CHROMATING PROCESS: Superior Corrosion Resistance & Surface Preparation.
At Tridok Nig. ltd, we pride ourselves on delivering cutting-edge surface pre-treatment solutions that enhance the durability, appearance, and performance of metal surfaces. Among our specialized services include our chromating process — available in both liquid and powdered forms — stands out as a highly effective treatment for aluminium, zinc, and their alloys.
Whether you’re in aerospace, automotive, construction, marine, or general manufacturing, our chromating services are tailored to meet the most demanding industrial standards, ensuring your components are corrosion-resistant, paint-ready, and environmentally compliant.
WHAT IS CHROMATING?
Chromating, also known as chromate conversion coating, is a chemical process that applies a protective, passive layer of chromium compounds to the surface of non-ferrous metals such as aluminium, zinc, cadmium, and magnesium.
THIS LAYER PROVIDES:
✅ Enhanced corrosion resistance
✅ Excellent adhesion base for paints, powders, and sealants
✅ Conductivity where required (for electrical/electronic applications)
✅ Environmentally safer alternatives (hexavalent-free options available)
At Tridok nig. Ltd we offer both liquid chromating systems and powdered chromating chemicals, allowing us to adapt to your operational needs and environmental goals.
- LIQUID CHROMATING
Our liquid chromating solutions are ideal for industries that demand consistent, high-quality finishes and can accommodate process tanks and controlled baths.
Key benefits of our liquid chromating process:
-Uniform coating thickness for precise engineering tolerances
-Superior corrosion resistance (meets or exceeds MIL and ASTM standards)
-Available in both hexavalent and trivalent (RoHS-compliant) formulations
-Ideal for bulk production and continuous line applications
-Excellent paint adhesion and long-lasting protection
We supply and apply premium-grade liquid chromating chemicals, and our experts ensure that every step of the process adheres to strict quality and environmental standards.
- POWDERED CHROMATING
For operations that prioritize convenience, shelf stability, and flexibility, our powdered chromating solutions are an excellent choice.
Powdered chromating offers:
-Easy storage and longer shelf life
-Simple mixing and preparation on-site
-Cost-effective for smaller batches or irregular production schedules
-Consistent results when properly applied
-Environmentally friendly, with options for hexavalent-free and low-VOC formulations
Our powdered chromating chemicals are formulated to deliver reliable protection and adhesion performance, matching the standards of liquid-based systems while reducing waste and operational complexity.
