Maintenance Chemicals

ASFOCOAT-BLK is a dark brown liquid which when applied on rusty metallic structures particularly iron & steel surfaces, converts the rust into black protective coating. Even the best paints cannot give full protection if they are applied on steel surface which is not entirely free from rust. Durability of the paint film depends as much upon the quality of the surface to be treated as upon the quality of the paint.

REMOVAL:

If portions of the body or hands become black on account of ASFOCOAT-BLK coating, it can be removed by washing hands with lemon and water.

PACKING: 5 Kgs, 10 Kgs & 35 Kgs.

ASFOSIL is our brand of range of Rust Preventives.

Various rust removing methods such as sand blasting, flame cleaning, wire brushing, grinding by abrasives are not only expensive and tedious but time consuming. Moreover they expose the base metal again to corrosion and rust may reappear even before the primer coating is applied.

ADVANTAGES:

Paints applied over ASFOCOAT-BLK coating are 2 to 3 times more durable when applied on rusty surface. It has very easy application with little labour. No special equipments are needed. Rust removing operations are eliminated & metallic surface is converted into more useful and hard blue black protective coating. ASFOCOAT-BLK is a guarantee of long lasting protection.

ASFOCOAT-BLK is such an active chemical that it reacts in depth with all the rusty layers & forms a protective film which prevents further rust formation. ASFOCOAT-BLK has a triple action on rust.

1. Penetrates through all the rust layers.

2. Reacts with all the rust deposits & converts them to a metal organic compound of a hard blue black colour.

3. Stabilizes and binds the rust layers into a 100% protective neutral coat.

USES OF ASFOCOAT-BLK:

It is particularly recommended for the following:-

Shipbuilding structures, Factory structures, Storage tanks, Heavy machinery and Engineering equipment, Steel frames, Cranes, Pipe lines, Oil Refinery, Steel structures and various other uses, for all rusted surfaces prior to painting or repainting.

METHOD OF APPLICATION:

Oil, grease, dirt and loose paint if present must be removed first, then loose rust must be removed by wire scrubbing or emery paper. ASFOCOAT-BLK is diluted with equal part of water and then applied on the rusted iron or steel surfaces and then allowed to dry.

Water contains various metallic salts in suspension. These metallic salts get accumulated inside pipelines, tubes, etc. in the form of scales over a period of time. These scales must be removed periodically in order to restore the efficiency of system, reduce heating time and attain the required temperature.

SCALGUN SAF LIQUID (SSL) has been formulated mainly for descaling Solar Water Heating System. It is an inhibited acidic composition containing surface active agents and cleaning agents to effectively dissolve and remove all water scale deposits from Copper, Brass, M.S., S.S. and Aluminium tubes, Pipelines and Vessels. Descaling with SCALGUN SAF LIQUID is safe, simple and economical.

DESCALING PROCEDURE:

1. Descaling of Solar Plate Tubes alongwith Storage Tank by CIRCULATION METHOD:

1. Prepare a 10% solution of SCALGUN SAF LIQUID (SSL) v/v (volume by volume) with water in a 50 to 100 litres capacity open top circulating tank (To prepare 100 litres of SSL solution – add 10 litres SSL to 90 litres water). Tank must be made of either Plastic, S.S. or FRP/PVC lined M.S. tank.

1. Connect the outlet of this open top circulating tank by a rubber/plastic hose to the inlet of a 1 or 2 HP S.S./Plastic pump. The outlet of pump should be connected by hose to the drain valve of solar plate. Connect the outlet of the storage tank by hose back to the circulating tank.

1. Start the pump and completely fill the system with SSL solution by circulating the same for 3-4 hours preferably at 45°C.

1. Discard SSL solution and then completely flush the system with plenty of water by circulation till the pH of water reaches 6-7.

1. Descaling of Solar Plate Tubes only without Storage Tank by CIRCULATION Method:

1. Same as 1 (a) above.

1. Same as 1 (b) above – with storage tank disconnected. The return hose pipe to the circulating tank should be connected at union outlet.

1. Same as 1 (c) - without filling storage tank.

1. Same as 1 (d).

SCALGUN-AR-303 is an acidic liquid chemical product used for cleaning cum degreasing of Radiators. It removes light oils along with light scale and rust present on non-ferrous or ferrous surfaces.

PHYSICAL PROPERTIES :

Physical Appearance : Clear colourless liquid free from dirt and insoluble matter.

Odour : Almost nil.

Specific Gravity : 1.05 ??? 0.02

Solubility : Completely soluble in water in all proportions.

pH : less than 2

APPLICATION :

Prepare a 5-10% solution of SCALGUN-AR-303 solution with water in a Plastic tank or container. Dip the Radiators to be cleaned in this solution at 25???C – 60???C for 10 minutes or more depending on the amount of soils present on the surface.

Remove the radiators, then wash off with water and dry or take for further processing as the case may be.

Application for cleaning installed Radiators :

If the Radiators are to be cleaned from inside only then a 5% solution of SCALGUN-AR-303 should be filled completely in the Radiator. Run the engine at idle for 15-20 minutes at room temperature or slightly hot and then discard the solution & flush with plenty of water.

SAFETY PRECAUTIONS :

Wear PVC/Rubber gloves while working with SCALGUN-AR-303.

PACKING : 5 Kgs, 10 Kgs & 30 Kgs HDPE Carboys.

In Paint Spray Booths having water curtain, the oversprayed paint flows with the water as a viscous liquid. This paint tends to adhere to pumps, pipes, nozzles etc. causing it to clog. It also gets through to the exhaust fans, where it coats the fan blades and ducts.

Following are several advantages of adding ‘PAINT ACCUMULATOR’ to the wash water of PAINT BOOTHS :-

1. To prevent clogging

2. To prevent build-up of over-sprayed paints

3. To simplify cleaning operations

4. To reduce maintenance costs.

Application and control is very simple and economical. PAINT ACCUMULATOR is available in two standard packing of 10 kgs and 50 kgs.

EMULSOIL-PL is a metal cleaner consisting of surface active agents, emulsifiers, foam suppresents and anti-corrosive additives. It is a clear homogenous liquid which can be used directly or diluted with Water, Kerosene, and Petroleum Solvents. When diluted with water from 1-30% , it gives a stable milky emulsion. It removes greasy residues, oils, dust and soils very effectively. It does not contain alkalies, acids, phenolic compounds or toxic solvents and hence it is extremely safe to use. It is non-dangerous, non-toxic and non-corrosive. It is suitable for ferrous as well as on non-ferrous metals, sheets, parts or components.

USES :

EMULSOIL–PL can be used for cleaning automotive components, engine blocks, castings, aero & diesel engines. It can also be used for cleaning of industrial floors, exterior shells of cars, buses, railway wagons, aircrafts etc. by means of pressurised hoses. It can be used by hand wiping for cleaning furniture, painted surfaces etc.

OPERATING PARAMETERS

v/v= Volume by volume

If EMULSOIL-PL is used by hot spray, the components will dry immediately and no further washing or rinsing operation is necessary. However an additional drying stage for quicker drying by a blower or compressed air will extend the protection period. The clean components will be resistant to atmospheric oxidation due to the inclusion of Anti-corrosion additives in EMULSOIL-PL. When used at extremely high spray pressures, the addition of EMULSOIL-PL should be made very gradually to the bath while performing the spray cleaning operation. The concentrations should be raised to the desired level over a period of 2-4 hours of operation. The spray parameters stated above will vary depending on the degree and type of contamination and hence these are approximate guidelines. For superior performance our expert advice may be solicited.
