바람직하게는 건설 산업을 위해 증기 투과성이고 그 실리콘계 공기 및 물 배리어는 ≥15개월의 저장 수명을 갖는 액체, 실리콘계 공기 및 물 배리어로서 사용하기 위한 액체 적용된 공기 및 물 배리어 코팅 조성물. 조성물은 (i) (c) 계면활성제 및 (d) 물을 추가로 포함하는 가교된 폴리실록산 분산액; (ii) 조성물의 0.25 내지 5 중량% 양의 하나 이상의 레올로지 개질제, (iii) 조성물의 15 내지 30 중량% 양의 산성 pH 안정한 콜로이드 실리카; 및 선택적으로 (iv) 하나 이상의 안정화제를 포함한다. A liquid applied, silicone-based air and water barrier coating composition and its use as a silicone-based air and water barrier is provided. The barrier is generally vapour permeable and suitable for the construction industry. The liquid coating composition generally has a shelf-life of at least 15 months. The liquid coating composition comprises: (i) a crosslinked polysiloxane dispersion comprising (c) a surfactant and (d) water; (ii) one or more rheology modifiers in an amount of from 0.25 to 5 wt. % of the composition; and (iii) an acidic pH stable colloidal silica in an amount of from 15 to 30 wt. % of the composition; and optionally (iv) one or more stabilizers.
