Polyvinylidene Fluoride Coatings (PVDF)
? ? PVDF ( polyvinylidene fluoride ) is a chemical resistant thick film barrier coating commonly used in architectural applications where both excellent appearance and substrate protection must be maintained over a long period of time. This coating is unaffected by most chemicals and solvents and has excellent wear and abrasion resistance. PVDF also has a high dielectric strength, excellent resistance to weathering and the ability to self extinguish.
Polyester Coatings (PE)
? ? PE ( polyester ) coatings exhibit an excellent combination of hardness, flexibility, flow, appearance, and superior resistance to dirt retention in indoor and outdoor applications. These coatings are highly resistant to abrasion, metal marking, staining, and marring, and require minimal maintenance. Glazetech uses polyester paints which provide excellent colour and gloss retention properties.
