DuPont will introduce a new solvent optimized for degreasing metal, glass, plastic and ceramic surfaces.
DuPont will introduce a new solvent optimized for degreasing metal, glass, plastic and ceramic surfaces. Commercialized as Vertrel SDG this product is based on two HFC solvents plus trans-1, 2-dichloroethylene. Vertrel SDG delivers excellent cleaning while remaining nonflammable even though approximately 70% of the ingredients in the product are flammable. It is expected to be an important replacement for all HCFC solvents, many chlorinated applications and older, energy-intensive aqueous cleaners. Vertrel SDG offers exciting performance characteristics. The Kb value and specific gravity are high while the surface tension is low. The product will not mix with water. The Global Warming Potential is 148, about 89% lower than previous formulations. A drop-in replacement for many vapor degreasers, Vertrel SDG will be available mid-summer from MicroCare, DuPont’s authorized source for the Vertrel specialty solvents.
