cleaner produced cleaning results equal to the CFC-based benchmark, Freon® TMS. In a test with RMA and RA flux soldered assemblies, Vertrel® SMT gave lower ionics and residual rosin levels when compared to Freon® TMS under identical cleaning cycles. Vertrel® SMT also is effective in removing heavy industrial soils (e.g., mineral oil, vacuum oil, wax and heavy grease) with a brief vapor degreasing cycle. It also can be used for precision and general degreasing where enhanced solvency is required.
