Nickel Plating Chemicals

Ronuk Industries manufactures a complete range of chemicals for: buffing and polishing, electroplating, phosphating, degreasing, pickling, printed circuit board plating, chemical polishes, and effluent treatment. The company has developed new nickel plating processes which have high levelling ability even at reduced nickel thickness to balance the rising material cost and labour with a view to meeting the demands of customers for better finish. Nickel/chrome plating is still the most widely used decorative electroplated finish on metals. DWA duplex nickel: this duplex system provides semi bright sulphur free levelled nickel deposits with excellent mechanical and corrosion resistant properties and especially suitable for the rigours of a duplex nickel system. Duplex coating of nickel offers considerably higher corrosion resistance and durability, when applied on mild steel at lower thickness. Econik – Duplex nickel process DWA-II: Econik duplex nickel process DWA-II produces non-glaring silky, sulphur free, attractive levelled nickel deposit for rack/barrel plated parts. The added advantage of this system is that after duplex nickel the dragout of bright nickel can be reused in semi bright bath resulting in a high level of economy to the user as close looped system is created due to the brightners and additives of both systems being totally compatible. Marina nickel process: a matt deposit of high speed, easy to manage composition with good chrome receptivity. Large volumes of work and required deposition can be obtained with these salts. Nickel 103 SIXO process: most suitable for barrel plating. Can be operated at minimum 6 V and is a highly conductive salt. There are other processes as well, for various applications.
