What is Dacro Coating and how does it work?
Dacro coating (also known as Dacromet) is a premium, water-based zinc-aluminum flake coating used to protect metals (primarily steel and iron) from severe corrosion. It provides up to 10 times the rust protection of traditional electroplating and prevents hydrogen embrittlement in high-strength fasteners.
How it Works
Dacro coating relies on three main defense mechanisms:
- Barrier Protection – Extremely fine flakes of zinc and aluminum align parallel to the metal surface, forming a dense, overlapping physical barrier that blocks air and moisture.
- Cathodic Protection – Zinc acts as a "sacrificial anode." If the coating is scratched and the underlying steel is exposed, the zinc will corrode first, actively protecting the metal underneath.
- Self-Healing Effect – When exposed to moisture, the chromium compounds in the coating form an oxide film that migrates to cover minor scratches, preventing further rust.
Features of Dacro Coating
As providers of Dacro Coating services in India, our solutions offer high precision, durability, and consistent performance.
- Chromium-Free Composition The coating avoids hexavalent chromium entirely, making it a safer choice for workers and end users alike.
- Thin, Uniform Layering It applies in a controlled, thin film that maintains the precise dimensions of threaded and machined components.
- Water-Based System Being water-based rather than solvent-based, it supports cleaner application processes with reduced emissions.
- Reliable Adhesion The coating bonds strongly to metal surfaces, resisting chipping or peeling during handling and assembly.
- No Hydrogen Embrittlement Since it skips electrolytic deposition, it removes the risk of hydrogen-induced weakening in high-strength steel.
- Stable Friction Performance It helps maintain consistent torque-tension values, which is essential for dependable fastening applications.
- Adaptable Topcoat Options The coating pairs well with different topcoats to add colour, lubricity, or additional sealing where needed.
Benefits of Dacro Coating
As well-known Dacro Coating Service Providers in India, here are some of the key benefits of our services:

- Better Cost Efficiency Over Time Enhanced durability and fewer failures add real value across high-volume manufacturing operations.
Applications of Dacro Coating
As Providers of high-precision Dacro Coating Services in India are suitable for multiple industrial applications as listed below:
- Automotive Fasteners: Applied to bolts and nuts exposed to road salt, moisture, and fluctuating temperatures. This keeps them functioning reliably throughout the vehicle's service life.
- Engine Bolts and Components: Used on fasteners located near heat-generating engine parts that also require corrosion resistance. It ensures dependable performance despite ongoing thermal exposure.
- Suspension and Steering Parts: Protects hardware exposed to continuous vibration, road debris, and changing weather conditions. This helps reduce the risk of premature loosening or failure.
- Chassis and Frame Components:Applied to structural vehicle parts that endure constant mechanical stress. It supports long-term durability against fatigue and corrosion.
- Railway Fittings: Used on fasteners exposed to outdoor elements across extensive rail infrastructure networks. This ensures dependable performance over many years of service.
- Construction Hardware: Applied to structural bolts used in buildings and civil infrastructure projects. It helps maintain load-bearing strength despite ongoing weather exposure.
- Agricultural Machinery Fasteners: Protects hardware exposed to soil, fertilizers, and consistent moisture in farming environments. This extends equipment life even under demanding field conditions.
- Wind Turbine Hardware: Used on fasteners that operate in remote, high-exposure outdoor settings. It supports reliable performance with minimal need for maintenance.
- Marine and Offshore Equipment: Suitable for hardware exposed to saltwater, where corrosion risk runs especially high. The coating provides strong resistance against ongoing saline exposure.
- Heavy Industrial Machinery: Applied on fasteners within machinery operating under continuous, high mechanical load. This helps reduce downtime caused by corrosion-related failures.
- OEM Manufacturing Parts: Used across original equipment manufacturing where strict quality and consistency standards must be met. It supports compliance with demanding OEM specifications.
- High-Tensile Structural Bolts: Applied on bolts requiring both mechanical strength and long-term corrosion resistance. This makes it well suited for critical load-bearing applications.
