Title:
NON-AQUEOUS DISPERSION OF POLYTETRAFLUOROETHYLENE
Document Type and Number:
Japanese Patent JP2021004322
Kind Code:
A
Abstract:
To provide a non-aqueous dispersion of polytetrafluoroethylene which has a fine particle diameter and low viscosity and is excellent in storage stability even when a surfactant including a fluorine group and a dispersant are not added to the non-aqueous dispersion, and which can impart resistance against roughening solution to a cured material of the non-aqueous dispersion of polytetrafluoroethylene such as an electric board, and which is suitable for a composition for a circuit board, a composition for a circuit board adhesive, and the like enabling copper plating for the circuit board wiring and the like to be easily formed on a resin cured article.SOLUTION: A non-aqueous dispersion of polytetrafluoroethylene is provided that comprises at least: an acrylic resin dispersion stabilizer containing at least one monomer selected from the following group A and synthesized; polytetrafluoroethylene; and a non-aqueous solvent, and that has an average particle diameter of 1 μm or less, the average particle diameter being measured by a dynamic light scattering method in a non-aqueous dispersion (an average particle diameter by a cumulant method analysis in scattered strength distribution). Group A: methyl (meth)acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, t-butyl (meth)acrylate, 2-methylpropyl (meth)acrylate, cyclohexyl (meth)acrylate, benzyl (meth)acrylate, triethylene glycol di(meth)acrylate, butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, and 6-methylheptyl (meth)acrylate.SELECTED DRAWING: None
