What Are Glass Flakes?
Glass flakes are C-glass platelets with a thickness of 5 microns, produced by melting glass marbles at 1200°C, followed by a series of blowing, cooling, crushing, filtering, and milling processes.
Glass flakes are primarily used as lining materials in anti-corrosive coatings applied to metal and concrete surfaces. Additionally, they are widely utilized in pigments, cosmetics, and specialized industrial applications.

How Do Glass Flakes Work?
Glass flakes form dense, inert barriers within a coating film. Their overlapping layers provide exceptional resistance to water and chemical permeation. Furthermore, incorporating glass flakes enhances flexibility, hardness, and abrasion resistance in coatings.
Key Advantages
✔ Tough, flexible, and abrasion-resistant coatings
✔ Proven performance in offshore, subsea, chemical tanks, and process vessels
✔ Long-term durability—coatings can last up to 25 years before major maintenance
✔ Superior chemical resistance across a wide range of applications
✔ Customizable specifications tailored to customer requirements
✔ Extensively used in FGD (Flue Gas Desulfurization), coatings, and pigments
Glass Flake Applications
Anti-Corrosive Coating
Glass flake coatings are industrial paints reinforced with microns-thick glass flakes, significantly enhancing toughness and durability. The two primary types of glass flake coatings are:
- Epoxy-based coatings
- Vinyl ester-based coatings
Benefits:
✔ High chemical resistance to a variety of aggressive substances
✔ Long service life—up to 25 years before first major maintenance
✔ Proven performance in offshore structures, subsea environments, chemical storage tanks, and industrial vessels
Glass Flake Mortar
Glass flake mortar is a specially formulated flake compound made from vinyl ester and epoxy resins, combined with chemically inert glass flakes. It is widely used in:
- Power generation plants
- Garbage incineration plants
- Wastewater treatment facilities
Key Features:
✔ Excellent bonding strength to metal and concrete
✔ Easy application using spray and roller techniques
✔ Outstanding resistance to chemicals, heat, and solvents
Essential Glass Flake Products for Mortar:
C-12V, C-12E, C-28V, and C-28E
Pigment Applications
Glass flakes are essential in pearlescent pigments, offering a unique soft pearl luster that cannot be replicated by other materials. Their special surface structure, high refractive index, and superior transparency create a brilliant, pearl-like effect in transparent mediums.
Ideal Glass Flakes for Pigments:
C-12N, C-28N, and C-150N
