Abstract

In this paper, the influence of ambient temperature and relative air humidity on the hydrophobicity transfer property of HTV and RTV silicone rubber (SR) is investigated. The static contact angle on polluted HTV-SR samples and plates with RTV coating was measured while being stored at different temperature and relative humidity. It has been found that the transfer characteristics on HTV-SR exhibit a saltus between 50°C and 55°C. The results further show that the influence of relative humidity is related with the hygroscopicity of soluble and non-soluble substances in pollutants on the surface.
