MRC -- Henkel, a surface treatment provider, expands its production capacities in Montornes del Valles, Spain, adding solvent- and chromium-free innovations for the pretreatment of metals in coating plants to its European portfolio, said the company.
Henkel 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. The agents act as an interface between the steel and the coating to provide enhanced corrosion protection and adhesion.
The three solutions are now also available as solvent-free products with the suffix 'SF' (solvent-free). For example, one disadvantage of solvent-borne products is their boiling point of 150 degC, which leads to poorer drying of the material. In contrast, users of the solvent-free, odourless and better-drying solutions benefit from process-related advantages, such as greater product stability at higher temperatures.
The solutions also have a much longer shelf life, as precipitation during storage is reduced. To meet the demand for solvent-free pretreatment products, Henkel has invested significantly in its Montornes site in Spain to expand production facilities for the polymer used in these products. This polymer gives the products their outstanding properties in terms of coating adhesion and corrosion resistance. The site is ideally positioned in terms of infrastructure to serve as the European hub for coil pretreatment, while also increasing capacity for global customers.
We remind, Henkel acquired the US-based Critica Infrastructure (“Critica”), a specialized supplier of maintenance, repair and overhaul (MRO) composite solutions for the world’s most critical infrastructure such as oil and gas transmission as well as municipal water supply systems. Critica is active in many countries with a strong focus on North America and is expected to reach sales of around 100 million euros (around 110 million USD) in 2023.
