Fiber Reinforced Intumescent Grout


Glass flakes have been utilized in a diverse range of applications bringing improvement in reinforcement, barrier and thermal properties.

The primary application glass flakes found was as a filler to improve both barrier properties and reinforcement in anti-corrosive coatings in the early 1970’s. Since then the use of glass flake filled materials in coating systems has grown significantly, as their inherent benefits have become more widely known. Nowadays, glass flake based coatings are recognised to give superior protection in a variety of industry sectors such as: marine, oil & gas, mining, power generation, chemical plants and storage facilities, paper pulp mills and many other areas.

Advantages of using Fiber Reinforced Intumescent Grout

Reduction of moisture vapour transmission

Although all polymers will convey moisture through them, the process can be slowed down by incorporating Fiber Reinforced Intumescent Grout. This is due to the morphology of the Fiber Reinforced Intumescent Grout which is a high aspect ratio lamellar platelet. The ability of these platelets to align planar to one another and the substrate, when applied in a coating system, gives rise to an in-situ barrier creating a tortuous path through the coating. Even aligned flakes though do not present a continuous barrier but they do significantly extend the permeation path length compared to either an unfilled coating or those that contain granular or fibre fillers.


Fiber Reinforced Intumescent Grout improve mechanical properties, giving isotropic reinforcement across the plane of the platelet.

Improved tribological properties

Fiber Reinforced Intumescent Grout filled coatings are widely used for applications such as high traffic floor coatings. Such applications require significantly improved wear and abrasion resistance of a coating system that can be achieved by the addition of Fiber Reinforced Intumescent Grout. This is due to the nature of the glass which in general has a Mohs hardness and the ability of flakes to align in a parallel manner within the coating.


Fiber Reinforced Intumescent Grout offers a wide range of products for use in coating systems. The formulation of a coating is not simply a case of adding an arbitrary amount of flake to a resin and expecting to have an ideal coating system. Consideration should be given to the flake thickness, particle size diameter, type of glass composition and whether a surface treatment is required to impart the properties required for a particular coating system.
