Rass-O’-Nil® Flexo is the one-step steel rust preventive deposit 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 coatings. Powder-coating, e-coatings, electroplating, hot dip galvanizing and paint adhere better to the Rass-O’-Nil treated steel surface.
Rass-O’-Nil’s conductive deposit enhances electrostatic bonding for stronger coating adhesion.
Rass-O’-Nil® Rust Preventive Metal Pickling and Treatment:
Rass-O’-Nil makes the metal treatment process faster, economical, and enhances the finish quality.
Rass-O’-Nil Metal Treatment replaces the conventional seven tank process with a clean one-step process. Rass-O’-Nil® Metal Treatment does not produce any effluent.
Rass-O’-Nil steel treatment and pickling saves water because rinsing is eliminated.
Rass-O’-Nil® does not etch the steel surface unlike acid pickling and shot blasting. Rass-O’-Nil prevents hydrogen embrittlement of metal caused by acids like hydrochloric or sulphuric acid.
The Rass-O’-Nil steel pickling process eliminates hazardous/toxic chemicals, such as strong acid.
Metal Corrosion Prevention Quality:
The Rass-O’-Nil treated metal surface sealed with a finish coat withstood more than 900 hours of salt spray test, 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, prevent corrosion beneath powder coating, e-coating, paint, and galvanizing.
High Performance Metal Finish Coating Adhesion:
Rass-O’-Nil enhances 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® 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® increases paint adhesion.
The Rass-O’-Nil® treated metal surface improves the metal life cycle during storage and transport of high sulphur content oil in pipelines and tanks.
The Haldia Petrochemicals Refinery and the Unilever Soap Factory in India have found Rass-O’-Nil to be very useful in their maintenance operations before finish painting.
RASS-O’-NIL ONE-STEP 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
Rass-O’-Nil® Metal Surface Coverage and Economy:
One kilogram Rass-O’-Nil covers up to 750 square feet on new hot rolled steel and up to 960 square feet on new cold rolled steel. Rass-O’-Nil is priced at US $ 10 /- (Dollar Ten) and ₹ 780/- (Rupees Seven Hundred and Eighty in India) per kg packed in ten litre HDPE Drums and one kilogram bottles.
