Vinyl Ester Glass Flake Coating
High-performance barrier for aggressive chemical and high-temperature environments.
A vinyl ester glass flake coating is a high-performance protective coating that combines a vinyl ester resin matrix with thin, flat glass flakes. It is prized for creating a tough, impermeable, and corrosion-resistant barrier, especially in aggressive chemical and high-temperature environments.

Superior Chemical Resistance
Vinyl ester resins are highly resistant to a broad range of chemicals, including strong acids, alkalis, and solvents. Novolac vinyl ester variations are available for even more aggressive chemical resistance.
Excellent Corrosion Protection
The glass flake reinforcement drastically reduces the coating's permeability, creating an impermeable barrier that prevents corrosion of steel and concrete substrates.
High Thermal Stability
These coatings can withstand significant temperature fluctuations and elevated temperatures without losing their protective properties.
Abrasion And Impact Resistance
The glass flakes add toughness and hardness to the resin, allowing the coating to withstand physical abuse, abrasion, and erosion.
Adhesion And Flexibility
The coating offers excellent adhesion to properly prepared steel and concrete surfaces and is more flexible and impact-resistant than polyester-based coatings.
Higher Resistance
Offers a higher degree of chemical and thermal resistance than standard epoxy or polyester coatings.
Vinyl Ester glass flake primer - 1x 150 mic + Vinyl solvent free glass flake epoxy - 1x 400 mic.
Common Applications / Use
Due to their robust nature, vinyl ester glass flake coatings are used in demanding industrial settings.
Oil And Gas Industry
Used for internal and external coating of pipelines, storage tanks, and offshore platforms exposed to saltwater and corrosive chemicals.
Chemical Processing Plants
Protects reactors, vessels, and other equipment from corrosive acids, alkalis, and solvents.
Power Generation
Applied to flue gas desulfurization (FGD) systems, scrubbers, ducts, and chimney linings to protect against highly corrosive and high-temperature flue gases.
Marine Industry
Protects ship hulls, ballast tanks, and other submerged and offshore structures from corrosion in harsh marine environments.
Water And Wastewater Treatment
Provides corrosion protection for tanks, pipes, and other infrastructure.
