XYLAR 1 and XYLAR 2

A type of coating made of ceramic metal, Xylar 1 provides high resistance to oxidation even at high temperatures as well as long-term protection against salt fog.

This coating can be used directly without any post-treatment. Generally, it is applied as the base coat for materials following a top coat. Whitford’s Xylan 1070 is typically this top coat. Xylan 1070 is also known as fluoropolymer coating and is a PTFE coating. Based on a specific organic solvent, it was first developed during the early 1970s to coat fastening materials.

The unique combination of Xylar 1 and Xylan 1070 offers excellent protection against corrosion and withstands the neutral salt spray test for almost 4000 hours. Coefficient of friction is very low as well, for instance, lower than electrolytic zinc plating. These two coatings are approximately 50 mu thick (combined layers thickness).

For Xylar 1, it is possible to use the processed materials at temperatures between -195° C to +535°C.

For Xylan 1070, it is possible to use the processed materials at temperatures between -195° C and +260° C.

Xylar 2 / Xylan 1070 PTFE-coated stud bolts

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.

Initially, Xylar 2 was designed exclusively for aircraft & aerospace applications. A second-generation cermet, it offers a hard barrier coating which is capable of rupturing the electrical path between unlike metal components.

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 applications

Xylar 2 offers the marine and aerospace industries with materials to safeguard components from oxidization, high temperature, salt laden atmospheres, abrasives and chemicals.

The thickness of Xylar 2 makes it reach 10000 hours with minimal red rust in salt fog. Moreover, Xylar 2 stands up to 1100°F/600°C of uninterrupted use.

As mentioned earlier, Xylar 2 finds its use in the marine and aerospace industries. It is used as thermal barrier in case of automotive engine & exhaust parts.
