▎ 摘　　要

NOVELTY - A composition comprises a solvent-borne monomers, a diluent, a sufficient amount of an adhesion promoter to provide a coating formed from the composition having a substrate adhesion of at least 3 MPa when measured according to , an overcoat adhesion of at least 3 MPa when measured according to , or coat adhesion window of at least 4 hours when measured according to , a sufficient amount of rheology modifier to provide a coating formed from the composition having anti-settling, anti-sagging, or surface-leveling properties and a sufficient amount of a ceramic performance additive to provide a coating having a reduced noise radiation of 2-10 dB per about 100 pm of coating thickness at frequencies of 10-10 kHz when measured on a 3 mm thickness cold rolled steel metal plate relative to a 3 mm thickness cold rolled steel metal plate or a hardness of at least 5 H when measured according to . USE - Composition for coating on substrate e.g. surface of marine vessel, such as boat or ship or marine equipment, such as sensor or propeller or surface of marine vessel hull for reducing underwater radiated noise and for reducing cavitation (all claimed). ADVANTAGE - The composition provides the cured coating having improved sound dampening properties, hardness, substrate adhesiveness, overcoat adhesiveness, recoat adhesiveness, or bending strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a coating, which comprises a reaction product of the composition and a hardener.
