CAS 127-18-4 Perchloroethylene (PCE, PERC) for Cleaning Solution
Perchloroethylene (PCE or Perc) is a powerful, non-flammable solvent used in industrial cleaning for degreasing metals, precision parts, and as the primary chemical in dry cleaning to remove oils and greases from fabrics without damage.
Key Benefits of Perchloroethylene (PERC) for Metal Cleaning
Strong Solvency
Perchloroethylene PERC is a powerful solvent that easily dissolves grease, oil, and other contaminants from metal surfaces. Its high boiling point and low water solubility make it ideal for cleaning all types of metal parts and components.
Non-Flammable & Safe
Unlike most organic solvents, PERC solvent is non-flammable. It poses no fire or explosion risks when used correctly, making it a safe choice for metal cleaning operations.
Enhances Surface Stability
PERC is perfect for pre-coating or pre-painting surface preparation. It removes all contaminants to create a clean, stable base for protective coatings, boosting the durability and performance of finished metal products.
High Versatility
PCE/Perchloroethylene works well for cleaning a wide range of metal items, including automotive parts, machinery components, electrical connectors, and precision instruments. It fits the needs of various industrial metal cleaning applications.
Efficient Degreasing & Defluxing
PERC cleaning solution quickly removes grease, oils, flux residues, and other common manufacturing contaminants from metal surfaces. It ensures metal products are free of unwanted deposits, maintaining their quality and reliability.
Non-Corrosive Formula
Tetrachloroethylene does not corrode most commonly used industrial metals. It can safely clean and degrease metal parts without damaging their structural integrity.
Fast-Drying Property
PERC evaporates quickly, leaving cleaned metal surfaces dry and ready for further processing or assembly right away. This fast-drying trait also lowers the risk of rust formation on metal parts.
Recyclable & Eco-Friendly
PERC can be recycled and reused multiple times. Proper recycling systems can recover and purify the solvent, cutting down on waste and reducing environmental impact.
