Xylan Coating
Xylan coatings provide tailored properties to functioning surfaces. Xylan coatings provide lubrication and controlled friction, wear resistance, heat resistance, nonstick and release properties and, at the same time, can also protect from corrosion.
Xylan coatings solve the problems created when the ideal material for use in engineering construction has the wrong surface properties. Parts made from materials with optimum strength, weight and cost may corrode, seize or adhere. Xylan coatings provide the working surface, tailored to the application.
General Principles for the use of Xylan coatings
Xylan is a family of products designed to suit a wide range of applications such as:
Use as a lubricant and wear-resistant coating...
Thin film Xylan coatings (20-30microns) change dimensions so little they can be incorporated into existing designs. “Dry lubrication” applications (light load/continuous movement, or limited movement under high pressure) include carburetor choke spindles, seat belt mechanisms, pins and linkages, print head rails, guide rails and solenoid plungers. “Wet lubricated” applications include fuel pump and refrigerator compressor motors and end plates for gear pumps. In “wet lubricated” applications, both pressure and velocity can be increased. Unlike oils and greases, Xylan provides a permanently bonded lubricant film.
Use as a seal...
Sealing applications for both liquids and gases include: ball and plug valves, hydraulic pistons and cylinders and pneumatic valve actuator cylinders. Xylan coatings are also useful on cylinder head gaskets and pipeline flange seals.
Use in materials handling...
Xylan coatings can be used to reduce clogging and buildup in materials handling equipment such as screw conveyors, hoppers, chutes and slides.
Use under conditions of corrosion...
A range of Xylan coatings has been developed which offer the above properties under corrosive conditions. Salt spray resistance (ASTM B 117) from 240 to 3000 hours can be achieved. A typical application is the coating of threaded fasteners for the chemical and offshore oil industries.
Color...
Xylan coatings can be made in many colors to match their surroundings, for color coding, or to provide functional surfaces. Fashion has become an ever increasingly important part of our lives. Today, computers, mobile phones, watches and many other utilitarian items have turned to fashion to attract the customer’s eye.
Fashion is not new in the fields of consumer vehicles (automobile and motorcycles). The use of chrome, several colors on the same body, brightly painted designs, burled walnut panels, leather seats and “designer” editions have been around for years.
The magic of color...
The manufacturer of the largest, most complete line of fluoropolymer coatings in the world has just introduced a new line of premium coatings that revolutionized these forgotten items. Introduced at the 2003 SAE show in Detroit, the coatings are marketed under the name of Xylan® 2222.
These new coatings take colors to a new level. Metallic and pearlescent, they are also iridescent and, under light, will shift shades accordingly. These coatings are waterborne and environmentally friendly. They also offer Xylan® 2322, the solvent-borne equivalents.
These new coatings are available in everything from silver to bronze, from metallic reds to greens and blues and yellows. These coatings can be color matched to any of the items on the car or motorcycle. So a dashboard surround, for example, can be colored to match the dash exactly. So, of course, can all the strips of flexible rubber and EPDM. Motorcycle seats can be colored to match – or contrast in a special fashion statement with – the colors of the bike.
A lot more than color...
New Xylan® 2222 and 2322 coatings offer protection from ultraviolet lights, excellent freeze-release, low friction, and superb resistance to abrasion. These coatings are environmentally friendly and are single component products. They are applied to many types of substrates including EPDM, natural rubber, NBR, TPVs, vinyl, leather, etc. Once cured, they can be used at temperatures from -40ºF to +450ºF.
