PAINTING of SOLAR POWER PLANTS
Structural Galvanized Steel Fabrications
Structural MILD STEEL Fabrications
: Recommended Process :
Greetings from Prof PRADEEP VAIDYA : CEO :
PROMTECH GROUP. Innovative Coating Industries,
MIDC Pimpri; PUNE, our manufacturing unit offers the
following Products for De-Greasing, De-Rusting
Chemicals used by Dipping / Brushing Process at Room
Temp. The time for total cleaning is accomplished
within 20 to 60 minutes.
PRECLEANING / SURFACE PREPERATION
BEFORE PAINTING : It is most essential to
completely clean all the Oil, loose Rust, Dust, dirt
grease & foreign matters form inside, outside of the
Steel Tubes, Angles, Channels , Metal and Fabrications.
POST PAINTING ANTI CORROSION DEPENDS GROSSLY
UPON THE TOTAL AND COMPLETE PRE-CLEANING.
MOST IMPROTANT FACTs on use HYDROCHORIC
ACID Based De-Rusting: Never use HYDROCHLORIC ACID
for MS or GI Tubes Pickling. Though very fast in cleaning, the
acid will surely leave Residual Acid ions, in the Micro-pores
and crevices of the metal surface. This phenomenon is called
as HYDROGEN EMBRITTLEMENT. This causeS POST
CLEANING CORROSION ( Sub-Surface Corrosion ) on the
metal. RUSTING WILL TAKE PLACE with DOUBLE THE SPEED .
Re-Rusting can happen from one day to 60 days. Rusting will
take place BELOW PAINT/ Coating Film ( Creeping Corrosion )
The chloride fumes are continuously generated from HCl and
these fumes pose a great HEALTH HAZARD to the operators,
will corrode the Steel structures, Building Trusses, Metal
Buildings, Chimney , Steel stored in the nearly vicinity of this
Metal Cleaning / Pickling area. These fumes spread
Hydrogen Chloride ions in the atmosphere and are very
dangerous to mucous membrane and lungs and will prove as
a very serious health hazard. These fumes will be extremely
detrimental to the overall functioning of the Equipments.
Salvage costs will prove to be phenomenal in this case.
PROCESS for CARBON STEEL / MILD STEEL &
GALVANIZED Steel Structural Fabrications:
( 1 ) RUSTOGEL 1406 : RUST CLEANING & REMOVAL
Process by BRUSHING APPLICATION : The VERTICAL &
Standing Galvanized Steel Structures, Support
Structures, get rusted due to OXIDATION in Humid,
Damp & Moisture in the Atmosphere. This Rust MUST BE
REMOVED before applying any kind of Paint. RUSTOGEL
is a Phosphoric Acid based DERUSTING GEL (Viscous
Brushable Liquid). It is applied by Brushing all over the
Rested MS / GI Fabrication. It is allowed to react with
the rust for 10 to15 Min. This Loosens the rust. This
treated surface is Water Washed neatly and
IMMEDIATLE Dried by using Compressed Air Blow. The
structure MUST BE PAINTED WITHIN 8 Hours. RUSTOGEL
is a water based Acidic Cleaner, is RoHS Compliant &
Safe for Workmen. RUSTOGEL is offered at Rs 70 Per
Kg in 35 Kg HDPE Carbuos Packing+Vat Ex Pune works.
IMPORTANT : Derusting Process by using OIL BASED
Chemicals ( viz: WD 40 or similar ) are VERY SLOW in
Rust Removal ( There is NO CHEMICAL ETCHING for Rust
Removal & may need 4 hrs to 24 Hrs for moderate rust
removal ). Oil based Chemical Cleaners are basically
RUST PREVENTIVES, Apart from slow action, these
cleaners also Leave a OIL BARRIER Coating on the
treated Surface. Due to Oil film, this will totally MAR
ADHESION for any PAINT/COATING ( Zinc Rich Paint
coating in this Case ). Hence Oil Based Cleaners are
NOT RECOMMENDED for such Applications which
involve Painting process, post De-Rusting.
( 2 ) POST CLEANING RUST PREVENTIVES
Application : Work In Progress Corrosion Protection
For all such structures which are Not to be Painted
and are required JUST TO BE STORED in the Yard :
All Carbon Steel Fabrications , & Raw Steel, which have
WIP Period of upto 3 months shall be coated with a
very light layer of Oil-Based Rust Preventive. We offer
AQUANIL DWO : Dewatering Oil cum Wet Film type
Rust Preventive. This is available for Rs 145 per Litre
+++ Ex our Works in 35 Ltrs HDPE Carbuoys.
( 3) ZINC RICH PAINTS / ZINC METAL SPRAYS
These products offer a uniform ZINC METAL POWDER
Coating on all MS and Galvanized metal . When used
as recommended, ZINC RICH PAINTS offer 15 to 20
years of Total Corrosion Free surface. We offer FOUR
PRODUCTS in this range. ZINKOTE 20 GP & PREMIUM
Grades are offered in 20 Litres Packing ( Rs 390 & Rs
630 Resp.) Zinc Metal Spray ( Light Grey Finish ) 500 ml
Aerosol is Offered for Rs 275 / Can and Zinc Bright
Spray ( Silver Bright Finish ) 500 ml Aerosol is Offered
for Rs 320 / Can Ex Pune & Thane.
Products offered for DERUSTING / Pre-Cleaning
BULK QUANTITY OFFER : We offer Discounted
Price to our Bulk Qty Buyers. Offered Discounted
Prices based on One time Purchase Quantity, ( 100
Aerosol Spray Cans or 100 Litres of ZINKOTE Paints.)
SALIENT Features, Quality Standards & USP
These Paints / Sprays confirm to the requirements of
most Indian, British and ASTM Specifications. These
Paints offer 20 to 25 Microns Film, 88 to 92 % Zinc
in the DFT, Zinc Purity of 99% +. Pass 500 Hrs Salt
Spray (15 yrs + in the Normal weather conditions )
Pass Cross Cut Hatch Test for Adhesion as per IS
Specs. Complete details on all these Tech properties
are available in our Literatures / Website.
Approvals & Recommendations Our Zinc Rich
Paints are Approved, Used and Recommended to their
vendors & Fabricators by RIL, REIL, NPCIL, L& T, BARC
IIT, EIL, S&P, DOKA, Thermax, TATA, St Gobein, SIGMA
BGR Energy, ZENTIH, INDUS Towers 25+ EPC / INFRA
Firms & by NABL Accredited Test Lab from Mumbai
Safety Pre-Cautions : During entire Pickling ,Cleaning &
Painting Process, every operator / Worker MUST use all the
Safety gear, Goggles , Rubber Aprons, Gum Boots, Handgloves etc. In case of Spillage / Splashing of any of the
treatment chemicals, flush the affected area with plenty of
running water for 2-5 minutes.
Effluent Treatment : All wash Waters, Floor Swipping,
Splashings of Chemicals must be neutralized by adding LIME
WATER, ALKALINE Water, Alkaline Waste. Final pH of outgoing water must be maintained between 7 to 8.5.
All our offered products are RoHS compliant, extremely safe
for workmen & confirm to requirements of IS , ASTM & BS
Specs. In case you need any additional Information, please
feel free to call / Email me. Thanks & Warm regards:
