Blackening Chemicals Application is a new revolutionary development in cold black finishing. It will impart jet black conversion coating to steels, cast iron and other ferrous metals at room-temperature. VCBLK HB-18 process is easy to do in-house. It is non-caustic, non-splattering, safe, energy saving, fast, dependable and convenient. It increases productivity and lowers labour costs. Finishing can be done anywhere without special equipment, ventilation, heating systems or any complicated control procedures. EQUIPMENT REQUIRED Acid Resistant tanks, containers, tumbling barrels, baskets, hooks and racks must be used with VCBLK HB-18 and derusting tank. Plastic or Rubber lined tanks and plastic-coated hooks and racks are suitable for both VCBLK HB-18 and derusting tanks. Mild steel may be used for degreasing, rinsing & sealant tanks. DIRECTIONS FOR USE 1. Thoroughly clean and degrease the pieces to be blackened in KLN 18. The type and degree of surface soil will determine the length of time and the number of cleaning steps and cleaning temperature (M.S. Tank). 2. Rinse thoroughly in overflowing cold water (M.S. Tank). 3. Surface rust, if present, should be removed following cleaning cycle using RLN 27 at a concentration of 1:1 at room temperature (FRP Tank). 4. Rinse thoroughly in overflowing cold water (M.S. Tank). 5. Immerse the pieces in VCBLK HB-18 solution. VCBLK HB-18 solution is to be diluted with 6 to 12 parts of water depending on alloy and surface, hardness. The immersion time necessary to produce the desired depth of black, is usually one to three minutes. For most parts a dilution of one part VCBLK HB-18 with 9 parts of water would give good results (FRP Tank). 6. Rinse the pieces in overflowing cold water for 30 seconds (M.S. Tank).

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

DESCRIPTION : VCCLEAN-550 is a very effective deburring compound. It can also be used for cleaning, degreasing, derusting, descaling etc. when used in tumblers, vibrators, agitators and deburring equipments. It will remove all loose deposits producing a very smooth and even surface on the components. It can very safely be used for ferrous as well as non-ferrous metals. It is non-toxic and very safe to handle. USES : 1. For deburring ferrous & non-ferrous components. 2. For removal of rust & scales from components when used in tumblers & vibrators etc. alongwith some suitable media APPLICATION :- 1. Add 5-10% of VCCLEAN-550 based on the water added to the tank of the vibrator/tumbler etc. 2. Operate the equipment for a time ranging from ½ hr – 6 hrs depending on the type of operation. Regular addition of chemical may have ro be made for long duration of operation 3. Rinse tumble the components with fresh water. 4. Dip them in a suitable rust preventive like RUST PREVENTIVE OIL depending on the desired period of protection.

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.

RUST CONVERTER CHEMICAL Paints applied over VITARAG CHEMICALS coating are 2 to 3 times more durable when applied on rusty surface. It has very easy application with little labour. No special equipments are needed. Rust removing operations are eliminated & metallic surface is converted into more useful and hard blue black protective coating. VITARAG CHEMICALS is a guarantee of long lasting protection. VITARAG CHEMICALS is such an active chemical that it reacts in depth with all the rusty layers & forms a protective film which prevents further rust formation. VITARAG CHEMICALS has a triple action on rust. 1) Penetrates through all the rust layers. 2) Reacts with all the rust deposits & converts them to a metal organic compound of a hard blue black colour. 3) Stabilizes and binds the rust layers into a 100% protective neutral coat.
