Poly- tetrafluoroethylene water dispersed liquid composition, poly- tetrafluoroethylene resin film and poly- tetrafluoroethylene resin impregnation body

摘要

The tunic to which as for this invention, crack limited film thickness quite is large, with the paint or impregnation of 1 times also thick film conversion being possible, when the denaturation poly- tetrafluoroethylene is used, crack limited film thickness and is superior in transparency the PTFE water dispersed liquid composition which can form is offered. As for this invention, the poly- tetrafluoroethylene resin particle being the poly- tetrafluoroethylene water dispersed liquid composition which (A) and polyoxyalkylene alkyl ether based chemical compound (B) is included, as for the above-mentioned poly- tetrafluoroethylene water dispersed liquid composition, poly- tetrafluoroethylene resin solid amount density 30 - 70 mass of the above-mentioned poly- tetrafluoroethylene water dispersed liquid composition %, the viscosity in the 25C is below 0.1Pa s, the above-mentioned polyoxyalkylene alkyl ether based chemical compound (B) is 9 - 20 mass sections vis-a-vis the above-mentioned poly- tetrafluoroethylene resin solid amount 100 mass sections, the above-mentioned poly- tetrafluoroethylene resin particle the poly- tetrafluoroethylene resin which (A) is formed is the resin which consists of the denaturation poly- tetrafluoroethyleneIt is the poly- tetrafluoroethylene water dispersed liquid composition which features thing.
