Flake Lining

Flake Lining is anti-corrosive coating systems for severe exposures.
Flake compound is made from thermosetting liquid resin mixed with glass flakes in microns thick, and applied in a thickness of 0.5~3.0mm.
Glass flakes as barrier fillers make the coating much more durable and prevent permeability of corrosive substances, as the layers of laminated glass flakes (50~100 layers in 1mm thickness) form a highly impermeable structure.
