Aluminum degreasing with mild alkaline liquid and powder products

BONDERITE® aluminum degreasers are developed specifically for the removal of contaminates such as oils, magnesium oxide and polishing pastes. BONDERITE® degreasers are borate and silicate-free and suitable for high gloss aluminum, such as for ultrasounds.

BONDERITE® degreasers support a very large temperature range and boost paint and lacquer adhesion.

Aluminum degreasing is the first step in the process chain

Aluminum degreasing is a very important step in a multi-stage aluminum process and is key before starting any other mechanical or chemical process.

Heavy-duty alkaline and caustic-based cleaners commonly used to clean steel will partially dissolve aluminum and can blacken the surface. In addition, the types of mill lubricants, cutting oils, and stamping compounds used on aluminum are different to those found on steel.

Therefore, it is important to use a special aluminum degreaser to ensure proper surface characteristics for maximum paint adhesion. BONDERITE® supplies degreasers in alkaline, neutral and acidic formulas, immersion or ultrasonic methods. Using an optimised cleaning product will substantially improve operational processes, saving time, money and energy.

Henkel assists customers closely and monitors the process through technical visits to ensure the strong performance of technology.
