Solvent- and chromium-free pretreatment solutions by Henkel Adhesive Technologies

For more than 25 years, Henkel Adhesive Technologies has been supplying the chromium-free pretreatment agents Bonderite M-NT 1455T, M-NT 1456, and M-NT 10456 for coil coating to customers in various sectors, such as architecture. These agents act as an interface between the steel and the coating to provide enhanced corrosion protection and adhesion. The three solutions are also available as solvent-free products with the suffix "SF" (solvent-free).

One disadvantage of solvent-borne products is their boiling point of 150 degrees Celsius, which leads to poorer drying of the material. In contrast, users of solvent-free, odorless, and better-drying solutions benefit from process-related advantages, such as greater product stability at higher temperatures. These solutions also have a much longer shelf life, as precipitation during storage is reduced.

Henkel’s pretreatment technologies also support the upcoming transition for tinplate manufacturers, who have to eliminate chromium from their processes by 2027.
