A REVOLUTION IN CORROSION PREVENTION
From Decay to Durability: Coatings that Redefine Corrosion Prevention
MEET METGUARD
A CONCEPTUAL ADVANCE IN METAL PROTECTION
Metguard is a unique metal passivating protective coating, arresting corrosion of metals at its core. Challenging conventional norms, Metguard offers a cost effective, greener & technologically advanced solution to corrosion prevention.

UNIQUE METAL PASSIVATION TECHNOLOGY
Metguard works on the principle of metal passivation. Unlike conventional protective technologies that primarily offer mere barrier protection, Metguard possesses the remarkable capability to passivate active metals, suppressing their reactivity with the environment, and arresting corrosion at its core.
Metals have a natural propensity to ‘lose’ themselves in an electrolyte which migrates to the coating-metal interface through limited pathways of any protective coating during exposure. This causes metal loss enfeebling structures and continues undetected till coating is detached due to pressure of corrosion products. METGUARD transforms the interface through a unique chemisorption of inert polymeric segments on it during ongoing exposure to harsh environmental conditions, arresting metal loss through anodic metal dissolution. Notably, passivation is achieved on all metal substrates without accessing bare “white metal. This phenomenon eliminates underfilm corrosion and extends the life of structures exponentially, offering enhanced protection in much thinner films.
NEW HORIZONS
NO ABRASIVE BLASTING NEEDED
Say goodbye to sand/shot/grit blasting—Metguard provides unmatched corrosion protection without any complex surface preparation, for both existing corroded, as well as new structures.
LOWEST LIFECYCLE COSTS
Metguard minimizes lifecycle costs by virtually eliminating active metal loss through in situ passivation at the coating-metal interface, reducing metal scrappage and replacement. Its perfect recoatability after years of service ensures easy and cost-effective maintenance.
ENHANCES LIFE OF METALLIZED STEEL
Duplex coatings on non-blasted and non pre-treated galvanized steel (HDG), Galvalume, aluminium alloys arrest depletion of reactive metal such as zinc etc. ensuring extended galvanic protection of steel, greatly extending life of metalized steel especially in acidic/alkaline exposures.

WHERE THERE IS METAL, THERE IS METGUARD
CAN BE APPLIED ON:
All new steel structures in stockyards and fabrication centers (including tubular structures like pipes)
All existing corroded steel structures
Galvanized/ Zinc-aluminium Sheets & Structures (New & existing corroded)
Stainless & other ferrous alloy structures (New & existing corroded)
Concrete embedded steel structures: re-bars, etc
IN VARIOUS INDUSTRIES SUCH AS:
POTENTIAL APPLICATIONS
- Replacement of hot dip galvanized steel structures especially in acidic / alkaline areas
- Reduction of material & energy costs in cathodic protection through thin film coatings on steel
SIMPLE & EASY APPLICATION
Clean the metal surface
No blasting is required here. Nominal surface preparation, including wire/ brush cleaning will suffice.
Follow mixing instructions
Open the Metguard cans and follow the simple mixing instructions provided.
Apply on metal surface
Apply Metguard coatings directly on the metal surface, even if it is already rusted. Application can be done by brush/spray/roller/ airless/pneumatic gun.
Stop Corrosion
Wait for proper drying and stop the corrosion of metals completely.
CAN BE APPLIED DIRECTLY ON RUSTED SURFACE
Metguard can be applied directly on rusted surfaces without the need for extensive surface preparation. Only the removal of loose rust will suffice, making it a highly efficient and cost-effective solution for corrosion protection.
NO ELABORATE MAINTENANCE
Easy recoatability requiring minimum surface preparation, only recoating the top coat at specified intervals will suffice. No need to remove existing coating like in other coatings.
COAT IN ANY WAY, IN ANY COLOUR
Brush
Roller
Spray/ Airless Gun
LOWEST LIFECYCLE COST
SAVE BY ALMOST 100%
- Lower operational cost as no blast cleaning required.
- Lower maintenance cost as only top coat is to be re-applied. Thus, lesser paint requirement & lower labour cost in future.
- Significant long-term savings in cost as negligible metal scrappage.
- Enhanced workplace safety.
- No disruptions in production.
