PFAS products that were once widely used in different industrial sectors are now coming under increasing scrutiny due to their long-lasting presence in the environment. NOF Metal Coatings Group has taken this as an opportunity to develop a new PFAS-free top coat range, which includes the PLUS® VLh 2 Silver.
Available worldwide, the PLUS® VLh 2 Silver can be applied to the GEOMET® waterborne zinc flake base coat and meets REACH regulations, as well as European carmaker demands for a stable coefficient of friction on different bearing surfaces, including steel, aluminium or eCoat.
During tightening, PLUS® VLh 2 Silver helps to adjust and obtain the right coefficient of friction according to ISO 16047, which is required by automotive manufacturers. This new topcoat also performs very well on multiple tightening and high-speed tightening, with no stick slip and a promising release torque of 0.08 at 150°C.
In addition to the improved aesthetics with aluminium pigments in the coating, this new PFAS-free topcoat also includes fluorescent pigments for ease of positive identification. Under daylight, all NOF PFAS-free topcoats will have the same silver appearance, but under UV light, the added pigments enable users to easily identify which topcoat has been applied.
NOF METAL COATINGS GROUP also offers other silver and black finishes with specific coefficient of friction, all PFAS-free. All these topcoats are applied via industrial processes and are non-electrolytic to help avoid hydrogen embrittlement, which can cause the cracking of metals.
