• Paints, Coatings and Finishes

Electro Coating is a corrosion resistant coating, which follows the method of depositing a film of organic coating using electric current to deposit the paint. The process works on the principal of "Opposites Attract". An electro coat system applies electric charge to the metal part immersed in a bath of oppositely charged paint particles. The paint particles are drawn to the metal part where an electrochemical reaction takes place forming an even, continuous film over the complete surface. At the desired film thickness, the film insulates the part and electro coating stops. Cathodic coatings are high performance coatings with excellent corrosion resistance. This process is environment friendly, can sustain 1000 hours of salt spray in accordance to test standard ASTM B 117, can coat intricate and recessed areas, has transfer efficiency better than 95%, is a water based technology, has fewer defects, predictable costs because coating can be controlled within 5 microns, better finish since the film is reproducible from part to part and from day to day and has reduced labour costs. However it has three shortcomings. Only electrically conductive substrates can be processed, colour change is not possible and initial capital cost is substantial. The company is offering CED coating systems for epoxy black and gray coatings at an affordable price. To design a system the volume of the tank and the surface area to be coated is required. Each system is designed keeping in mind the exact requirements of the customer. Since most of the crucial components are imported it takes up to 12 weeks to deliver the system. Components can be sent for sampling.
