High-performance, chrome-free corrosion protection for automotive, wind energy, railways, solar and construction — delivered from five plants and 13+ coating lines, monitored by AI-enabled quality systems. Our core application is zinc flake coating for fasteners — high-strength bolts, studs, nuts and special parts for automotive and industrial assembly.
A look inside India's largest zinc flake job coating facilities — the people, the lines and the technology behind every protected part.
Established in 2005, Aum Dacro Coatings is one of the pioneers of zinc flake coating in India — a licensee of NOF Coatings Asia Pacific, Japan, combining deep technical expertise with the country's largest zinc flake application footprint.
Alkaline & solvent cleaning, rinsing and controlled drying strip oils and residues — and rule out hydrogen embrittlement on high-strength fasteners.
Table, hanger, tumble and sand shot-blasting activate the surface for superior adhesion, matched to each component's geometry.
GEOMET® zinc flake applied by spray, rack or bulk dip-spin and dip-drain — a uniform 8–12 µm film of overlapping zinc-aluminium flakes.
Thermal curing bonds the lamellar layers into a hard, stable, sacrificial barrier with full corrosion and thermal resistance.
100% visual and analytical inspection — XRF thickness, adhesion, curing and friction checks — with every compliant lot barcode trace-tagged.
In-house XRF, optical microscopy, salt spray and CoF testing validate every batch to ISO 10683, ASTM B117 and ISO 9227.
Non-electrolytic, chrome-free anticorrosion systems built from overlapping zinc and aluminium lamellae. Thin, uniform, dimensionally stable — and with zero risk of hydrogen embrittlement, the trusted choice for high-strength fasteners.

Our strength lies in deep technical know-how backed by strong global partnerships. We collaborate with leading OEMs and technology providers to deliver advanced coating solutions that meet international standards — ensuring consistent quality, innovation and reliability.
We measure success through the voices of our customers. Featured stories and case studies highlight real-world results — faster deliveries, consistent performance and lasting partnerships. True excellence is achieved by delivering more value, every time.
Every facility runs on digital traceability, barcode tracking and real-time data systems. AI-driven dashboards predict quality deviations, optimise chemical usage and ensure zero rework — making Aum Dacro not just a coating company, but a digital manufacturing partner.
ISO 9001:2015, IATF 16949:2016, ISO 14001:2015, ISO 45001:2018, VDA 6.3 — and the prestigious AIAG CQI-12 Version 3 compliance covering pretreatment, dip-spin, zinc flake coating and curing.
Aum Dacro collaborates with international leaders like NOF Metal Coatings Japan and MCS Japan to bring next-generation coating technologies and efficiency standards to India.
Green isn't just our colour — every facility is engineered to give back more than it takes.
Closed-loop water systems at every plant ensure no industrial effluent leaves our facilities.
Capturing and reusing rainwater across all four manufacturing sites.
Effluent treatment plants today, expanding solar capacity tomorrow — cutting our carbon footprint year on year.
When it comes to corrosion protection, appearance alone isn't enough. A practical checklist for what to verify before approving a coated lot.
Heat speeds up chemical reaction rates and weakens protective oxide layers — understanding this relationship is key to component design.
