What is an Epoxy Intermediate Protective Coating?
An epoxy intermediate coating is the middle layer in a multi-coat protective system applied between the primer coat and topcoat.
This layer primarily provides:
• Additional coating thickness
• Chemical protection
• Good bond between coating layers
The following are common applications of Epoxy Intermediate Protective Coating:
• Structural steel
• Storage tanks
• Pipelines
• Offshore platforms
• Industrial flooring systems
• Process plants
• Marine structures
• Refineries & Petro chemical works
Understanding Solvent Free Epoxy Coating Technology
What is a Solvent Free Epoxy Coating?
A solvent free epoxy coating has very little or no volatile solvents. These coatings offer high build protection and minimize VOC and environmental impacts.
Advantages of Solvent Free Epoxy Coatings
• High Film Build in Fewer Coats
• Lower VOC Emissions
• Excellent Chemical Resistance
• Improved Durability
• Better Adhesion
Common Causes of Coating Failure in Industrial Projects
If the coating system is poorly designed or are applied incorrectly, the coating could fail prematurely. By understanding the reasons behind coating failure, industries can enhance asset protection and minimize maintenance expenses.
Poor Surface Preparation
If rust, dust, oil, moisture, or old coatings remain on the substrate, the coating may lose adhesion and begin peeling or blistering.
Practical Recommendation
Do proper abrasive blasting, cleaning and surface profiling prior to coating application.
Moisture Entrapment
Coatings applied on moist surfaces can keep moisture inside the film which will cause blisters and delamination.
Practical Recommendation
Make sure that the substrate is dry and that the environmental conditions are within the recommended application range.
Incorrect Coating Thickness
The Coating Thickness is not correct. Too thin will not provide adequate barrier protection, too thick can cause cracking or curing issues
Practical Recommendation
Apply coatings according to the manufacturer's specifications and perform periodic checks.
Incompatible Coating Systems
Incompatible primers, intermediate coats and topcoats can impact adhesion and performance.
Practical Recommendation
Use complete protective coating systems designed for compatibility and performance.
Chemical Exposure Beyond Design Limits
The high-performance epoxy coatings can be weakened by continuous exposure to aggressive chemicals, which are outside the design parameters.
Practical Recommendation
Choose coatings for specific exposure and chemical resistance requirements
Offshore Corrosion Challenges in Marine Environments
Marine and offshore environments are among the most corrosive operating conditions for steel structures.
Common Offshore Corrosion Problems
• Salt spray corrosion
• Pitting corrosion
• Underfilm corrosion
• Coating breakdown
• Erosion due to wave and sediment action
• Cathodic disbondment
Why Epoxy Intermediate Coatings are Critical Offshore
