Abstract

출원인들은 플루오로지방족 중합체로 피복된 엘라스토머 키패드가 스킨 오일에 대한 내성을 증가시킨다는 것을 발견하였다. 특히, 펜타데카플루오로옥틸 메타크릴레이트 중합체 도료의 사용은 스킨 오일에 대한 실리콘 고무 키패드의 내성을 5배 증가시킨다.Applicants have found that elastomeric keypads coated with fluoroaliphatic polymers increase resistance to skin oils. In particular, the use of pentadecafluorooctyl methacrylate polymer paint increases the resistance of the silicone rubber keypad to skin oil by five times.
