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.

INTRODUCTION: This hot oxidising process produces a smooth, glossy, jet black finish on M.S., Ferrousmetals and some of its alloys. This black finish is very decorative and when sealed properlywith a suitable rust preventive like RUST PREVENTIVE OIL, it affords lustre and longterm protection to the parts against corrosion and oxidation.

Blackening Services For Metal Parts 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).

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.
