Below is a detailed comparison of the Xlyan-Coated Allen Bolt with several other coatings to assist customers in making informed choices:
1. Zinc Coating
Zinc coating involves electroplating a layer of zinc onto the bolt surface, creating a protective barrier that prevents direct contact between the base material and corrosive media. According to ASTM B633 standards, the zinc coating thickness typically ranges from 5 to 25 microns, providing excellent atmospheric corrosion resistance, particularly in humid or mildly corrosive environments. Salt spray tests (ASTM B117) show that zinc-coated bolts can withstand corrosion for 100-200 hours.

Salt spray tests (ASTM B117) show that zinc-coated bolts can withstand corrosion for 100-200 hours.
2. Phosphating
Phosphating converts the bolt surface into a phosphate film layer, enhancing adhesion to coatings or lubricants while providing some rust resistance. The phosphate film thickness is generally 1-3 microns, making it suitable for moderate corrosion environments, such as mechanical equipment or indoor applications. Its salt spray test corrosion resistance time ranges from 24 to 72 hours.

3. Dacromet Coating
Dacromet is an electrolytic-free coating technology that applies a layer of zinc-aluminum flakes and chromates to the bolt surface, forming a dense protective film. The coating thickness typically ranges from 6 to 10 microns, offering extremely high corrosion resistance. Salt spray test results show a corrosion resistance time of 500-1000 hours or more, making it suitable for high-temperature, high-humidity, or highly corrosive environments, such as marine engineering or chemical equipment.

4. Xlyan Coating
Xlyan (Polytetrafluoroethylene) coating is a high-performance polymer coating with an extremely low friction coefficient and excellent chemical inertness. The Xlyan-Coated Allen Bolt typically has a coating thickness of 10-30 microns and remains stable in strong acids, strong alkalis, or high-temperature environments (up to 260°C). It also provides self-lubricating properties, reducing thread wear. Its corrosion resistance far exceeds that of traditional coatings, making it ideal for extreme working conditions.
