Industrial Zinc Flake Coating Services
Embrittlement-Safe Corrosion Protection for High-Strength Fasteners
Fukar provides zinc flake coating services for fasteners and components that require high corrosion resistance with no hydrogen embrittlement risk. Zinc flake systems are widely specified for high-tensile bolts, structural hardware, and severe-service assemblies.
Our coating process is managed under ISO 9001:2015 quality systems with controlled application and curing parameters. Fukar supports quality-controlled industrial coating programs for automotive, construction, and oil and gas supply chains.
Zinc flake systems are often selected where long corrosion life and embrittlement-safe protection are critical for operational reliability and safety.
Performance Highlights
Why Engineers Specify Zinc Flake Coating
1,000+ Hour Corrosion Resistance
Designed for severe-service environments where standard coatings may not meet corrosion life targets.
No Hydrogen Embrittlement
Suitable for high-tensile fasteners where embrittlement risk from electroplating must be avoided.
Thin, High-Performance Coating System
Provides strong corrosion performance with controlled coating build for threaded and precision fastener applications.
Technical Reference
Zinc Flake Coating Specification Snapshot
Zinc flake coating selection depends on fastener grade, corrosion target, topcoat requirement, and service environment. Requirements are confirmed during technical review before production.
Our team can align process output to your drawing notes and quality documentation requirements.
Discuss Your Spec| Parameter | Typical Reference |
|---|---|
| Primary Standard | Zinc-aluminium flake coating systems (project-specific requirements) |
| Common Thickness Range | Typically 8–20 µm base + topcoat system dependent |
| Corrosion Benchmark | 1,000+ hours salt spray (ASTM B117 reference) |
| Hydrogen Embrittlement Risk | None (process does not induce hydrogen embrittlement) |
| Typical Use | High-strength bolts, structural fasteners, anchors, oil & gas bolting systems |
How It Works
Zinc Flake Coating Process Flow
1. Pre-cleaning
Degreasing and cleaning remove oils and contaminants before coating application.
2. Surface Prep
Surface preparation ensures clean substrate profile and adhesion readiness.
3. Zinc Flake Application
Controlled application builds zinc flake system thickness to specification.
4. Thermal Curing
Coated parts are oven-cured to form a durable protective flake matrix.
5. Drying
Parts are dried and handled using controlled finishing procedures.
6. Final QA
Final checks for thickness, appearance, and process compliance records.
Common Questions
Zinc Flake Coating FAQ
Answers to common technical and application questions from engineering and procurement teams.
Ask a Technical QuestionWhat is zinc flake coating used for?
Zinc flake coating is used for high-strength fasteners and structural components requiring high corrosion resistance without embrittlement risk.
How much corrosion resistance can zinc flake coating provide?
Zinc flake systems can achieve 1,000+ hours neutral salt spray resistance under ASTM B117 references, depending on system design.
Why choose zinc flake over electroplating for high-strength bolts?
Zinc flake systems avoid hydrogen embrittlement risk, making them suitable for high-tensile fasteners and critical bolting applications.
Is zinc flake coating suitable for oil and gas fasteners?
Yes. Zinc flake coating is commonly used on oil and gas fasteners due to high corrosion performance and embrittlement-safe protection.
Does Fukar provide zinc flake coating in Shah Alam?
Yes. Fukar provides zinc flake coating services from Shah Alam under ISO 9001:2015 quality systems and controlled process parameters.
