Provided is a coating film having excellent durability and wear resistance, and utility as mold surface release coating. The coating film has excellent releasability (non-adhesiveness) over a long period of time. Further provided is a coating composition capable of forming such a coating film, the coating composition containing a fluoropolymer and an oil that is a liquid at 25° C., wherein the decomposition temperature of the oil is higher than the melting point of the fluoropolymer.

Fluoropolymer coating composition

This application provides a coating film having excellent durability and wear resistance that, when applied to a mold surface, has excellent releasability (non-adhesiveness) over a long period of time, and a fluoropolymer coating composition that is able to form such a coating film. The fluoropolymer coating composition contains a fluoropolymer and a fluoro oil, where the decomposition temperature of the fluoro oil is higher than the melting point of the fluoropolymer.

An object of the present invention is to provide a heat shrink tube excellent in peelability and transparency, and a method for producing the heat shrink tube. The present invention provides a peelable heat shrink tube comprising a composition containing a melt-processable fluororesin and PTFE, the PTFE lacking a heat history of its melting point or higher after polymerization and having a specific gravity, as measured according to ASTM D4894, of 2.20 or less. The content of the PTFE is 0.05 to 3.0 wt % based on the total weight of the melt-processable fluororesin and the PTFE. The present invention also provides a method for producing the tube which comprises melt-extruding the composition at a temperature lower than the melting point of the PTFE.
