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. Any splashes on skin or eyes should be flushed off with plenty of water and thereafter immediately consult physician. 3. Use of eye goggles and apron is recommended. PACKING : 15 Kgs & 50 Kgs.

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

INTRODUCTION: Degreasing Chemical used whenever parts contains heavy grease, oil & light rust. This chemical also removes certain part of carbon. Base : Alkaline Base Chemical. Solubility : Thoroughly soluble in water. Color : white Concentration : 5% (w/v) is suitable for Hot process & in case of cold 8% required. Point : Concentrated of 8% bath Solution gives 6 to 8 ml. Point. Bath Design : Tank is made up of 10mm thick. M.S. tank with F.R.P. Vinyl coat of F.R.P. Lining works will be the most suitable or sustainable design

Base : Phosphoric Acid Base Chemical.Solubility : Thoroughly soluble in water.Color : Water White.Concentration : One part of chemical is diluted with two to four parts of water DilutionIs depended by the amount of oil present. The chemical is used cold.Point : Concentrated of 25 % bath solution gives 8 to 10 ml.Application : This chemical is used whenever parts contain light grease and OIL.

CHROMATIZING Aluminium chromate and its applications What we call as phosphating to steel an iron is called chromating for aluminium surfaces. Also it is knows as alodine coating. There are yellow, green and transparent chromating types. Yellow chromate coats Cr+6, green chromate coats Cr+3. Coating weight can vary according to application time and coating type. Drying temperature must not pass over 65 º C for yellow chromate and 85 º C for green and transparent chromate coatings. It is importat to provide clean, grease free surface before chromate application. If hot degreasing bath is prepared, caustic bath and following nitric acid bath can be used for pickling. On the other hand, acidic degreasing baths have pickling ability with itselves. Chromating and paint adhesion will be much better on pickled and degreased aluminium surface.

Base : Phosphoric Acid Base Chemical. Solubility : Thoroughly soluble in water. Color : Water White. Concentration : One part of chemical is diluted with two to four parts of water. Dilution Is depended by the amount of oil present. The chemical is used cold. Point : Concentrated of 25 % bath solution gives 8 to 10 ml.
