Xylan Zinc Rich Coated Fasteners

Stud Bolts, Nuts, Screws, Threaded Rod & Washers

Xylan Zinc Rich coated Fasteners like Stud Bolts, Screws Nuts, washers & bolts are commonly used in the Automotive, Construction and Wind Power industries where corrosion resistance is of paramount importance.
With the corrosion resistant Zinc Rich coating, Xylan®️ system advantages can be gained with technical advantages compared to galvanic plating, as well as a one stop shopping service provided by WHITFORD.

Features of Xylan Zinc Rich Coatings

• The basecoat is a premium inorganic coating containing zinc or zinc-alumium flakes.
• These coatings have excellent corrosion resistance (<1,000 hours SST at 8-12 microns).
• They have an attractive silver appearance.
• The application processes eliminate any problems of hydrogen embrittlement.
• The cost of application is very competitive.
• They are more environmentally friendly because they are free of harmful heavy metals such as Cr-(VI), cadmium, cobalt, lead and nickel.
• With a Xylan topcoat, they offer a consistent good coefficient of friction (µtot of 0.08-0.20).
• Xylan series topcoats can also be combined with zinc-rich coatings to provide even better corrosion resistance and barrier protection.

Xylan Zinc Rich Application Method & Parameters

Xylan zinc-rich coatings may be applied using conventional spray or the dip/spin system, a cost-effective bulk method. Important parameters:

• Application viscosity: 15-30s (depending on application method)
• Cure temperature: 240-270˚C
• Cure time: 15-30 minutes
• Recommended cure: 30 min at 250˚C part-metal temperature.
