L553A is a sophisticated, non-ionic surfactant blend engineered by Ruqinba Group for high-demand industrial spray cleaning applications.
L553A is a sophisticated, non-ionic surfactant blend engineered by Ruqinba Group for high-demand industrial spray cleaning applications. It combines advanced isomeric alcohol ethoxylates with ethylene oxide-propylene oxide (EO-PO) block copolymers. This synergistic formulation provides exceptional penetration and wetting properties while maintaining a "foam-free" profile under normal pressure spraying. Specifically optimized for acidic environments, L553A is the premier choice for removing stubborn grease from metal hard surfaces without leaving residues.
Superior Low-Foam Performance: Specifically designed for spray systems where foam control is critical. It remains stable and low-foaming even in high-shear conditions.
Exceptional Wetting & Penetration: The isomeric alcohol backbone ensures rapid displacement of aged oils and complex grease layers.
High Acid Resistance: Formulated to maintain peak cleaning efficiency in various common acidic cleaning agents (up to 10% acid concentration).
Excellent Water Rinsability: Ensures a residue-free finish, preventing secondary pollution and making it ideal for pre-treatment lines (plating, coating).
Low-Temperature Stability: With a freezing point below -10.0°C, it remains easy to handle and store in cold industrial environments.
Eco-Friendly: Safe for operators and compliant with modern environmental standards.

L553A is highly versatile and widely used in the following sectors:
Automated Spray Cleaning: For low-foam, high-pressure industrial parts washing.
Acidic Degreasing Formulations: The core active ingredient for formulating acidic metal cleaners and rust removers.
Hard Surface Cleaning: Deep removal of stubborn mineral oils and processing fluids from steel, alloys, and hardware.
Pre-treatment Processing: Essential for achieving high surface energy required for subsequent electroplating or coating.
Packaging: 200KG/drum and 1000KG/drum (IBC Tank).
Shelf Life: 18 months from the date of manufacture.
Storage: Store in a cool, dry place, away from acids and water. Transport as a general non-hazardous chemical.
