How Glass Flake Coatings Protect Industrial Tanks from Corrosion

Industrial tanks are regularly exposed to chemicals, moisture, temperature changes and demanding operating conditions. Over time, these conditions can cause corrosion and surface deterioration, particularly when the tank material is exposed to aggressive environments.

Glass flake coatings provide a protective barrier designed for demanding industrial applications. Chemiprotect’s glass flake products are developed as part of its range of corrosion-resistant solutions for industrial facilities. The company also provides glass flake and glass matt reinforced coating, flooring and tank lining services, designed for applications involving chemical and temperature exposure.

Understanding how glass flake coatings protect industrial tanks from corrosion starts with understanding how the coating structure works and why it is suitable for demanding environments.

Why Do Industrial Tanks Need Corrosion Protection?

Industrial tanks may store or process chemicals and other substances that can attack exposed surfaces. Continuous exposure can gradually affect steel, concrete and other substrates if they are not adequately protected.

Corrosion can lead to surface deterioration, maintenance requirements and reduced service performance. For this reason, industrial facilities use protective coating and lining systems to create a barrier between the substrate and the surrounding environment.

The right coating depends on the tank material, chemical exposure, operating conditions, temperature and application requirements.

What Is a Glass Flake Coating?

A glass flake coating is a resin-based protective coating reinforced with properly graded glass flakes. Chemiprotect’s MIPROGLASS 101 documentation describes these coatings as polyester, vinyl ester or epoxy resin-based systems designed to protect steel and concrete against atmospheric corrosion and tank or process-plant exposure to chemical splashing and spillage.

The glass flakes are incorporated into the coating and positioned parallel to the substrate. This structure contributes to resistance against permeation, corrosion, abrasion, physical abuse and thermal shock.

Different resin systems can be selected depending on the required application and chemical resistance.

How Do Glass Flakes Help Prevent Corrosion?

The structure of the coating plays an important role in its protective performance. Instead of relying only on the resin layer, the glass flakes create a reinforced barrier within the coating.

Creates a Barrier Against Permeation

Glass flakes positioned within the coating help make it more difficult for liquids and aggressive substances to permeate through the protective layer. This supports the coating’s role as a barrier between the environment and the underlying substrate.

Supports Corrosion Resistance

By reducing direct exposure of the substrate to corrosive conditions, the coating can help protect steel and concrete surfaces from corrosion-related deterioration.

Improves Resistance to Abrasion

Industrial tanks and process areas can experience physical wear in addition to chemical exposure. Glass flake reinforced coatings are designed to provide resistance to abrasion and physical abuse.

Why Are Glass Flake Coatings Suitable for Tank Applications?

Tank environments can involve chemical splashing, spills, immersion and demanding operating conditions. A protective coating therefore needs to provide more than basic surface coverage.

Chemiprotect’s MIPROGLASS 101 series is designed for steel and concrete applications, including exterior tank surfaces and process-plant areas exposed to chemical splashing and spillage. The documentation also states that selected MIPROGLASS 101 series coatings can withstand gas temperatures up to 120°C and can be used for immersion service at ambient temperatures.

The specific grade should be selected according to the actual service conditions and required chemical resistance.

Glass Flake Coatings for Different Industrial Conditions

Not every tank operates under the same conditions. Chemical concentration, temperature, immersion, abrasion and substrate type can vary considerably from one facility to another.

Chemical Exposure

Tanks and process areas exposed to chemical splashes or spills require a coating system suitable for the specific chemical environment.

Temperature Exposure

Operating temperature can influence coating selection. The appropriate resin system and grade should be selected according to the expected temperature conditions.

Abrasion and Physical Wear

Where equipment, materials or industrial activity may cause physical wear, abrasion resistance becomes another important consideration when selecting a protective coating.

A coating should therefore be selected based on actual operating conditions rather than using the same system for every application.

What Resin Systems Are Available?

The MIPROGLASS 101 range includes different resin-based formulations. According to Chemiprotect’s product documentation, the series includes isophthalic polyester, bisphenol polyester, vinyl ester, superior-grade vinyl ester and epoxy options.

Polyester-Based Systems

Polyester-based options can be considered for applications requiring suitable corrosion protection based on the specific operating environment.

Vinyl Ester Systems

Vinyl ester formulations provide another option for demanding chemical-resistant applications, subject to the required chemical resistance.

Epoxy Systems

Epoxy-based formulations can be selected for applications where an epoxy resin system is appropriate.

The correct grade should always be determined according to the chemical resistance requirements and service conditions of the tank.

How Is a Glass Flake Coating Applied?

Proper application is an important part of achieving reliable coating performance. Chemiprotect’s MIPROGLASS 101 documentation states that the coatings can be applied by brush or spray and cure at ambient temperature. The recommended thickness is approximately 400–500 microns, achieved through a primer and multiple coating layers depending on the application environment.

Surface Preparation

The substrate needs to be appropriately prepared before coating application. Surface condition, cleanliness, roughness and other factors can influence adhesion and final performance.

Primer Application

A suitable primer can be used as part of the coating system before applying the glass flake layers.

Multiple Coating Layers

The required number of coats depends on the application environment and target thickness. Following the specified application system helps achieve the intended protective barrier.

Benefits of Glass Flake Coatings for Industrial Tanks

Glass flake coatings can provide several advantages when correctly selected and applied for suitable industrial conditions.

Key benefits include:

Resistance to corrosion

Reduced permeation

Resistance to abrasion

Resistance to physical abuse

Resistance to thermal shock

Protection against chemical splashing and spillage

Suitability for steel and concrete substrates

Multiple resin options for different applications

These characteristics make glass flake reinforced systems useful for demanding industrial surface protection applications.

Where Can Glass Flake Coatings Be Used?

Glass flake systems can be considered for industrial environments where corrosion and chemical exposure are concerns.

Typical applications can include tank exteriors, process plants, steel structures and concrete surfaces exposed to corrosive conditions. Chemiprotect also lists glass flake and glass matt reinforced coating, flooring and tank lining among its specialized industrial services.

Industries with chemical handling, processing and other demanding operating environments can evaluate glass flake systems according to their specific requirements.

How to Select the Right Glass Flake Coating

Choosing a coating should begin with the actual operating conditions. Important factors include the substrate, type of chemical exposure, concentration, operating temperature, immersion conditions, abrasion requirements and expected service environment.

Identify the Substrate

Determine whether the coating will be applied to steel, concrete or another suitable substrate.

Understand Chemical Exposure

The chemical type and concentration should be evaluated before selecting the resin system. Chemiprotect recommends referring to the appropriate chemical resistance information for individual MIPROGLASS grades.

Consider Application Conditions

Temperature, immersion, physical wear and application method should all be considered when selecting the appropriate coating system.

Protect Industrial Tanks With the Right Coating System

Glass flake coatings provide a reinforced protective barrier for industrial tanks and process environments where corrosion, chemical exposure, abrasion and permeation can be concerns. The glass flakes within the resin system contribute to the coating’s resistance and help protect the underlying substrate.

However, the effectiveness of any coating system depends on selecting the appropriate formulation, preparing the substrate correctly and applying the coating according to the specified requirements.
