Durable Water- and Moisture-Proof Coating Composition

摘要

The present invention relates to a polymer obtained by radical polymerization of (I) a fluoroalkyl group-containing acrylic ester having a fluoroalkyl group ester-bonded to a carboxyl group directly or via a divalent organic group and having a substituent at the? ) In the presence of the polymer obtained by radical polymerization of the monomer component containing the fluoroalkyl group-containing acrylic acid ester and the alkoxysilyl group-containing radically polymerizable monomer, or (2) the alkoxysilyl group-containing mercaptan, the fluoroalkyl group- And (II) a fluorine-based solvent, which is obtained by radically polymerizing an ester of a fluorine-containing polymer. According to the present invention, it is possible to obtain a coating composition capable of forming a coating film having excellent waterproofing and moisture-proofing performance excellent in durability against various substrates, particularly electronic parts.
