Two major French OEMs approve Zintek? 200 SL F?
BERLIN, Germany April 2020: Atotech’s two-coat system, Zintek? 200 SL F, has been approved to meet French OEM standards for protection of fastener systems.
“Atotech’s zinc flake coatings provide advanced corrosion protection and fulfill the requirements of a substantial number of OEM specifications. Featuring high corrosion protection, controlled friction properties and a reduced number of coating layers, Zintek? 200 SL F represents a cost-efficient solution, perfectly in line with the French OEMs’ demanding requirements,” explains Jean-Louis Baudoin, Atotech OEM Manager France, who was leading the approval project.
In addition to its very good adhesion properties Atotech’s Zintek? 200 SL F shows an excellent cathodic corrosion protection. According to the standards for protection of fastener systems, a coating must maintain corrosion resistance in the neutral salt spray test (ISO 9227) without base metal corrosion, for at least 600 hours. Zintek? 200 SL F exceeds this, lasting for more than 1000 hours without corroding.
Unlike conventional anti-corrosion systems, which are based on zinc flake coatings consisting of two base coat layers and one top coat layer, Atotech’s Zintek? 200 SL F system saves one layer by incorporating just two self-lubricated corrosion protection layers that provide a controlled coefficient of friction (CoF). Compared to a three-coat-system, the silver base coat two-layer system with integrated lubricant enables a lower deviation of coefficients of friction, giving a centered COF in the range of 0.12 to 0.18.
Zintek? 200 SL F fulfills friction requirements defined by both OEMs on diverse materials, such as aluminum, galvanized steel and e-coated steel. Even with two lubricated layers the Zintek? 200 SL F solution does not exhibit a “stick-slip” effect. Thus, the system is recommended for the coating of safety labeled fasteners and parts.
Features and benefits of Zintek? 200 SL F
- Industry proven two-coat system approved for standards?for protection of fastener systems
