Abstract
The present disclosure relates to a coating composition, in particular a cool roof or solar reflective coating composition, which comprises an organosilane-functionalised colloidal silica and hollow microspheres, wherein the organosilane-functionalised colloidal silica comprises silica particles with one or more organosilane moieties bound to their surface, and wherein the hollow microspheres comprise a polymeric shell. The present disclosure also relates to substrate coated with the coating composition, and to a method for making such a coating composition. The present disclosure further relates to the use of an organosilane-functionalised colloidal silica and/or hollow microspheres in a cool roof or solar reflective coating composition, for improving properties such as the coating lifetime and ageing characteristics, the storage stability, the tensile strength, the reflectance of radiation over the range of about 280 to 2500 nm, the wet and/or dry adherence, and the dirt pick-up resistance to hydrophilic and/or hydrophobic materials.
