The electrode activator's binder is made of a fluoroplastic grafted with at least one acrylic polymer.

Fluoroplastic dispersions are then applied as second coatings to the profiled second surfaces.

Fluoroplastic dispersions are applied as first coatings to the first surfaces of the textile.

Following application, the fluoroplastic layer is heated and the curable elastomer layer is cured (e.g., thermally cured).

Preferably, the elastomer cure occurs separately from and subsequent to heating the fluoroplastic layer.

The main constituents of the coating (5) include polymer material, fluoroplastic, solid lubricant and wearable inorganics.

The stator windings are impregnated and are covered by a film of waterproof polyamide, inside which is a layer of fluoroplastic.

Following application, the fluoroplastic layer is heated and the curable elastomer layer is cured (e.g., thermally cured).

Prior to application of the fluoroplastic composition, the curable elastomer layer is thermally insulated to prevent it from undergoing substantial heating.

Preferably, the elastomer cure occurs separately from and subsequent to heating the fluoroplastic layer.

An extruded innermost semi-conductive layer of a fluoroplastic has a surface resistivity in the range of 10?1 to 106¿ ohm/sq.

The fluoroplastic has an MFI no greater than 5g/10 min., and/or an average particle size greater than 100 nm.

A method for enhancing the bond strength between a VDF-containing fluoroplastic layer and an elastomer layer of a multi-layer article.

In an alternative embodiment, a tube is formed from an inner layer of a THV fluoroplastic polymer and a cover layer of a relatively thick elastomeric polymer.

An inner permeation-resistant layer of a fluoroplastic is coextruded around the innermost layer at temperatures below 600 degrees Fahrenheit.
