Abstract
Acrylate based UV protective coating was developed with understanding of rheological properties of polymer fluid. Depending on variables (a rotating speed, ramping time to reach the fixed speed, and crosslinking time), we evaluated physical properties such as film thickness, light blocking rate, and reliability. As a result, thin optical transparent film with UV blocking rate of 68% (total of UV-A and UV-B) and visible light transmittance of more than 95% was developed with acrylate based polymer film excluding urethane oligomers. With increasing rotating speed and ramping time to reach the fixed rotating speed, thickness and the light blocking rate of film was increased. In conclusion, we examined the spin coating process both experimentally and fundamentally with acrylate based UV protective coating. The developed UV protective film showed good optical properties in addition to satisfactory wear and chemical resistances.
