Note: The data above apply to representative grade 28C10. Optical properties were measured using a Glass/OCA/Glass structure at room temperature. Refractive index was measured at 23°C and 589 nm (JIS K 7142). The 180° peel test speed was 300 mm/min, with peel strength expressed in N/25 mm. Refer to the latest technical data for actual specifications and applicable conditions.
