Importance of Understanding the Chemicals Used in the 7 Tank Process for Powder Coating Before we delve into the types of chemicals utilized in the 7-tank process, let\\'s first explore the significance of understanding them. Knowledge about these chemicals empowers engineers, technicians, and industry professionals to make informed decisions at each stage of the process. Understanding the characteristics, applications, and potential risks associated with different chemicals is crucial. Conversion Coating Chemicals in 7-Tank Process Chemicals Conversion coating chemicals play a crucial role in the highly effective 7-tank process, providing an essential step in the surface preparation of various metals. Their significance lies in their ability to enhance the durability and corrosion resistance of the materials they are applied to. conversion coating chemicals are an indispensable part of any metal finishing process. The types of conversion coating chemicals used are diverse, including phosphate-based, chromate-based, and zirconium-based coatings. Each type offers unique qualities and benefits, ensuring excellent adhesion and surface protection. These chemicals form a thin, uniform layer on the metal surface, which not only acte as a barrier against corrosion but also facilitat adhesion of subsequent coatings, such as Privacy Terms powder coating. · By zinc-based metals we mean zinc itself and alloys of zinc with minor proportions of other alloying materials, together with those impurities known to the art to occur therein. For example the metal may be zinc sheet, formed zinc strip or zinc-based die-casting alloys, typically containing 90 percent or more by weight of zinc. Alternatively the metal surface to be treated may be a zinc coating applied to an iron or steel substrated, for example by hot dipping or electrodeposition and usually referred to as galvanized iron or steel. The zinc surface may also be passivated by, for example, subjecting it to the action of an aqueous solution of certain chromium salts, to further increase its corrosion resistance. · Metal surfaces of the above type are frequently found to provide unfavorable surfaces on which to deposit paint films, a commonly observed defect being that of poor adhesion between the paint and the metal substrate. · It has been proposed to pretreat the surface of zinc-based metals prior to painting them by subjecting the surface to the action of a chemical solution which deposits an adherent crystalline zinc phosphate conversion coating thereon. The process usually involves a precleaning stage and optionally a water rinse to remove dirt and/or oily residues from the surface prior to its chemical treatment. The phosphate coating is believed to have a beneficial keying action on paint coatings applied to its surface, thus improving the paint to metal adhesion. Although this treatment has given satisfactory results in many instances, there still exist circumstances in which the adhesion between the metal surface and the paint coating may fall short of acceptable commercial standards.

1. ZNP-54 ZINC PHOSPHATING CHEMICAL 2. Generally zinc phosphate conversion coating is used to provide long lasting corrosion protection. Almost all automotive industries use this type of conversion coating. It is suitable for the products come against hard weather conditions. Coating quality is better than iron phosphate coating. It forms 2 - 5 gr/m² coating on the metal surface when used as under paint. Application, set up and control of this process are more difficult than other methods and can be applied by immersion or spray. 3. Organic compounds like nickel and manganese are added to the bath to increase the coating performance. Also activation can be used to form small phosphate crystals on the metal surface before zinc phosphating. 4. Zinc phosphate reaction happens in amorphous shape with gray - black color. 5. pH optimizers are added to accelerate the reaction. Temperature, application time, concentration, pH, total acid and free acid values are the parameters which must be under control. 6. Zinc phosphates, coating range between 7 - 15 gr/m², are used in wire drawing, tube drawing and cold forming industries. Phosphated metal workpieces are prepared to the next stage by application of protective lubricans and soap

VC AR306 INTRODUCTION : VC AR306 is a powder based activator which is used at low concentrations prior to zinc phosphating. By dipping the parts in VC AR306 bath prior to phosphating, it accelerates the subsequent phosphating process and also refines the structure of the zinc phosphate coating resulting in smooth fine uniform compact coating. PROPERTIES : Colour : White Form : Free flowing powder PH of 0.2-0.3% : 8-9 APPLICATION : VC AR306 bath can be prepared in M.S. or plastic tank/container. It is to be used at 0.2% to 0.3% concentration with water, at room temperature for one minute. The bath should always be kept in a slightly agitated condition by mechanical means or by passing compressed air from the bottom of the tank to avoid settling of the activator at the bottom of the tank. MAINTENANCE OF BATH : Once the bath is prepared, daily addition should be made once during the day. Addition should be made when pH falls below 8. Always maintain pH between 8-9. New bath should be prepared once in week or once in 15 days, depending on the work load. PRECAUTION : 1. Since the product is alkaline in nature always wear PVC/Rubber gloves while handling or working with this product. 2.
