Glass Flake Coatings

Glass flake coatings are specialised protective coatings that consist of micron-sized glass flakes embedded in a binder or resin system.

These coatings are designed to provide superior corrosion, abrasion, and chemical resistance, making them suitable for various applications in industries such as marine, offshore, petrochemical, and water treatment.

Technical Details

Glass flakes

The glass flakes used in these coatings are typically made from high-quality, chemically-resistant borosilicate or E-glass materials. The flakes are thin, flat, and transparent, with thicknesses ranging from 5 to 50 microns and an average size of 200-500 microns.

Binder/Resin system

The binder or resin system serves as the matrix that holds the glass flakes in place, providing the coating's mechanical strength, adhesion, and flexibility. Common binder systems include epoxy, vinyl ester, polyester, and polyurethane resins.

Surface preparation

Proper surface preparation is essential to ensure good adhesion and performance of the glass flake coating. The surface should be clean, dry, and free of any contaminants, such as oil, grease, or rust. Abrasive blasting is often employed to create an appropriate surface profile for optimal adhesion.

Cure time

After application, the coating requires a specific cure time to achieve its final properties. This time depends on the type of binder used and can range from a few hours to several days. Some coatings may also require heat or UV curing to achieve their final properties.

Surface Preparation, Metal Preparation & Structural Surface Preparation

Global coatings are able to provide a range of blast media to suit the majority of industry surfaces and preparation requirements from corrosion removal, cleaning and preparation for the addition of various paint systems.

Grit Blasting Services by Global Coatings

Grit blasting, also known as abrasive blasting or sandblasting, is a surface preparation technique that involves propelling abrasive particles, commonly referred to as grit, at high velocities against a surface. This process removes contaminants, such as rust, paint, and scale, while creating a uniform profile for improved adhesion of coatings and treatments.

Blast Cleaning

Global Coatings specialise in blast cleaning, as an effective and versatile surface treatment method used across various industries to prepare surfaces for cleaning and finishing.
