| 摘要 |
The present invention relates to a composition and a method for treating substrates, in particular hard surfaces, to make the substrate hydrophilic; and for imparting anti-fogging/anti-condensation properties onto said surface. The object of the present invention is to provide a composition for rendering a surface less susceptible for vapour deposition, rendering a surface hydrophilic, making it less susceptible to fogging and frost deposition. It has been found that a composition comprising polyaluminium chloride, a polycarboxylate polymer and a weak acid, when applied to a surface, renders said surface super hydrophilic, thus causing the repellence of small water droplets and anti-fogging effect. |
