Abstract
Weather-resistant coatings were prepared by mixing a synthesized mill-base and let-down silicone/acrylic resin in weight ratios of 4 : 6, 3 : 7, and 2 : 8. The weatherability of the prepared coatings was tested. The thermal stability, general physical properties, and weatherability of the films of the coatings were improved with silicone content. Among the three mixing ratios mentioned, the ratio of 2 : 8 was the most suitable for the preparation of weather-resistant coatings. The coatings containing 30 wt% of silicone proved to be a high weather-resistant coating.

전보에서 합성된 안료분산용 및 희석용 실리콘/아크릴수지의 배합비를 중량비율 4 : 6, 3 : 7 및 2 : 8 로 다양화하여 내후성 도료를 제조하였다. 제조된 내후성 도료로써 내후성에 속하는 각종 도막물성 시험을 행한 결과 실리콘 성분함량이 증가할수록 열적 안정성, 도막의 일반물성 및 내후성 등이 전반적으로 향상되는 결과를 보여주었으며, 3종류의 수지 배합비 중 2 : 8 의 배합비가 적정선임을 알았다. 또한 실리콘 성분 30 wt% 함유한 도료는 고내후성 도료로서 거동함이 밝혀졌다.

Keywords: weather-resistant coatings; silicone/acrylic resin; weatherability; mixing ratio
