Sunenergy System,S.L. applies a zinc and nickel alloy coating to its products, which provides very good cathodic protection against corrosion and is applied by means of an alkaline electrolyte; it admits passivation, as well as sealants. ZnNi+SELL has many applications in many fields of industry, such as automotive, machine building, aeronautics, solar trackers, silos and greenhouses.
Examples of applications of this coating:
- Threaded fastening elements for which high resistance to corrosion and thermal resistance are required, such as joints with temperature loads of up to 150ºC in the engine compartment of vehicles and brakes, as well as chassis joints.
- Pipe joint accessories such as fittings, bushings, flanges and valves for hydraulic systems.
- Applications of adhesion of rubber on metal. – Unions that require electrical conductivity. – Steel fasteners in contact with aluminium.
