It is important to secure numerical accuracy while ensuring adhesion with high transparency and low yellowing properties to protect against physical impacts outside the drone. In addition, in order to derive high-quality results for preventing damage and discoloration from ultraviolet rays and atmospheric chemicals, a release layer process technology in which a silicone-based release is coated at a certain thickness and then cured at an appropriate temperature and time, and a technology for optimizing adhesion of adhesive thickness and solid content during adhesive coating were confirmed, and the protective film confirmed the results of surface suitability, retention, and stability evaluation over time for drone aircraft and external parts over a long period of time.
