The Ultimate Guide to Industrial Tank Coatings

Industrial tanks are the backbone of critical operations in steel, chemical manufacturing, power generation, pulp & paper, and more. But these assets face constant threats—from aggressive chemicals and high temperatures to abrasion and corrosion. The right tank coating isn’t just a layer of protection; it’s the difference between costly downtime and years of reliable, safe performance.

Why Industrial Tank Coatings Matter

Tank failures can mean lost production, environmental hazards, and even regulatory shutdowns. Proactive coating selection and maintenance help facilities:

• Prevent leaks and contamination
• Extend asset life
• Maintain regulatory compliance
• Minimize emergency repairs and costly outages

For 24/7 operations, scheduled outages, or sites handling hazardous chemicals, the right tank coating is your first line of defense.

Types of Industrial Tank Coatings

1. Epoxy and Epoxy-Modified Coatings

Epoxy systems provide exceptional chemical and abrasion resistance, making them a popular choice for water, wastewater, and chemical storage. They bond tightly to steel and concrete, creating a durable barrier against moisture and aggressive agents.

2. Plural Component Coatings

Designed for fast cure and high-build applications, plural component coatings withstand severe industrial abuse. These systems are ideal for tank linings, secondary containment, and areas exposed to heavy loading or frequent cleaning.

3. NSF 61-Certified Coatings

For tanks storing potable water or food-grade products, NSF 61-certified coatings are essential. These coatings guarantee compliance with health and safety standards, protecting both your operation and end users.

4. Containment Coatings

Aggressive chemicals, acids, and solvents demand specialized containment coatings. Engineered for secondary containment areas and tank pads, these linings resist chemical attack, prevent leaks, and minimize environmental risks.

5. Abrasion and Impact Resistant Coatings

Tanks that endure heavy mechanical wear—such as those in mining, steel, or pulp & paper—benefit from abrasion- and impact-resistant coatings. These systems provide a tough, long-lasting shield that reduces maintenance and extends service intervals.

6. Trowel-Applied Linings

For repair, relining, or high-build protection, trowel-applied systems offer seamless, thick coverage. These are particularly effective for restoring aging tanks or containment structures without full replacement.

Choosing the Right Tank Coating: Key Considerations

• Stored Material: What chemicals, temperatures, or abrasives will the coating face?
• Tank Material: Steel, concrete, fiberglass, and others require different surface prep and coating systems.
• Compliance Requirements: NSF 61, EPA, or industry-specific standards may dictate your options.
• Downtime Tolerance: Many RAK solutions are engineered for rapid cure and minimal disruption, ideal for plants that run 24/7.

Best Practices for Tank Coating Maintenance

1. Regular Inspections: Identify early signs of coating failure—blistering, discoloration, or pinholes.
2. Prompt Touch-Ups: Minor defects can be addressed before they become leaks.
3. Professional Application: Trust experts like RAK for surface prep, specification, and application—reducing the risk of early failure.
4. Documentation: Maintain records for compliance audits and future maintenance planning.

Conclusion

Industrial tank coatings aren’t just a finish—they’re critical to plant performance, safety, and business continuity. The right coating, applied and maintained by experts, allows you to focus on production—not on preventable repairs and emergencies.
