Coating composition for vibration damping, and method for producing the same

摘要

Provided is a coating composition for damping purposes, capable of forming the thin film applicable to damping and sound absorption at a vibration- or sound-generation section of complex shape, which comprises the following coating components (i), (ii) and (iii): (i) a resin emulsion containing a polar group capable of forming the coating film containing the hydrogen bond which is formed when the polar group comes into contact with an aromatic compound as the following coating component (ii) having the hydrogen bond forming effect, (ii) an aromatic compound which has the effect of forming and controlling the hydrogen bond, and also has at least one hydroxyl group in the molecule, and (iii) an inorganic filler, and also provides a method for producing the same. Also a method of producing the coating composition is provided.
