Xylar 2 Coating /Aluminum-filled ceramic-metallic coating for stud bolt

Xylar® coatings are thin-film surface protection finishes, ideal for extending the lives of parts where environments are extremely hot, corrosive and/or abrasive. Xylar is often used on stud bolt,fasteners for high temperature and anti-rust conditions

Based on an alloy of ceramic and metallic materials, Xylar® forms a thin, hard, high-temperature-stable, sacrificial ceramic metallic barrier. In many cases, these coatings enable parts to be used in environments that would normally preclude their use. In others, they enable designers to replace expensive super alloys with less costly metal coated with Xylar®.

Xylar coatings have in common an inorganic, ceramic-metallic bonding agent rather than the organic polymer resins used in Xylan coatings. The ceramic-metallic cornerstone creates coatings which are much harder than their organic counterparts and have the potential for much higher operating temperatures, depending upon the fillers and additives selected for use in the coating. They provide exceptional thin-film corrosion protection and are often top-coated with one of the lubricated Xylan coatings. Xylar can also be used alone when a lubricated surface is not needed.

Xylar 2® is nearly twice as durable as the best organics. An inorganic ceramic-metallic coating, it is known to protect metals from high temperature oxidation and corrosive salt environments.

Xylar 2 is a combination of ceramic materials and aluminum metal fillers. It tends to become a metallic/ceramic coating (cermet) on curing.

Xylar 2 is an inorganic ceramic-metallic coating which was originally designed to provide the aerospace and marine industries with a product that would protect components from galvanic corrosion, high temperature, oxidization, salt laden atmospheres, chemicals and abrasives.

Due to its thin film build and extremely high corrosion resistant properties, Xylar 2 is of particularly great use as a primer for Xylan topcoats on fasteners, threaded components and other low tolerance applications.

Excellent heat resistance (up to 650⁰C) makes it an ideal solution for engine applications where the electrical couple between dissimilar metals could result in corrosion.

Xylar® coatings are recommended for using in below conditions.

• Protecting metal from oxidizing due to water in all forms (salt water, steam, ice, etc.)
• Protecting metal from high temperature oxidation up to 1000°F
• Providing a sacrificial primer for conventional air spray lubricating coatings, such as Xylan®

Xylar 2 Basecoat: a slightly different chemical composition from Xylar 1, although it remains a “cermet”. This modification produces a coating which is easier and more forgiving to apply

Xylar 101: utilizes nonmetallic fillers in combination with the basic ceramic materials. Properly applied and cured, Xylar 101 becomes a sealer for the Xylar basecoats described above and enhances the smoothness and salt-spray resistance of the basecoat formulae. The function of Xylar 101 is to inhibit the rate of sacrificial degradation

Handling of Xylar Coatings

All Xylar® coatings, including Xylar 1, 2, 101 and 201 contain chromic acid as anadhesion promoter.  These materials are very acidic and corrosive and also react as an oxidizer.  In addition, chromic acid is a carcinogen.  Therefore, special precautions must be observed when using and disposing of these materials in order to protect the application equipment and the health and safety of workers and to prevent pollution of the environment.
