Rass-O’-Nil® is the one-step steel rust preventive treatment nano-technology. Rass-O’-Nil deposits a conductive polymerised metallic phosphate nano-deposit. Rass-O’-Nil removes rust.
The Rass-O’-Nil Flexo nano-deposit protects metal from rust below finish coatings. Powder-coating, e-coatings, electroplating, hot dip galvanizing and paint adhere better to the Rass-O’-Nil Flexo treated steel surface. Rass-O’-Nil’s conductive deposit enhances electrostatic bonding for stronger coating adhesion. Rass-O’-Nil makes the metal treatment process faster, economical, and enhances the finish quality.
Rass-O’-Nil® Steel Treatment does not produce any waste and or need water. The Rass-O’-Nil steel treatment and pickling process saves water because rinsing is eliminated. Rass-O’-Nil Steel Treatment reduces carbon emission because the conventional seven tank process is replaced with a clean one-step process. The Rass-O’-Nil steel process eliminates all the hazardous/toxic chemicals, such as strong acid.
Rass-O’-Nil® Flexo Metal Protection Quality
- The Rass-O’-Nil treated metal surface sealed with a finish coat withstood more than 900 hours of salt spray test and passed the 1.5 kg scratch test, and adhesion test.
- Rass-O’-Nil stringently satisfies ASTM B117 (USA) and IS: 13515-1992 (Indian Standard).
- The Rass-O’-Nil deposit does not come off from the steel even when the metal is bent up to 180°, punched, drilled or heated up to 400° C.
- Rass-O’-Nil treated metal surfaces, sealed with a finish coat, left in the open atmospheric conditions for years, do not allow corrosion beneath powder coating, e-coating, paint, and galvanizing.
Rass-O’-Nil Flexo Protects Steel in Saline Conditions
Rass-O’-Nil ® technology protects structural and fabricated steel surface and the finish coating from corrosion on ocean transit. Rass-O’-Nil enhances the coat’s adhesion to the metal and protects the metal from corrosion in harsh conditions.
Rass-O’-Nil Flexo conductive metallic deposit protects offshore and onshore steel infrastructure in hydrocarbon and maritime industry.
Rass-O’-Nil Flexo deposit enhances the finish coating adhesion to the metal, protects the steel from rust in saline, acidic, and alkaline environments, and improves the finish coating or paint’s quality. Rass-O’-Nil ® protects structural and fabricated steel and powder coating, e-coating, electroplating and paint from corrosion on ocean transit and weathering.
Rass-O’-Nil® Flexo treatment on the steel surface of oil wells and the plates of tanks helps the topcoat on the metal withstand aggressive weathering. Rass-O’-Nil® Flexo increases paint adhesion.
The Rass-O’-Nil® Flexo treated metal surface improves the metal life cycle during storage and transport of high sulphur content oil. Rass-O’-Nil treated inner surface of pipes helps improve the flow of oil inside the pipeline system.
RASS-O’-NIL ONE-STEP CLEAN METAL TREATMENT TECHNOLOGY WAS TRIED AT TATA STEEL UNDER AGREEMENT:
“For several years — Tata Steel’s R&D and Roy Research and Technology made a joint effort towards the optimization of the chemical’s uses and physical testing for plant implementation for the development of the metal surface preparation and pre-treatment technology through lab and plant trial. This metal surface preparation and pre-treatment technology polymerised with a polymorphous character.
For several years — Tata Steel’s R&D invested considerable amounts towards adapting the new technologies and Roy Research and Technology has also invested certain amounts and time in developing these technologies.
After thorough testing at the lab and plant level, these new technologies were well which accepted by Tata Steel and Roy Research and Technology. The following are those technologies are the new developments of poly-phosphating and poly-metallic phosphate – Flexo and Galvo Technologies for HR, CR, Galvanneal, and tubes (hereinafter referred to as New Technologies.)” Excerpt from text of Agreement.
Title- A method for poly phosphate coating on rolled steel sheet to resist corrosion.
Joint effort towards the optimization of the chemicals used and physical and patented publication date 27/04/2007, post grant journal date u/s 43(2) 07/05/2007, granted patent 235627 add as green steel with benefit of carbon reduction, no degreasing needed and carbon reduction credits
