Excellent weather resistance! Achieved a film formation method that minimizes warping even with a single-sided multilayer film coating.
The "Stress-Free Coating" is a multilayer film that brings the warping (stress) of the substrate as close to zero as possible. In typical multilayer films, the film itself generates a pulling force (stress) on the substrate, leading to the phenomenon of warping. Through our unique technology development, we have achieved a film formation method that minimizes warping even with a single-sided multilayer film coating. [Features] - Achieved a film formation method that minimizes warping even with a single-sided multilayer film coating - Excellent weather resistance - Passed UV resistance test (10,000 mJ/cm² exposure) and annealing test (250°C for 2 hours) - Outstanding flatness *For more details, please refer to the PDF document or feel free to contact us.
