Title:
WATER-BASED COATING MATERIAL COMPRISING CORE/SHELL FLUOROCOPOLYMER AND PRODUCTION OF THE SAME COPOLYMER DISPERSED IN AQUEOUS MEDIUM
Document Type and Number:
Japanese Patent JP3146842
Kind Code:
B2
Abstract:
PURPOSE: To obtain a water-based coating material excellent in film-forming properties, water resistance and staining resistance by dispersing a specified core/shell fluorocopolymer in an aqueous medium.
CONSTITUTION: The material is prepared by dispersing in an aqueous medium a core/shell fluorocopolymer having a core/shell weight ratio of 20/1 to 1/2 and a two-layer structure composed of a core comprising a fluorocopolymer mainly consisting of repeating units derived from a fluoroolefin monomer and repeating units derived from a vinyl carboxylate monomer and having a Tg of 40°C or above and a shell comprising a fluorocopolymer mainly consisting of repeating units derived from a fluoroolefin monomer and repeating units derived from a vinyl carboxylate monomer and having a Tg of 5-30°C.
