FleXFOLD

FleXFOLD

Flexible hard coat for PET and CPI films

FleXFOLD forms highly transparent, optically clear and flexible hard-coating, which is scratch and chemical resistant, easy to clean and has excellent optical properties.

Best-in-Class optics, scratch resistance and foldability

FleXFOLD is a siloxane polymer based coating designed for flexible PET plastic films. FleXFOLD forms highly transparent, optically clear and flexible hard-coating, which is scratch and chemical resistant, easy to clean and has excellent optical properties. FleXFOLD is capable of withstanding dynamic folding with below one-millimeter radius and as such is ideal for foldable display and touch screen applications. Compatible with standard AF treatments.

Main Applications

• Protective overlays
• Bendable Screens
• Lighting Fixtures / Luminaires

Key features

• Truly flexible coating
• Scratch Resistant Hard-Coat
• Easy-to-Clean
• Chemically Resistant
• Cost savings through improved energy efficiency
• Reduced surface reflection

Technical Background

Plastics are everywhere due to their light weight and design flexibility. However, most of the commonly used plastics are easily scratched, susceptible to degradation by various chemicals and suffer mechanical stress when folded to a small bending radius. Optitune’s robust hard coats help circumvent these issues while delivering excellent optical properties.

How to Apply

The solution is applied as a single-layer coating using a roll-to- roll (R2R) or sheet coating process followed by thermal and UV curing steps. Coating can be carried out using slot/die, gravure, reverse gravure, Meyer bar or other method. Plasma or corona pre-treatment may be necessary depending on substrate manufacturer grade. After final curing, a stabile coating performance is achieved.
