Chemicals / Conversion Coating / Phosphating & Nano Ceramic Coatings
Phosphating & Nano Ceramic Coatings
Phosphate coatings are predominantly applied to ferrous metals. However, it is also used Zinc and Aluminium for some specific applications. These coatings on its own are insufficiently protective for treated metal surfaces but excellent as pretreatment before painting, powder coating, impregnation with enamels, lacquers, oils and waxes. The coating is thin and adherent to the substrate metal whilst being porous and insulating. Consequently, the coating permits “keying” or mechanical interlocking of applied paint film whilst the electrical inertness of coating localise corrosion beneath adjacent unbroken painted areas of the base metal surface. Phosphate coatings may be produced by immersion, brush or spray, since surface conversion depends only on contact between substrate and phosphating solution. These coatings are also used in cold forming operations such as drawing, stamping and cold extraction operations.
Surklin 101/ 102/ 103
Surklin series cleaners are medium duty caustic free alkaline cleaners used for spray/dip cleaning of ferrous and galvanised articles. They contain bio-degradable surfactants with better emulsification / saponification and operate at lower concentration, time and temperature, thus have longer bath life.
Surpickle 501/502
Non-flammable phosphoric acid based pickling media to remove rust, scale, oil and grease. Pickle aid accelerator are added to accelerate effective removal of hardened scales.
Surpickle BR/ Surfix MPT 1/2/3
Removes moderate amount of oil, rust and provides an iron-phosphate film by brush or wipe on. It is economical since single product is used to remove rust, oil and provide iron phosphate film on the surface, therefore mainly recommended as an under-coat prior to painting.
Surfix Fe 691/ 695
Surfix Fe system is an iron phosphating chemical process for spray or immersion application. Mild Steel, Galvanised Steel and Aluminium can be processed in this chemical. Surfix Fe treatment converts metal surface to a amorphous iron phos- phate coating, for corrosion resistance and increases adhesion and durability of paint finishes. These products can also be used in combination with Surklin 112, being a pack of bio-degradable surfactant, combina- tion acting as a cleaner coater system.
Surfix ECO 100
Surfix ECO 100 is new generation nano ceramic coating substitute for Iron Phosphating, being free from phosphate, COD or BOD. The process operates at ambient temperature and does not generate sludge during reaction with substrate. It is suitable for multi-metal application such as treatment of Mild Steel, Galvanised steel and Aluminium surface. The process operates at ambient temperature and provides an ideal base for subsequent powder coating / painting.
Surcon 301 Z/ 302 Z/ SURCON Mn 321 / 322
These surface conditioning chemicals are for metal phosphating with better bath stability. These promote formation of uniform, dense and finely crystalline phosphate coatings which are preferred base for paint and have superior corrosion resistance. These products are used for both ~ Zinc & Manganese phosphating.
Surfix ZN 601/613 /635
These products produce smooth, microcrystalline fine grained uniform Zinc-Calcium- Phosphate coatings ensure excellent bond between paint and base metal. Calcium modified Zinc phosphate also provides ideal base for rubber to metal bonding; coating Wt. 200-400 mg/ sq.ft., meeting IS specifi- cation 3618/1966 CLASS A/B.
Surfix ZN 605/ 615 /610
These are tri-cationic Zinc phosphating products are formulated for dip / spray mode of applications. These chemicals are suitable for processing Mild Steel, Galvanised Steel surface and Aluminium, latter by using specific additives. This treatment converts metal surface to a nonmetallic, fine-crystal, Zinc phosphate coating, which inhibits corrosion and increases adhesion and durability of CED primer and other paint finishes.
SURFIX ZN 604 / 604 M
These are Zinc & Nickel based di-cationic phosphating products for mulated on immersion application Mild Steel, Galvanised Steel can be processed in the chemicals at ambient temperature.
Surfix Zn 602 / 603 /617 / 620 / 625 / 611 / 640
These products impart heavy Zinc phosphate coatings, ideal for metal forming application such as tube drawing, wire drawing, cold heading and also recommended for corrosion protection of fasteners with rust preventive oil. Coating Wt. 750-2000 mg/sq.ft. meeting IS specification 3618/1966 CLASS A.
Bondlube BC
Used over heavy zinc phosphate coating to influence the lubrication property. Hence, this is quite successful in post phosphating applications like wire & tube drawing.
Surfix MN 641 / 643
This product impart a non-metallic, oil absorptive, crystalline, black / dark-grey Manganese-Iron phosphate coating on steel and iron surfaces to reduce wear and prevent galling of moving parts, such as bearing surfaces like includes pistons, piston rings, shafts, gears, cylinders and all types of machine parts wherever wear is a constant factor to be considered. Coating Wt. 750-3000 mg /sq.ft, meets IS specification 3618/1966 CLASS A.
Surseal 701 / 706 / Ginthox NCR 60
These chrome/ non-chrome products are added to final rinse after phosphating to improve corrosion resistance of the phosphate coat and adhesion with subsequent coat of paint.
Brightening of stainless steel fastener, threaded bars, nuts etc. can be done with this process, involving cleaning, removal of scales, surface conditioning and brightening; finish can be retained by providing coat of wax on surface.
Steelex K 20 MVP
This is a heavy duty alkaline cleaner designed for cleaning of different grades of Stainless Steel. It rapidly wets metal surfaces and displaces oils/ greases/shop soils leaving work clean and ready for further processing.
SURPICKEL 506 MVP / SURKLIN 112 A
These mixed products are acid base chemicals specially designed for treating stainless steel components before polishing, combination effectively removes mild oxide layer which is present on surface to obtain uniform itching.
Surklin 112 B
This product is a blend of different surfactants which helps in brightening/ polishing of different grades of stainless steel, giving brightness promoting passive layer over the surface.
Gictane PASS 3013 / Surseal SS 717
This is a sulfur & halogenes free passivation for martensitic stainless steel and a critical step in maximising inherent corrosion resistance of the stainless steel. It is neither a scale removal treatment nor a coat of paint. Gictane PASS 3013 can remove surface contamination from work piece & maximise corrosion resistance of stainless steel.
Surseal 718(BAR)
Passivator for stainless steel, specially designed to improve the acid resistance & hence,, very successful for the components within the vicinity of battery acid.
