TOP COATS INORGANIC · ORGANIC
Surface protection coating consisting of Zn and Al sheets joined by an inorganic binder that acts as a sacrificial metal. Due to the application characteristics of this coating, it does not present hydrogenation brittleness, therefore, it is recommended for high resistance screws (10.9 and higher).
By applying TOP COATS on the basis of ZnAl, it is possible to increase the resistance to corrosion and parameterise the coefficient of friction for each of the specifications. Our mass application is made by means of centrifuges specially designed for a greater uniformity in the coating, as well as to avoid accumulations. In accordance with the environmental conservation policy, all the lamella processes applied are chromium-free.
