Title:
ETFE塗料用プライマー
Document Type and Number:
Japanese Patent JP4207569
Kind Code:
B2
Abstract:
The first and second aspects of the present invention have their object to provide a coating composition with which a layer mainly comprising a fluororesin and having a thickness comparable to that attainable by the two-coat technique can be formed by one-coat technique, desirably with the fluororesin disposed mainly on the substrate side and the binder resin disposed mainly on the coating film surface side remote from the substrate, and the surface layer thus can be formed in an arbitrary manner and which can be used in a wide range of fields. Thus, the first aspect is a fluorine-containing resin composition obtainable by compounding a macromolecular material with a melt processible fluororesin having an average particle diameter of 0.1 to 30 mu m, wherein a volume ratio between the melt processible fluororesin and macromolecular material is 35:65 - 95:5 as melt processible fluororesin:macromolecular material, and the second aspect is a fluorine-containing resin composition obtainable by compounding a macromolecular material with a melt processible fluororesin having an average particle diameter of 1 to 30 mu m, wherein the macromolecular material is one occurring as a liquid or in a state dissolved in a solvent at below the melting initiation temperature of the melt processible fluororesin and a volume ratio between the melt processible fluororesin and macromolecular material is 35:65 - 95:5 as melt processible fluororesin:macromolecular material. The third aspect of the present invention has for its obj ect to provide a primer of ETFE-based coatings having stable adhesiveness and excellent in processability, which is a primer for ETFE-based coatings comprising an ETFE (A) , a heat-resistant resin, a dispersion medium and a heat-resistant resin-dissolving solvent for dissolving the heat-resistant resin, wherein said ETFE (A) has an average particle diameter of 0.1 to 30 mu m and, a solid matter content ratio between said ETFE (A) and said heat-resistant resin is 40:60 - 90:10 on the mass basis.
