Aluminium degreasing with mild alkaline liquid and powder products

BONDERITE® aluminium 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 aluminium and ultrasonic cleaners.

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

Aluminium degreasing is the first step in the process chain

Aluminium degreasing is a very important step in a multi-stage aluminium 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 aluminium and can blacken the surface. In addition, the types of mill lubricants, cutting oils, and stamping compounds used on aluminium are different to those found on steel.

Therefore, it is important to use a special aluminium 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 the technology.
