VANGUARD RC

Functions at temperature range of: 65 to 70 deg. C.  In about 3 to 5 minutes' of dip duration, forms velvet-smooth, dense, very hard and crystalline calcium modified zinc phosphate coating. The Coating wt: between 250 and 400 mg/s.ft. It is an Ideal base for subsequent painting liquid paint, powder coating,

The Calcium present acts as the in-built grain refiner in the phosphating bath and hence eliminates the need for a separate activation or a titanium pre-rinse step. Thus, the introduction of calcium not only results in the formation of coatings of good quality, but also contributes to the economy of the process through the elimination of the pre-rinse process stage.

This  is a combination of 3 cations namely, ZINC, Manganese and Nickel all in a fixed combined proportion.Technically speaking this is the best form of phosphating available. This gives excellent results even at lower temperatures. This the coating is smooth and gives excellent corrosion resistance in a salt spray chamber with low micron build up.

Guardclean- AL

Etching is a process for revealing the structure of the material. The common etching techniques include:

• Chemical, Electrolytic, Thermal, Plasma, Molten salt, Magnetic

The two most common techniques are chemical and electrochemical etching. Chemical etching is typically a combination of either an acid or base with an oxidizing or reducing agent in a solute. Guardclean AL is one such product which does chemical etching.

Guardclean-AL  is a specially compounded formulation for use on most of aluminum alloys. When used as recommended, it will produce smoothly etched surfaces, free from pits or other evidence of irregular etching actions.It is based on acids and works at room temperature.

Guardclean-AL  etches the surface in seconds and hence care should be taken to remove the pieces on time. 

Usage Instructions: The tanks to hold on the etchant should either be made of ms and lined with FRP or of a good quality plastic.  Fill the tank half with water.  Then add Guardclean AL to the tank at 1/10^th of the working volume.  {If the working volume of the tank is 100 litres then add 10 litres of Guardclean AL}.  Mix the bath.  Add water to make it to the working volume.  Then stir well to make the bath homogenous.

All the parts that are to me etched must be chemically cleaned to insure the best results out of the etchant.  Normally the etching will be done within 30 seconds.  It is for the user department to arrive at the exact time required to etch their components.  Immediately after etching the parts should be rinsed in water thoroughly.

Disposal:  Use and dispose of product, container, residue etc in accordance with all local laws and regulations.

ALUPHOS  is a single shot cleaner to clean and surface preparation for aluminum. Can also be brushed.  Good for cleaning large areas like bus body, control panels etc.,

It is the process by which the metal is given a black or bluish coating.  Normally it is the ferrous and aluminium components that are blackened.  Our brand name is jettalizer.

JETTALIZER ( Hot Black Oxidizing Chemical)

Black oxide coatings are chemical conversion coatings, applied as a protective or decorative finish. Black oxide coatings have properties that make them ideal for certain applications.   They are suited for moving parts or sliding surfaces that cannot tolerate the dimensional build-up of the more corrosion-resistant finishes. JETTALIZER bath operates at between 136 and 143 Degrees C.

Black oxide coatings are used in a wide variety of applications and industries. Applications include firearms, aerospace and military components, automotive parts and engines, camera components, spark plugs, machine tools, aircraft turbines, furniture, sporting goods, internal gears, and other components which are well-lubricated, such as screws, nuts, washers, and other fasteners. The coatings present a pleasing black appearance frequently employed, in addition to protection, for decorative purposes or decrease in light reflection.

Koldblak functions at 20^o+ C.  It blackens steel and cast iron components.  Cold blackening process is simple and safe to operate and produce high quality results. 

Koldblak forms a copper selenide coating, which when sealed with appropriate oil, wax, etc will provide corrosion resistance to the treated components.  Comes in liquid and gel form.

PICKLER SS

Pickling is the removal of any high temperature scale and any adjacent low chromium layer of metal from the surface of stainless steel by chemical means. The lower chromium content gives lower corrosion resistance. To restore the best corrosion resistant performance, the damaged metal layer must be removed, exposing a fully alloyed stainless steel surface. Pickling solutions also remove contaminants such as ferrous and ferric oxide particles. All pickling operations result in metal removal, and the outcome is therefore to some degree a dulling of the visual brightness and perhaps also a significant reduction in dimensions.

For components which can be dipped you can use liquid Pickler SS. 

Pickler SS also comes as paste form. It is a very convenient method for pickling Stainless Steel. This is a prepared mix in a stiff paste which enables it to be applied to small areas and to vertical or even overhanging surfaces. It is especially useful for pickling to remove heat tint following welding, the underlying chromium depleted layer as well as residual slag in 10-45 minutes. 

PASSIFIER SS

If passivation is not carried out, stainless steel can rust due to surface free iron, and since chlorides are also often absorbed from the atmosphere, some ferric chloride will be produced. Prolonged contact with ferric chloride will eventually initiate pitting and crevice corrosion on the stainless steel surface.

PASSIFYER SS enhances the passivation process in a more uniform manner to restore the chrome oxide film and help to prevent future corrosion following installation of the fabricated product. It is used at room temperature, as supplied or can be diluted with one part of water.  The time duration varies from  30 minutes to 60 minutes.

PASSIFYER SS  also comes both in liquid and paste form.

Albrite

{ Acid based aluminium brightener }

Albrite is an extremely strong mixture of acid solution for tough fleet cleaning jobs of aluminum!  It is ideal to use as part of a two-step process. Leaves aluminum with a soft satin sheen, too.

Albrite is also highly effective in cleaning stainless steel. Aluminium Cleaner removes corrosion products and oxide films with minimal attack on the substrate and reduced localised pitting. 

Cupbradip

Chromate-free, liquid chemical polish for brightening

Copper, brass and bronze by immersion application

Cupbradip is a chromate-free, highly acidic liquid chemical polish, used for brightening old and tarnished copper, brass and bronze parts.  It can be used to brighten all kinds of copper and copper-alloyed parts Including light fixtures, copper contact terminals, brass fittings and valves, meters, gauges, regulator parts and building hardware.

Cupbradip eliminates time-consuming, tiresome, manual polishing and buffing of intricately and irregularly shaped parts with “nooks and corners”.  When the  metal surfaces that have been thoroughly precleaned of all contaminants is immersed in the Cupbradip at room temperature, the acidic liquid polish chemically dissolves and removes oxides, stains, tarnish and discolorations, from copper or brass and its alloys and a clear, metallic brightness is restored.  After thorough fresh water rinse, it leaves the bare-metal clean and shiny bright.  Then, to give the surfaces long-term indoor protection from retarnishing, the metal parts are rinsed and then immediately dipped in Cupbradip-F.

Cupbradip-F inhibitor is a mildly alkaline liquid tarnish - preventing agent that is specially formulated to provide longterm protection.  The special blend organic salts guards copper, brass and bronze parts against tarnishing, oxidation and corrosion after they have been chemically polished by Cupbradip.

Application procedure:

First remove all oil, grease, paint and lacquer from parts by precleaning them with a suitable alkaline cleaner such as Thelnikal LD. If parts are covered with hard water scale, they should be descaled with a suitable descalant, such as KWIKSHOT, and thoroughly rinsed.

Once the contaminanats are removed, the parts are immersed in Cupbradip, as supplied, at room temperature.  The durtion of dip depends on the amount of stain and tarnish to be removed and surface finish. Follow with thorough fresh water rinse.

 Then, to give parts long-term indoor protection from retarnishing, oxidation and corrosion, they should be  immediately immersed in a solution of Cupbradip-F at 10%  by volume for 30 seconds at room temperature.  Follow with thorough water rinse and air dry.
