Intermediate & barrier coats provide additional protection against penetration of corrosive media through multilayer paint systems.
The coatings containing MICA platelet shaped particles can reduce water and oxigen permeability rates as much as five-fold when they are aligned parallel to the coating surface. Thus, water vapours and oxygen cannot pass through the pigment particles, the presence of aligned platelets can reduce the rate of vapour permeation through the coating. Prospectrum Coatings BVBA has a comprehensive range of polyurethane and epoxy coatings and mastics with mica, micaceous iron oxide and glass flakes.
