KM-005100% PFAS-free
Low Refractive Index
Ultra-low refractive index coating reaching RI as low as 1.16 — the lowest available from any PFAS-free supplier globally. Overcoatable for multi-layer AR stacks. Proven to survive furnace tempering at 630°C and deliver 2.5–4.5× light guiding luminance improvement on glass substrates.
