A wire harness pipe includes an aluminum pipe, a heat shrink tube that coats the outer surface side of the aluminum pipe, and an adhesive layer that is disposed between the aluminum pipe and the heat shrink tube.

Resin-coated wire harness pipe

A fluororesin-coated article having excellent corrosion resistance is disclosed, which comprises a base plate having a finely roughened surface and having thereon a layer of a fluororesin composition containing a fluororesin comprising a mixture of a heat-fusible fluororesin and PTFE, the content of the heat-fusible fluororesin in the mixture being 2% by weight or more but less than 12% by weight based on the total amount of the fluororesin. The fluororesin composition layer may contain an inorganic pigment in an amount of 1 to 25% by weight based on the total amount of solid components of the composition. A fluororesin-coated article free of pinholes in its coatings is also disclosed, which comprises a base plate having thereon a fluororesin coating and further thereon a surface layer containing substantially no pigment and adhesion aid and comprising a mixture of a heat-fusible fluororesin and polytetrafluoroethylene, the content of the heat-fusible fluororesin being 2% by weight or more but less than 12% by weight based on the total amount of the mixture.

Fluororesin-coated article

A fluororesin-coated material having markings indicated thereon is disclosed, which material comprises (1) a substrate having coated thereon a fluororesin composition comprising a high-molecular weight material having a benzene ring and at least one of a nitrogen atom, a sulfur atom and a carbonyl group in the main chain thereof, or (2) a substrate having coated thereon the high-molecular weight material, and further having coated on the high-molecular weight material a fluororesin composition. The markings are indicated on the coated material by irradiating the coated surface of the coated material with electromagnetic waves having a wavelength of 600 nm or less to thereby cause a change in the color of the high-molecular weight material at irradiated parts and provide a difference in color between the irradiated parts and unirradiated parts.

Fluororesin-coated material having markings indicated thereon

A fluororesin coating composition comprising a liquid medium having dispersed therein (A) fluororesin particles having an average particle diameter of 5 .mu.m or more and (B) fluororesin particles having an average particle diameter of 1 .mu.m or less. In the coating composition, the proportion of the fluororesin particles (B) based on the total amount of the fluororesin particles (A) and (B) being from 20 to 80% by weight. The fluororesin coating composition is excellent in both film-forming properties and stability.
