Promtech Chemicals Pvt. Ltd. and Innovative Coating Industries offer the rust converter RUSTOFIX 1411 and ZINKOTE -20 zinc rich paints/coatings for mild steel engineering fabrications and structures. Both products are developed on the latest technology available and offer outstanding corrosion resistance life for the coated structures. The combination coating have passed 1,000 hours of fog chamber salt spray test and can resist every type of corrosion, including marine and salty atmospheres to chemical fumes and high humidity conditions.

Surface preparations
The preparation for rusted and non-rusted steel (C sections, I beams and pipes/angles used for all heavy engineering fabrication) is done by complete removal of oil and grease (if present) and a light wire brushing to remove the existing loose rust (oxides of iron).

RUSTOFIX 1411
Apply one coat of RUSTOFIX 1411, a rust converter cum rust preventive cum a primer coat. This has a good adhesion on all types of steel and provides a 12-15 micron primer coating which is bluish, brown and black. Since this takes the iron metal to its last form (adherent rust is converted to ferrosoferric oxide, an inert complex, and forms a barrier coating, allowing no more rusting of steel due to atmospheric oxygen or moisture in atmosphere.)

Water-based RUSTOFIX 1411 contains complex (chelating) agents, driers, levelling agents, preservatives and polymerisation boosters. It dries in 10-15 minutes and is non flammable. It covers 120 sq. feet per litre. Rusted MS Panel Rustofix 1411 Rustofix + Zinkote

RUSTOFIX 1411 can be used by spray/dip, brush and swabbing. The black coating is absolutely adherent and shall not be washed. This coating dries within 8 hours and can be overcoated after 24 hours. Subsequent coating is optional. Steel will remain rust protected even after this single application. Overcoating with any high-grade paint, zinc-rich paints, CRPs, epoxies and modified alkyd paints will increase anticorrosion life of the metal.

ZINKOTE 20
The rust-converted steel shall be overcoated with ZINKOTE 20, a zinc-rich paint used for cold galvanising touch-up. ZINKOTE 20 is manufactured by use of pure acrylic resin and 99 per cent pure zinc metal flakes which have horizontal packing in the dry film. Zinc metal, being extremely passive to any chemical action or oxidation, completely stops any further corrosion or attack of atmospheric oxygen, saline water, humidity in air, or chemical vapours and fumes on the coated steel sections and fabrication.

Its single coat offers 18-20 microns of zinc and double coat, if necessary, may be applied after 24 hours. ZINKOTE 20 is an instant air-drying paint; hence, unused tins should be always tightly closed to avoid losses due to evaporation. The coating shall confirm to most of the requirements of national as well as international standards.

ZINC BRIGHT in 500 millilitre aerosol format also offers silver bright finish cold galvanising on damaged/ scratched galvanised surfaces.
