Steel Coil Coating Treatment Service

Rass-O’-Nil® Flexo is the one-step clean steel coil treatment nano-technology. Rass-O’-Nil treats the metal and deposits an ultra-fine conductive metallurgical poly-phosphate deposit on the metal. Rass-O’-Nil Flexo is a cold dry coat treatment to apply metallurgical conductive nano-deposit on CRCA steel. Rass-O’-Nil Flexo eliminates rust preventive oil, degreasing, phosphating, chromate washing, zinc phosphate and water rinsing. Rass-O’-Nil Flexo improves the colour coating’s bonding to the steel and adhesion with the treated metal surface and protects the treated metal from corrosion over a long time. Rass-O’-Nil®-Flexo is an organo-metallic ester grafted with metallurgical metal oxide (ions) in binary form and is deposited through nano particle size coating into the steel substrate’s micro-structure. Rass-O’-Nil Flexo deposit on the steel surface was found to be dense, and uniform with a deposit weight of 0.05 to 1.7 gm2. Steel Treatment Quality: The Rass-O’-Nil Flexo 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 the adhesion test. Rass-O’-Nil stringently satisfies ASTM B117 and IS: 13515-1992 (Indian Standard). The Rass-O’-Nil treated metal surface can withstand thermal shock up to 400° C, and random bending up to 180°.
