Technology evolution
From single-function to integrated material systems
Single-function
One layer, one job: hardcoat, anti-static, or AR.
Multi-functional
Multiple functions per layer: AS + AF + HC in one step.
Integrated systems
Complete optical architectures from a unified PFAS-free platform.
Validated at scale
“500,000 kg antistatic hardcoat supplied over 4 years to a major display OEM”
“ULR haze 0.41% vs incumbent 0.68% (3-layer Japanese supplier) — lower haze, higher hardness, zero curl”
“ATO haze 0.2–0.3% validated by Tier-1 PVB interlayer partner for automotive”
“200,000 fold cycles passed — 20x durability vs sputtered AR hardcoats”
