Note: The values above are representative data for model 28D10. Optical properties were measured on 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, and peel strength is expressed in N/25 mm. Customer evaluation pass criteria require no whitening, yellowing, delamination, delayed bubbles, abnormal operation, or display MURA after testing. Actual specifications are subject to the latest technical documentation.
