Chlorinated Rubber Paint vs Crown Anti-Corrosion Paints: Which is Best for Metal Protection?

Protecting metal surfaces from rust and corrosion is crucial, whether you’re handling industrial equipment, water tanks, gates, or DIY projects. Two of the most common paint systems in Kenya are Chlorinated Rubber (CR) Paints and Crown Anti-Corrosion Paints (Zinc Phosphate Primer, Grey Primer, and Aluminium Paint). But which one is the best for your project?

At Rangi Paint Store, we stock all these paints, giving you the choice to protect your metal surfaces efficiently and cost-effectively.

What Are Chlorinated Rubber Paints?

Chlorinated Rubber paints are solvent-based coatings designed for durability and chemical resistance. They are widely used in harsh environments, including marine, industrial, and outdoor applications.

Key Features of Chlorinated Rubber Paints:

Excellent chemical resistance: Protects against acids, alkalis, and salts.
Waterproof and durable: Ideal for coastal or marine structures.
Quick drying: Saves time on large projects.
Glossy finish: Provides a smooth and shiny appearance.
Versatile adhesion: Works on metal and concrete with proper preparation.

Common Uses: Water tanks, industrial machinery, steel gates, marine structures, and pipelines.

Limitations:

Strong solvent smell → needs ventilation.
Limited UV resistance → can fade in direct sunlight.
Requires meticulous surface preparation to prevent peeling.

What Are Crown Anti-Corrosion Paints?

Crown Anti-Corrosion Paints are a trusted solution for long-term rust prevention. This system includes Zinc Phosphate Primer, Grey Primer, and Aluminium Paint. They are especially popular in Kenya for both industrial and DIY metal protection projects.

Key Features:

Zinc Phosphate Primer: Creates a chemical bond with metal, forming a strong corrosion-resistant layer.
Grey Primer: Affordable, moderate rust protection for light-duty projects.
Aluminium Paint: Reflective metallic finish that protects against UV, water, and rust.
Durability: Properly applied, these paints can last 5–7 years outdoors.
Low VOC options: Safer for indoor and semi-enclosed applications.

Common Uses: Gates, roofing sheets, water tanks, grills, industrial machinery, and pipelines.

Chlorinated Rubber vs Crown Anti-Corrosion Paints: Head-to-Head Comparison

Feature	Chlorinated Rubber Paint	Crown Anti-Corrosion Paints
Rust Protection	Moderate, works best with primed surfaces	High, especially with Zinc Phosphate Primer
Durability	Good, chemical-resistant but UV can fade	Excellent, long-term corrosion resistance
Finish	Glossy	Metallic (Aluminium Paint) or matte (Primer)
Drying Time	Fast	Moderate (depends on primer and coat thickness)
Cost	Medium	Medium–High (depending on primer + aluminium paint combination)
Ease of Application	Solvent-based, requires ventilation	Water-based or low VOC, easier and safer
Best For	Chemical exposure, marine structures	General rust prevention, industrial & DIY projects

Verdict:

Use Chlorinated Rubber Paint if chemical resistance or marine exposure is your priority.
Use Crown Anti-Corrosion Paints for long-term rust protection and metal durability in general industrial, outdoor, and DIY projects.

How to Get the Best Results

Step 1: Surface Preparation

Remove rust, dust, oil, and grease.
Use wire brushing, sanding, or degreasing solutions.

Step 2: Primer (If Using Crown Paints)

Apply Zinc Phosphate Primer for heavy-duty protection.
Apply Grey Primer for light-duty surfaces.

Step 3: Topcoat

For Crown: Apply 2–3 coats of Aluminium Paint for maximum durability.

FAQ

Which is better for rust protection, Chlorinated Rubber paint or aluminium paint?

Aluminium paint over Zinc Phosphate Primer (Crown system) provides superior long-term rust protection, while Chlorinated Rubber paint is better for chemical resistance.

Can I apply Chlorinated Rubber paint over Aluminium paint?

No, it’s best to apply Chlorinated Rubber paint over a clean, primed surface. Aluminium paint should generally be used as the topcoat in Crown systems.

How long does Chlorinated Rubber paint last outdoors?

Typically 3–5 years, depending on exposure to weather and chemical environments.
