Innovative Coating Industries manufacturing unit offers the following products for de-greasing, de-rusting chemicals used by dipping and brushing process at room temp. The time for total cleaning is accomplished within 20 to 60 minutes.

Pre cleaning and surface preparation before painting: It is most essential to completely clean all the oil, loose rust, dust, dirt grease and foreign matters form inside, outside of the steel tubes, angles channels, metal and fabrications. Post painting anti-corrosion depends grossly upon the total and complete pre cleaning.

Hydrochloric acid based de-rusting: Some of the most important facts on use Hydrochoric acid based de-rusting are: Never use Hydrochloric acid for MS or GI tubes pickling. Though very fast in cleaning, the acid will surely leave residual acid ions, in the micro-pores and crevices of the metal surface. This phenomenon is called as Hydrogen Embrittlement. This causes post cleaning corrosion (Sub-Surface Corrosion) on the metal. Rusting will take place with double the speed. Re-rusting can happen from 1 day to 60 days. Rusting will take place below paint or coating film (Creeping Corrosion). The chloride fumes are continuously generated from HCl and these fumes pose a great health hazard to the operators, will corrode the steel structures, building trusses, metal buildings, chimney, steel stored in the nearly vicinity of this metal cleaning and pickling area. These fumes spread Hydrogen Chloride ions in the atmosphere and are very dangerous to mucous membrane and lungs and will prove as a very serious health hazard. These fumes will be extremely detrimental to the overall functioning of the equipment. Salvage costs will prove to be phenomenal in this case.

Process for carbon steel, mild steel and galvanised steel structural fabrications:
RUSTOGEL 1406
Rust cleaning and removal process by brushing application: The vertical and standing galvanised steel structures, support structures, get rusted due to oxidation in humid, damp and moisture in the atmosphere. This rust must be removed before applying any kind of paint. RUSTOGEL is a phosphoric acid based de-rusting gel (Viscous Brushable Liquid). It is applied by brushing all over the rested MS/GI fabrication. It is allowed to react with the rust for 10 to15 minutes. This helps loosen the rust. This treated surface is water washed neatly and immediately dried by using compressed air blow. The structure must be painted within eight hours. RUSTOGEL is water based acidic cleaner, is RoHS compliant and is safe for workmen.
Also de-rusting process by using oil based chemicals namely WD 40 or similar are very slow in rust removal (there is no chemical etching for rust removal and may need four to 24 hours for moderate rust removal). Oil based chemical cleaners are basically rust preventives, apart from slow action, these cleaners also leave a oil barrier coating on the treated surface. Hence oil based cleaners are not recommended for such applications which involve painting process, post de-rusting.

Zinc rich paints and zinc metal sprays
These products offer a uniform zinc metal powder coating on all MS and galvanised metal. When used as recommended, Zinc rich paints offer 15 to 20 years of total corrosion free surface. The company offers four products in this range and they are Zinkote 20 GP, Premium, Tefkote 21 (PTFE teflon blended zinc rich paints grades are offered in 20 litres packing can. Thinner for zinc rich paints: Toluene, Xylene, stoving (Bhatti). Thinner or NC thinner number one or two. Do not use GP thinner/MTO. This will gel with paint.

Salient features
Quality standards and USP: These paints and sprays confirm to the requirements of most Indian, British and ASTM specifications. These paints offer 20 to 25 microns film, 88 to 92 per cent zinc in the DFT, zinc purity of 99 per cent. Pass 500 hours salt spray (more than 15 years in the normal weather conditions). Pass cross cut hatch test for adhesion as per IS specifications.

Approvals and recommendations: The company’s zinc rich paints are approved, used and recommended to their vendors and fabricators by RIL, REIL, NPCIL, L&T, BARC IIT, EIL, S&P, DOKA, Thermax, TATA, St Gobain, SIGMA BGR Energy, ZENTIH, INDUS Towers, and more than 25 EPC/INFRA Firms and by NABL accredited test lab from Mumbai.

Effluent treatment: All wash waters, floor swipping, splashings of chemicals must be neutralised by adding lime water, alkaline water, and alkaline waste. Final pH of out-going water must be maintained between 7 to 8.5.

All the company’s offered products are RoHS compliant, extremely safe for workman and confirm to requirements of IS , ASTM and BS specifications. n
