Abstract

The present disclosure envisages a coating composition. The coating composition comprises a polymeric emulsion, silane functionalized fibres and a fluid medium. The silane functionalized fibres are present in an amount in the range of 0.05 wt. % to 10 wt. % of the coating composition. The polymeric emulsion is present in an amount in the range of 20 wt. % to 60 wt. % of the coating composition. The fluid medium is present in an amount in the range of 5 wt. % to 40 wt. % of the coating composition. The silane functionalized fibre comprises at least one polymer bonded to at least one silane group. The coating composition of the present disclosure exhibit improved properties such as better coverage when applied on a surface, mechanical properties, stain resistance properties and the like, when compared to coating composition without fibres.
