Electrical insulator coatings

Polyesters are also used in continuous filament spunbonded nonwovens (see Nonwoven fabrics). Reemay spunbonded fabric is composed of continuous filament PET with a polyester copolymer binder. These spunbonded fabrics are available in a wide range of thicknesses and basis weights and can be used for electrical insulation, coated fabric substrates, disposable apparel for clean rooms, hospitals, and geotextiles (qv). 

Cathodic protection cannot work with prestressed concrete structures that have electrically insulated, coated pipes. There is positive experience in the case of a direct connection without coated pipes this is protection of buried prestressed concrete pipelines by zinc anodes [38], Stability against H-induced stress corrosion in high-strength steels with impressed current has to be tested (see Section 2.3.4).

Copolymers (S acrylonitrile have been proposed for a large variety of other industrial applications. These include adhesives, electrical insulation, coatings for leather, paper, and textiles, impregnating agents for paper, and components of surface coatings. 

Fatty bisamides are used primarily to increase slip, reduce blockiog, and reduce static in polymeric systems. Other specialty appHcations include cosolvents or coupling agents for polyamide resins, fillers for electrical insulation coatings, additives for asphalt to reduce cold flow, and synthetic waxes for textile treatments (68). Bisamides have been used in all the traditional primary amide applications to increase lubricity and have become the amide of choice because of their better efficiency. Bisamides have the highest commercial value in the amide market. 

Assuming that the protection system consists of a combination of coating and cathodic protection, the required current for protection is multiplied by the coating breakdown factor, /j, which is the anticipated reduction in cathodic current due to the application of an electrically insulating coating. Total initial, average, and final current will be adjusted with the initial, mean, and final coating breakdown factors,and/jp, respectively [4], Total initial current ...

Poly(imide-co-amides) are easier to produce and to process than aromatic polyamides or polyimides. Like these, they are used in particular for electrical insulation coatings. As the ratio of imide/amide increases, the thermal stability of the copolymers increases, but the flexibility of the product deteriorates.

Uses. Owing to their excellent adhesion, they are used extensively as primers for most coatings and finishes over most substrates. Epoxy coatings and finishes provide excellent chemical and corrosion resistance. They are used as electrical insulating coatings and finishes because of their high electric strength at elevated temperatures. Some of the...
