ANTI-CORROSION CHEMICAL COATING COMPOUND
costly machineries & structral steels to save high cost of replacements

Our Research Organisation has successfully developed a special Class of Co-polymer
Plastic Based Anti-Corrosion Coating Compounds through exhaustive work
conducted over several years. This is quite a new Class of
products, not placed in the market ever before by any Manufacturer and hence, we claim
these as our Monopoly products.
Since last ten
years, we are marketing these Anti - Corrosion Coating Compounds on a large scale and to a
great satisfaction of our Customers. The product takes, an excellent bonding with Metal
surfaces and offers a very good protection against corrosion resulting from a wide range
of industrial chemicals, gases and adverse weather conditions.
The products are variously
coloured and their coatings almost look like those of paints.
|THE TERM "ANTI-CORROSION PAINT":
Since paints are devised for protecting metal surfaces, it is broadly
believed that all paints are anti-corrosion paints. But it is not a correct version. All
oil-based paints, for example, are not anti-corrosion paints. They are merely
decorative paints which protect the metal surface partially against the climatic corrosion
but fail to stand against the drastic corrosion caused by various industrial chemicals
exist in the World over Fifteen Million known chemicals of Organic & Inorganic origin.
Hence it is obvious that there cannot exist a single, all - purpose, Anti-corrosion paint
or Coating material that can effectively combat the corrosions resulting from such a wide
range of chemicals. Thus, Anti-Corrosion Paint itself is a loosely defined
term that gives no clear promise for an effective and versatile anti-corrosion effect.
Our Anti-corrosion Compounds are SINGLE-PACK, ready-to-use products which
do not require the addition of a Hardener / Catalyst at the time of use, as it is
necessary in the case of Polyurethane and Epoxy classes of anti- corrosion paints.
For application of our products, the laborious and expensive
method of sandblasting for cleaning the rusted metal surface is not necessary.
Just a thorough manual cleaning with metal sharpnels & steel-wire brushes is enough.
Though CORREPEL possesses a unique self priming property, the use of our
special Primer is recommended to produce a durable coating. However, in the absence of our
Primer, a suitable Zinc Phosphate / Zinc Chromate primer can be used.
The components of our Anti-corrosion Compound chemically react and set
into a stiff Co-polymer
plastic laminate through inter-molecular cross-linkages and takes a strong
bonding with the clean metal surface. The resultant coating is impermeable to air &
VERY IMPORTANT: The most spectacular feature of our
Products is that owing to the excellent solvation property, the well-stuck part of the old
coating re-softens and completely merges with the new coating to produce a single
consolidated coating at the time of next application.
while cleaning, do not remove the well-stuck part of the old coating off the metal surface
at the time of next application. Just apply a fresh coating over the well-stuck old
coating to produce an even coating. Thus, the continued use of CORREPEL ultimately
produces such a tough coating on the metal surface which latest very long and becomes
extremely resistant to the drastic conditions of corrosion. The coating effectively
protects metal structures against the corrosion of saline weather conditions in coastal
Besides metals, our Coating Compounds give an excellent bonding with
concrete surfaces. The product components in solution penetrate into the porous concrete
surface through absorption and form plastic tentacles within the substrate which firmly
hold the coating to afford an extra strong bonding with the concrete surface. The coating
prevents erosion of the concrete by weather, water, chemicals and gases.
The coating prevents the growth of fungus, moss, algae and other
vegetative as well as bacterial life.
||The heat tolerance temperature of the coating is about 125-135
||Coverage of CORREPEL: Two Litres of the
material give TWO coatings on about 65-70 Sq.Ft. area of the metal surface, previously
coated with a Primer.
Coverage of our A.C. Primer: One Litre of the Primer gives ONE
coating on about 65-70 Sq.Ft. area of the cleaned metal surface. Dry Film Thickness:
Collective DFT of Primer & Two coatings of CORREPEL is about 125-140 Microns. (1 Mil =
0.025 mm = 25 Microns)
||Minimum Self-life of the A.C. Coating Compound in well closed
containers is about 12 Months.
Products are supplied in about Thirty fixed shades in 20LTR & 5LTR packings. However,
products in any other colour- choice of the Customers can be made and supplied as a
special Order ( At least 500 L) against their shade sample, of course subject to the
possibility of doing so without sacrificing the anti-corrosion property of the Compound.
|METHOD OF APPLICATION
Remove the thick scales of rust on the metal surface with mild hammer
strokes and clean out the surface thoroughly by scratching with metal sharpnels and
steel-wire brushes. Then remove the loose rust particles on the metal surface by rubbing
with dry cloth. Remove the stains of grease or oils, if any, on the metal surface by
cleaning with kerosene or petrol.
that the cleaned metal surface is completely dry before application On the clean and dry
metal surface, first give a coating of our special Primer or a suitable Zinc
Phosphate/Zinc Chromate Primer and allow to dry for one day. Shake the Compound in the
container very well. Give two even coatings of the material with nylon brushes, each
coating at an interval of one day Please mark, our Products being Solvent- based, the
first coating does not give a complete hiding of the lower surface. The final coating,
however, produces a total hiding of the lower surface. While giving the coatings, do not
unduly rub the brush for a long time over the same spot. This leads to the formation of
plastic fibres on the brush which disturb the coating with the pulling effect. In fact,
this is a peculiar property of our Co-polymer Compounds.
fibres again take a little fresh material or thinner on the brush and make an even
coating. The surface of the coating becomes replica rolex tack-free within six hours and dries up
completely within 24 hours. Total hard drying through complete cross-linkages of the Co-polymer
takes about a week.
1) At the end of use, quickly wash out the used brushes with our Thinner
2) If the Compound/Primer becomes thick due to solvent-loss through
improper capping of the containers, thin it as necessary by adding to it our Thinner or
Xylene. Do not use Turpentine, kerosene or oils for thinning since they spoil the
3) Though commercial quality Xylene is available in chemical markets, our
speicial Thinner will be supplied to the users as per their need.
While making the Primer/Compound application in non-ventilated or poorly ventilated
conditions, arrange a powerful Exhaust Fan to evacuate the solvent vapours and protect the
workmen from suffocation. Avoid flames and smoking to save from fire or explosion while
working under such closed - conditions. It is, however, advised to avoid the applications
in closed conditions.
