Metal Coating/Plating
Phosphate
Phosphate coating is a chemical treatment applied to seal casings, forming a protective layer that enhances corrosion resistance and improves surface adhesion for lubricants and seals. This coating provides a robust foundation for PTFE rotary lip seals, ensuring reliable performance in demanding environments, such as industrial machinery and automotive applications, by reducing wear and extending service life.
Zinc Dichromate
Zinc dichromate coating offers superior corrosion protection for seal casings, creating a durable, sacrificial barrier that shields against rust and environmental degradation. Ideal for harsh operating conditions, this coating ensures long-lasting performance and compatibility with PTFE rotary lip seals, making it a trusted choice for applications in marine, automotive, and heavy-duty industrial systems.
Anodize
Anodizing is an electrochemical process that forms a tough, corrosion-resistant oxide layer on seal casings, typically aluminum. This enhances the casing’s durability, wear resistance, and aesthetic finish while maintaining precise tolerances for PTFE rotary lip seal integration. Anodized casings are well-suited for high-performance applications in aerospace, automotive, and precision machinery, offering excellent protection in corrosive or high-temperature environments.
