Product Description
BONDERITE® C-AK 909 is a moderately alkaline powdered cleaner formulated for degreasing heavily soiled metal surfaces without attacking the underlying substrate. Suitable for steel, copper, zinc, aluminum, stainless steel, titanium, and other metals, it is used during surface preparation before chemical conversion coatings, electroplating, welding, metal brightening, and other finishing operations. The cleaner offers strong chelating and surface-tension-reducing properties while remaining free of caustic soda, and can be applied by immersion or ultrasonic cleaning.
Key Features
- Multi-metal compatibility: Suitable for steel, copper, zinc, aluminum, stainless steel, titanium, and other metals.
- Moderately alkaline formulation: Degreases heavily soiled metal surfaces without attacking the substrate.
- Strong cleaning chemistry: Combines chelating and surface-tension-reducing properties for effective contaminant removal.
