A method for synthesizing calcium-silicate-based porous particles (CSPPs) is described. Control over CSPP morphology and pore size is achieved through a refined solution-based synthesis, allowing loading of a variety of sealants. These particles, upon external stimuli, release the loaded sealant into the surrounding material. Methods of loading the CSPPs with loading sealant are described. The CSPPs may be used in pure form or mixed with another material to deliver self-healing, sealing and multi-functional properties to a physical structure. The composition of the CSPPs is described, along with methods of use of the CSPPs.

A coating composition includes a binder component (A), a flake-like aluminum pigment (B) having an average particle diameter (d50) of 18 m to 25 m, and a flake-like pigment (C) being a flake-like pigment other than flake-like aluminum pigments and having an average particle diameter (d50) of 8 m to 30 m. A content of the flake-like aluminum pigment (B) is 10 parts by mass to 50 parts by mass and a content of the flake-like pigment (C) is 0.5 parts by mass to 10 parts by mass, based on 100 parts by mass of the binder component (A). A content ratio (B)/(C) of the flake-like aluminum pigment (B) to the flake-like pigment (C) is 2/1 to 50/1 in terms of a solid content mass ratio.
