Description

Many composite structures consist of an E-glass chopped strand mat or gun roving in a resinmatrix. These structures are often used to contain fluids internally or exclude fluids externally e.g.tanks, pipework and boat hulls.

The addition of Microglas® Glass Flake products during the manufacture of the component willresult in the glass flakes forming a multi-barrier layer. This ability to form a multi-barrier layer isalso exploited in anti-corrosion coatings.

The principal additional benefits of using Microglas® Glass Flake products to create this layer are:

• Reduced liquid and vapour permeability• Reduced water absorption• Improved wear and damage resistance• Improved dimensional stability
