FluoroKote #1®: a superior fastener coating

The product of thirty years' expertise in industrial coating, Metal Coatings Corporation's exclusive FluoroKote #1® fluoropolymer coating far outperforms standard products in fastener protection. This means a lower coefficient of friction for quick, easy application, and reliable removal with ordinary wrenches even under extreme exposure to salt water or corrosive chemicals. A unique three-step coating process insures both consistent coating and excellent adhesion, even on the difficult-to-coat inside of threaded parts. FluoroKote #1® offers all this at costs that are comparable or less than standard fluoropolymer coatings.

A unique three-step coating process

The FluoroKote #1® application process begins with surface preparation, using the latest industry technologies to thoroughly remove all, rust, scale, manufacturing oil and contaminants. A series of coatings are then applied:

1. A metallic base coat, for added protection in the event of top coat damage
2. An adhesion coat to create a powerful chemical bond between base and top coats
3. A heat-cured, custom-formulated fluoropolymer coating containing PTFE

This rigorous process allows Metal Coatings Corporation to guarantee 100% coverage of fastener surfaces, including the inside of nuts commonly unreached by standard coatings.

FluoroKote #1® applications

The unique benefits of FluoroKote #1® make it valuable in many types of fastener applications:

• The most popular application is on B7 studs and 2H nuts, used at chemical plants, refineries and offshore platforms. The coating's chemical resistance and easy on/easy off characteristics are perfect for these environments
• Water utilities take advantage of FluoroKote #1®'s superior corrosion resistance by coating T-head bolts for underground service
• Stainless steel fasteners, used in many different industries, are coated for lubricity and anti-galling

In addition, the coating has been applied in hundreds of other specific applications, including:

• Oxygen Service
• Phosgene gas lines
• Boiler rooms
• Gas meters
• Anhydrous HCL
• Insulated and non-insulated piping
• Monochlorobenzene (MCB)
• Formaldehyde
• Aniline
• Steam
• Water lines
