The new Bonderite C-AK 24600 from Henkel boosts efficiency and sustainability in aluminium alkaline etching, saving energy and increasing performances.
The specialty chemicals manufacturer Henkel has recently presented Bonderite C-AK 24600, a new solution specifically developed to either save energy or increase alkaline etching performances during the pre-treatment of aluminium for architectural applications.
As a matter of fact, depending on the configuration of the system configuration, the user can either
increase the etching rate while maintaining the same application temperature or reduce it while maintaining the same etching performances.
Alkaline etching allows to create a rough surface that ensures the adhesion and the performances of the subsequent conversion coating. Traditionally, users have achieved the highest etching performances at a higher temperature, consuming a lot of energy. The new product Bonderite C-AK 24600 from Henkel allows to reduce the temperature by up to 7 °C while still achieving the required etching rate – saving more than 0.5 tons of CO2 in natural gas per cubic meter of bath.
“Bonderite C-AK 24600 shows how innovation in the chemical industry can help reduce environmental impact and increase efficiency in the production chain. We are enabling our customers to achieve their sustainability goals, such as energy savings, or in other words, to achieve more with less. This was not possible with previously available products because they required a higher temperature to achieve the desired performance,” has stated Cristina Acedo, the senior product development manager of Henkel.
