止性能が得られないという欠点を持っている。Silicone-based anti-adhesion agents have the drawbacks of low anti-adhesion properties and poor solder characteristics, resulting in poor electrical conductivity. Further, since conventional fluorine-based polymer anti-adhesion agents have poor solubility in general organic solvents, they are used by being dissolved in fluorine-based organic solvents or dispersed in water or general organic solvents. In particular, when the degree of polymerization is large, the solubility in the fluorine-based organic solvent is also lowered and a stable solution cannot be obtained. For this reason,
Sufficient anti-adhesion performance cannot be obtained for a modified or modified epoxy resin having high adhesiveness. Therefore, in order to increase the solubility in the fluorine-based organic solvent or to obtain a stable dispersion in water or a general organic solvent, the average molecular weight of the fluorine-based polymer must be made as small as possible, and therefore the expected adhesion It has the drawback of not being able to obtain preventive performance.
