Coating protects insulators from contamination

Sylgard high-voltage insulator coating (HVIC) from Dow Corning is a one-part silicone dispersion coating designed to improve the performance of porcelain and glass high-voltage insulators, arresters and other components, especially where surface contamination causes arcing problems. Offering the ability to recover its water repellancy after surface electrical activity, the smooth elastomeric coating helps the insulator stand up to the effects of moisture, salt spray and contaminants. Applications include line and station insulators, bushings, instrument transformers and related devices. The coating delivers a dielectric strength of 18 kV/mm at 1.3 mm (460 V/mil at 50 mils) and a dielectric constant of 3.08 at 100 kHz.

Protective coating is harder than steel

Recently issued by General Magnaplate is a brochure describing a full line of synergistic coatings that put a harder-than-steel, permanently dry-lubricated surface on critical component parts made of ferrous and non-ferrous metals. Pioneered for use in space projects, these surface enhancements provide reliable performance and long service under the most difficult operating conditions. The four-page, two-colour Brochure #40 describes Tufram, Nedox, Plasmadize, Lectrofluor, Magnaplate HMF, Magnaplate HCR, Canadize, Magnadize, Goldenedge, Hi-T-Lube, Magnagold, Magnaplate TNS and Magnaplate HTR coatings. These coatings, many of which are USDA/FDA/AgriCanada-compliant for use on food and pharmaceutical equipment, become an integral part of the metal surface, protect against corrosion and abrasion, improve release properties, lubricate in high and low temperatures, and add wear life to steel stainless steel, copper, magnesium, titanium and many alloys. Included in the brochure are 15 examples of applications.

Galvanizing spray stops rust in extreme conditions

STS ZnKote Galvanizer cold galvanizing coating prevents oxidation on iron and other ferrous metals by electro-chemically bonding with the metal surface to form a tough, protective coat. Effective both indoors and outside, this 95% pure zinc spray is quick drying, has good adhesion properties and protects bare metal for up to three years. When used as a base coat, it will not crack, peel or yellow, even under extreme environmental conditions. Packaged in 9-oz aerosol containers, it contains no 1,1,1-trichloroethane, CFCs or other ozone-depleting solvents. Applications include galvanizing metal parts, touching up old galvanized coatings and forming primer coats over bare metal in preparation for finished coatings.

Coating keeps couplings working in outer space

In the harsh vacuum and low temperatures of space, the valves on quick disconnect couplings on the International Space Station must operate with total reliability. Surface hardness, durability and extended reliability are of utmost importance for the couplings installed both inside and outside the space station. Design engineers at Parker Stratoflex Unit of Parker Hannifin achieved these qualities by specifying that the surface of the quick disconnect couplings be treated with Nedox, a surface enhancement coating technology applied by General Magnaplate. This coating, which offers top performance at a low cost, provides an extremely thin coating that dry-lubricates the surface to a co-efficient of friction as low as 0.06 while providing a hardness of up to Rc68.

Self-lubricating cartridge is for monorail guideways

Schneeberger has released the SLC lubrication cartridge, a monorail accessory. This self-contained cartridge supplies a continuous flow of lubricant to the critical surfaces of the company’s profile linear guideways. For light- to medium-duty applications, the cartridge can replace the central lubrication system and minimize the scheduled re-lube maintenance associated with any recirculating roller product. It attaches to one or both sides of a standard recirculating roller carriage and will work in any carriage orientation. The cartridge’s reservoir holds sufficient lubricant for more than 3,000 miles of travel before refilling is required.
