Title:
COATING MATERIAL COMPOSITION
Document Type and Number:
Japanese Patent JPH01108270
Kind Code:
A
Abstract:

PURPOSE: To obtain a coating material composition giving a film which has excellent weatherability and hardly causes stained spots or streaks and from which the stains can be readily removed, by using a specified fluoro-copolymer as its constituent.

CONSTITUTION: This coating material composition comprises a fluoro-copolymer made by copolymerizing 30W70mol% fluoro-olefin (A) (e.g., chlorotrifluoroethylene or tetrafluoroethylene) with 70W5mol% N-vinyl-lactam compound (B) (e.g., N-vinyl-2-pyrrolidone), 2W40mol% monomer (C) having crosslinkable functional groups (e.g., ω-hydroxybutyl vinyl ether), and 0W63mol% monomer (D) copolymerizable therewith. This composition can give a coating film which has excellent weatherability and hardly gives rise to conspicuous stained spots or streaks, these defects having been the problem in conventional weatherproof coating material, and from which the stains can be readily removed. In addition, since the coating film does not repeal a water-base marking ink, this composition can also be used for, e.g., the surface coating of both interior and exterior indicator panels.
