Zinc Phosphating & Stainless Passivation
Surface Conditioning for Corrosion Control and Paint Preparation
Fukar provides zinc phosphating and stainless passivation services for components requiring controlled pre-treatment, corrosion control, and process stability. We support material-specific treatment routes based on component type and downstream requirements.
Our process is managed under ISO 9001:2015 quality systems with controlled cleaning, treatment, and final handling steps. Fukar supports industrial programs across automotive, construction, and general engineering sectors.
Phosphating and passivation are often selected where reliable surface preparation and stable corrosion behaviour are required before painting, assembly, or service.
Performance Highlights
Why Engineers Specify Phosphating & Passivation
Pre-Paint Surface Preparation
Zinc phosphating creates a conversion layer that helps support consistent downstream paint and coating adhesion.
Stainless Surface Restoration
Passivation supports corrosion resistance by removing free iron and restoring protective stainless surface characteristics.
Process Consistency for Production
Controlled treatment steps help maintain repeatable surface quality across production batches.
Technical Reference
Phosphating & Passivation Specification Snapshot
Process selection depends on substrate material, pre-treatment requirement, corrosion target, and downstream finishing process. Requirements are confirmed during technical review before production.
Our team can align process output to your drawing notes and quality documentation requirements.

How It Works
Phosphating & Passivation Process Flow
1. Pre-cleaning
Degreasing and cleaning remove oils and contaminants before treatment.
2. Surface Activation
Surface activation prepares substrates for stable phosphating or passivation treatment.
3. Phosphating & Passivation
Components undergo zinc phosphating or stainless passivation according to process requirement.
4. Rinse & Neutralise
Parts are rinsed and neutralised to remove residues and stabilise surface condition.
5. Drying
Components are dried and handled using controlled process procedures.
6. Final QA
Final checks for thickness, appearance, and process compliance records.
Common Questions
Phosphating & Passivation FAQ
Answers to common technical and application questions from engineering and procurement teams.
Ask a Technical QuestionWhat is zinc phosphating used for?
Zinc phosphating is used as a pre-treatment layer to improve paint adhesion and corrosion performance on steel components.
What is stainless steel passivation used for?
Passivation removes free iron contamination and helps restore corrosion-resistant behaviour on stainless steel surfaces.
Can phosphating improve coating adhesion?
Yes. Zinc phosphating can improve paint and coating adhesion when process parameters are controlled correctly.
Which industries use phosphating and passivation?
These treatments are used in automotive, construction, fabrication, and industrial manufacturing where controlled surface preparation is required.
Does Fukar provide phosphating and passivation services in Shah Alam?
Yes. Fukar provides phosphating and passivation services from Shah Alam under ISO 9001:2015 quality systems and controlled process parameters.
