FT. WAYNE, IN--(Marketwire - June 23, 2008) - Trelleborg SealingSolutions, a worldwide leading supplier of high-quality sealing andbearing systems, announces the launch of a range of coloredcoatings for O-rings. Based on superior coating technology, thesesurface treatments are ultra-thin and resistant to cracking andpeeling. Allowing segregation of similar seals, they demonstratealmost the same properties as comparable clear coatings,facilitating both push-fit and automated assembly.
As O-Ring materials are usually black, one seal may appear almostidentical to another, but can vary slightly in dimension or be ofdifferent compounds. A large number of O-Rings may be used in oneassembly. This is especially the case in automotive componentmanufacturing, and installing a seal in the incorrect location cancause leakage or even seal failure. An effective and easy means ofsegregation within a production facility is therefore critical toensure there are no mix-ups and color-coding is one of the bestways of segregating O-Rings. In addition, as lighter colors can bemore easily detected within a black or dark assembly, they can alsoaid end-of-line quality checking.
"Colored coatings are ideal for differentiating seals withinproduction facilities, and Trelleborg Sealing Solutions offers whatwe believe is the widest range of colored coatings available asstandard from one seal supplier," says Simone Frick, ProductEngineer for O-Rings. "Much research has been involved in thedevelopment of these surface treatments. Ultra-thin, they have nonegative effect on the performance of the elastomer O-Ring and havethe benefit of enhancing friction characteristics. Offeringsuperior resistance against cracking, unlike some competitiveproducts, they are virtually impossible to peel from theirsubstrate."
Like clear coatings, the colored coatings improve the frictioncharacteristics of elastomer O-Rings. Depending on the surfacetreatment, they can make a once only push-fit assembly easier orfacilitate automated assembly, preventing the O-Rings stickingtogether during this process.
Trelleborg Sealing Solutions provides a wide range of readilyavailable colored coatings, including turquoise, pink, brown,green, white, blue, yellow, orange and red. The surface treatmentscan be applied to most seals, standard or custom, in the majorityof elastomer compounds.
