High-Performance Functional Coatings by Roll-to-Roll Sputtering Technology

What Are Functional Coatings?

Functional coatings are thin-film layers applied to substrates to provide specific properties such as conductivity, optical performance, barrier protection, or antibacterial functions. Roll-to-Roll Sputtering (RTR sputtering) is the most efficient method for continuous production on flexible films and metal foils. It is widely adopted across industries including electronics, medical devices, energy, and packaging.

Key Features of RTR Sputtering Technology

• Continuous Production: Ideal for large-area and long-length film coating

• High Precision: Nanometer-level thickness and composition control

• Multi-Functional Capability: Enables conductive, optical, barrier, corrosion-resistant, and antibacterial coatings
