Our Coating Systems: Advanced Zinc-Aluminium Flake Coatings
What Are Zinc-Aluminium Flake Coatings?
All our coatings are advanced Zinc-Aluminium (Zn-Al) flake systems designed to deliver long-lasting corrosion protection while maintaining complete environmental safety. These water-based, non-electrolytic coatings form a dense metallic barrier of zinc and aluminium flakes that shield metal components from rust, heat, and chemical damage. Unlike conventional plating or painting, Zn-Al flake coatings eliminate the risk of hydrogen embrittlement and offer consistent performance even in extreme industrial environments. Their chromium-free, eco-friendly chemistry ensures compliance with global standards like ROHS and REACH — making them the preferred choice for industries seeking sustainable, high-performance surface protection.
Beyond protection, these coatings redefine the way industries think about surface performance. Their thin, uniform layers ensure precise fitment and torque control for fasteners, while offering exceptional resistance to salt spray, humidity, and high temperatures. With Pristine’s advanced Zn-Al flake coating systems, components don’t just resist corrosion — they retain their integrity, efficiency, and appearance for years to come.
Overview:
GEOCOTE™ S-570 stands as the flagship among Pristine’s zinc–aluminium flake coatings, offering unmatched corrosion protection through advanced material science. Developed for industries that demand both high endurance and environmental responsibility, this water-based, non-electrolytic system forms a tightly bonded metallic barrier that shields metal surfaces from rust, abrasion, and chemical exposure. Its unique flake structure creates overlapping layers of zinc and aluminium, ensuring complete surface coverage and long-lasting protection even under extreme conditions. GEOCOTE™ S-570 delivers exceptional adhesion and a smooth silver finish that reflects precision and reliability — qualities that make it the preferred coating for automotive fasteners, marine parts, and high-performance machinery. Designed for strength and sustainability, it redefines how durability should look and perform in modern engineering.

-
Maintains black appearance even when scratched
-
Zero hydrogen embrittlement risk
-
Designed for black topcoat compatibility
Overview:
GEOCOTE™ BLACK is a high-performance matte black topcoat created to enhance and extend the life of zinc–aluminium base coatings like GEOCOTE™ S-570 and S-BOS. More than just a finishing layer, BLACK MW reinforces the coating system with added resistance to corrosion, chemicals, and temperature fluctuations. Its dense, smooth texture provides a rich, uniform black appearance that complements both aesthetic and functional needs. By forming a seamless, protective film over the base coating, it ensures long-term durability while maintaining consistent friction control for precision assemblies. GEOCOTE™ BLACK reflects the essence of Pristine’s innovation — a sophisticated fusion of strength, style, and sustainability that elevates surface protection to a higher standard.
