Nickel

Electrolytic Nickel plating, the backbone of plating industry, is extensively used all over the world for decorative & corrosion resistance applications. It is often used as undercoat to provide a bright and levelled surface before plating of precious metals. Improvisation over the years with special additives has made the system highly versatile and job oriented.

Topbrite 771 Bright Nickel Process
A contemporary top-of-the-line high performance process for rack/barrel plating; excels in every trait of Nickel plating systems. A highly concentrated bright- ener to be used in conjunction with Topbrite Additive
221 in controlled quantities. Highly recommended where quality is of prime concern.

Bright Nickel Processes Spectra 77 / 77BL / 177 / 973 / 977 / 977T / 979 / 981 / 991 / 999 / 979M / 986 / 2977 BL Brightener
The spectra range of brighteners is a highly advanced system of Nickel brighteners. They produce brilliant, highly levelled and ductile deposits. Suitable for a very wide range of operation, they perform best in conjunction with Nickel Additive 22 / 220 / 22M / 232. They are suited for rack and barrel operations. Special mention of Spectra 77BL, Spectra 997 BL, Unispec 8, Spectra 177 & Spectra 2977 BL for capability of produc- ing bright lustrous & exceptionally highly levelled nickel deposit in barrel plating process.

Superglo Brightener 33 / 93 G Bright Nickel Process
A widely used versatile bright Nickel system which produces very quick bright levelled deposits. Highly tolerant to variations in temperature and bath concen- trations. Offers excellent low current density cover- age. Suitable for manual vat and barrel installations.

Zenith 95 Bright Nickel
Primarily developed as a techno-commercially economical system. Produces ductile bright and highly leveled deposits, at lower brightener consump- tion.

Unispec Gi 6 / 16 / 99 /C 110 / 786 Processes
New generation bright Nickel additive system suitable in rack & barrel plating process. Unispec 99 brightener system contain a special type primary brightener, so it can be chosen as a single additive system. Unispec C
110 is highly concentrated secondary bright-nickel brightener system suitable in combination with Nickel Additive 22 / 232 to produce high degree of levelling, considerably reduces consumption of secondary brightener making it economical to the users. Unispec 6, 16 & 18 are the recent addition to this series of Nickel brighteners, specially developed for producing highly levelled bright deposit at lower brightener consump- tion.

Spectra 190 / 3070 Brightener
A unique ultra high performance Nickel brightener- system produces superb glossy levelled fully ductile Nickel deposit and thus Nickel Chrome plated compo- nents look eye appealing bluish, thus, makes the plated articles attractive to the users.

Esbee Semi-Bright Nickel Process
A coumarin free advanced semibright Nickel system. Produces levelled semi-bright sulphur free base coat in multilayer Nickel deposits with excellent mechanical and corro- sion resistance properties.

Ductolite Semi-Bright Nickel Process
A highly advanced and latest development to produce ductile, highly levelled, semi-bright sulphur free Nickel deposit. Higher STEP pattern - potential difference between bright & semi-bright layer is achieved even upto 140 mv.

Ductolite Tri Nickel Process
Used as a sandwich layer between semi-bright and bright layer in a 3 triplex Nickel plating system. Has far superior (1.5 times) corrosion resistance properties when compared to duplex Nickel Chrome deposit of identical deposit thickness Builds a sulphur rich Nickel layer below the top surface to inhibit corrosion penetrating top and bottom layers.

Ductolite MC 180 Nickel
Used as a sandwich layer between bright and followed by, conventional chrome layer (0.3-0.5 microns) in a multi-layer (3 & /or 4 layers) Nickel plating system. This layer induces microcrackks Nickel layer across the whole working current density range. Hence, if chrome coating is applied on top this uniform microcracked Nickel layer, it becomes ideal microcrack Nickel Chrome coating - easily meets automotive requirements. Has far superior (1.5 times) corrosion resistance properties when compared to duplex Nickel Chrome deposit with identical plating thickness. In a practical field test this process is found to be quite successful to offer better result in the “Russian Mud Test”.

Ductolite MPS 170 Nickel Process
Used as a sandwich layer between bright and followed by conventional chrome layer (0.3-0.5 microns) in a (3 & / or 4 layers) Nickelplating system. This layer induces microporosity in Nickel layer (>10000 pores per sq. cm), across the whole working current density range. Hence, if chrome coating is applied on top this uniform microporous Nickel layer, it becomes ideal microporous Nickel Chrome coating - easily meets automotive requirements. Has far superior (1.5 times) corrosion resistance properties when compared to duplex Nickel Chrome deposit with identical plating thickness. Highly suitable to improve corrosion resistance in CASS test.

Pearlsheen Nickel Process
Produces neat, silky, stain free, highly decorative nickel deposit with satin finish. Suitable for rack plated components.

Edenmatt Emulsion Developer/Pearlsheen Additive 1249 / 1449 / 7-K-9
New generation organic additive to produce bright silky grained satin effect.
Nickel Purifier An insoluble filter media for use in filter packs to remove metallic impurities from Nickel plating bath solutions. Regular use of this product will keep plating bath virtually free of metallic impurities, thus assuring maximum brightness of electroplated Nickel and also eliminates costly downtime, high pH treatments and dummying.

Nickel Additive 22 / 22M / 222B / 220 / 232 / 262
A universal primary make-up brightener to be used in conjunction with the above mentioned bright Nickel systems. Increases tolerance to impurities and enhances brightness and ductility when added in a regulated manner in bright Nickel processes.

Nickel Leveller 44 / 244 / 246 / UNISPEC
Leveller 247 / 248
Special additives compatible with our bright nickel processes to impart additional levelling Ideally suited for poorly polished surfaces.

Nickel Additive 34 / 42 / 52 / 5868S
A purifier for bright Nickel systems to improve tolerance to metallic impurities like dissolved copper and zinc.

Growel Anthracite Nickel Plating Process
An excellent cyanide free Nickel alloy plating process to be applied as an overlay on bright Nickel to produce eye-appealing glossy ‘bluish black anthracite finish.

Groblack Black Nickel Process
Produces decorative black finish of Nickel.

Universal Dull Nickel Process
General purpose dull Nickel plating process which is simple to operate, economical and easy to control.
