INTRODUCTION :This process produces a smooth glossy bluish black finish on M.S., ferrous metals and its alloys.Coating thickness obtained is 2 to 3 microns thus it does not alter the dimensions of parts. This typeof finish is very decorative and when sealed in our Rust Preventive it offers long term protectionagainst corrosion and oxidation.

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.

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

We deal in Room Temperature blackening Chemical, which customer can directly avail from us. GENERAL DESCRIPTION VCBLK HB-18 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, energysaving, fast, dependable and convenient. It increases productivity and lowers labour costs.Finishing can be done anywhere without special equipment, ventilation, heating systems or anycomplicated control procedures.EQUIPMENT REQUIREDAcid Resistant tanks, containers, tumbling barrels, baskets, hooks and racks must be used withVCBLK HB-18 and derusting tank. Plastic or Rubber lined tanks and plastic-coated hooks andracks are suitable for both VCBLK HB-18 and derusting tanks. Mild steel may be used fordegreasing, rinsing & sealant tanks.DIRECTIONS FOR USE1. Thoroughly clean and degrease the pieces to be blackened in KLN 18. The type and degree ofsurface soil will determine the length of time and the number of cleaning steps and cleaningtemperature (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 aconcentration 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 6to 12 parts of water depending on alloy and surface, hardness. The immersion time necessary toproduce the desired depth of black, is usually one to three minutes. For most parts a dilution ofone 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). 7. Immerse the pieces in oil, a dewatering type rust preventive at room temperature for 3 minutesto seal the finish and impart corrosion resistance (M.S. Tank).The above parts can be sealed while wet or dry. If parts have to be dried prior to sealing, step 6should be followed with a hot water rinse and the parts to be sealed as soon as they are dry.A wide range of rust preventives are available with us. Consult us on what type of finish andprotection you require for your parts or components and we can suggest a suitable oil.
