Product Description Product DescriptionFluorocarbon Coating (PTFE, Xylan)Fluorocarbon Coating is an organic coating consisting of solid lubricant dispersed in an organic binder and dissolved in a specially formulated mixture of solvents. It is also corrosion-resistant due to the use of a thermally cured thermosetting synthetic binding material. When applied to the substrates it resists galling, seizure and fretting and offers corrosion resistance.XYLA-N coatings were originally developed out of fluroplastics (PTFE, etc ) but with continued development of polymers that can be used as binder systems and adhesion promoters , the performance of coatings has improved considerably .Xyla-n? 1070 is a low friction coating with high corrosion resistance to oxidation and high temperatures. Similar to Xylan? 1427, this PTFE coating is ideal for leak prevention for tanks, valves, vessels, etc. in harsh environments.XYLA-N 1070? Its basic use is for fasteners in marine use, in particular for drilling platform construction in the north sea . its main features are that it combines good corrosion protection with dry lubrication. The main benefits are:- significantly reduced torque required for a given pre- load.? Much greater accuracy of pre- load for a given applied torque.? Good protection against salt water corrosion ease of break - out of nuts (prevention of nut seizure) leading to ease of maintenance.XYLA-N 1070 coated Stud bolt production procedureSTEP ONE: Applying a base-coat such as Zinc-plating, Zinc-Nickel. The base coat has an average thickness of 10-15μSTEP TWO: sand-shot blasting to roughen the surface of the fasteners to be coated.STEP THREE: Having fasteners coated with PTFE Xylan 1070 or Xylan 1424 in the required color. See the table below for the top coat most suited to for your situation.Top coatComments:ASTM B-117 Salt Spray testWorking Temperature Xylan 1424. Fluoropolymer Organic. Water-based.

In a ASTM B-117 Salt Spray test the coating remains resistant up to 3900 hours before red rust occurs.Sustainability. As we are working towards a circular economy, PTFE coated fasteners are more sustainable then regular bolts due to their longer durability.Lower maintenance costs. Longer durability of bolts does not only result in more sustainability but also lower maintenance costs.Low torque friction coefficient. Due to the TEFLO-N top layer, torque friction is low.Added value. Using colored bolts into the colored frame work, valve, flange or heat exchanger gives your product extra added value.We have an extensive range of plating and coatings that provide outstanding temperature, chemical, abrasion and corrosion resistance designed to withstand harsh conditions.

To be more specific, ASTM A193 B7 alloy steel is a high temperature grade of A-193. B7 steel is also a chrome moly steel with a minimum tensile strength of 125ksi. Depending on your unique project requirement needs, grade B7 bolts can be used in numerous types of extreme conditions.ASTM A193 B7 stud bolts are ideal for industrial and structural bolting application with high-temperature or high-pressure service environment.

In a ASTM B-117 Salt Spray test the coating remains resistant up to 3900 hours before red rust occurs.Sustainability. As we are working towards a circular economy, PTFE coated fasteners are more sustainable then regular bolts due to their longer durability.Lower maintenance costs. Longer durability of bolts does not only result in more sustainability but also lower maintenance costs.Low torque friction coefficient. Due to the TEF-LON top layer, torque friction is low.Added value. Using colored bolts into the colored frame work, valve, flange or heat exchanger gives your product extra added value.3 How do you apply Xylan Coating? STEP ONE: Applying a base-coat such as Phosphate, Zinc, Zinc-Nickel, Hot Dip Galvanized or Xylar 1. The base coat has an average thickness of 10-15μ (except for HDG).STEP TWO: Glass-shot blasting to roughen the surface of the fasteners to be coated.STEP THREE: Having fasteners coated with PTFE Xylan 1070 or Xylan 1424 in the required color. See the table below for the top coat most suited to for your situation.STEP FOUR: Heat treatment of the coated fasteners is performed.4.Is Xylan the same as Te-flon?No. Xylan and Te-flon are both brands of PTFE (Polytetrafluoroethylene) coatings. Although some Xylan and Te-flon products may have similar properties, it is important not to assume they will do the same job as there are variations of each product which are suitable for different applications and environments.5.Is Xylan suitable for fasteners?Yes. Amongst the Xylan range are a series of fastener-class coating systems designed to improve the performance and longevity of all types, sizes and grades of fasteners through its excellent corrosion resistant and low-friction properties. Xylan can be applied via dip-spin and spray methods, meaning it is suitable for small screws right through to large stud bolts.6.What is Xylan Blue?Xylan actually comes in a wide range of colours but is often referred to as "Xylan Blue" or "PTFE Blue" in reference to coating B7 Stud Bolts and Nuts for the Petrochemical industry. Generally, the product required will be Xylan 1424 or Xylan 1070 however its always best to clarify with the end user or consult technical advice direct from Whitford or your preferred applicator to confirm.7.What are the addtional coating type you can supply?Zinc + Fluorocarbon / PTFECadmium + Fluorocarbon /PTFEZinc Nickel + Fluorocarbon /PTFEZinc Plating + Xylan 1424 BlueXylar 2 + Xylan 1070 BlueXylar 2 + xylar 101 coated stud bolt8.How to order the fluorocarbon coated stud bolts?Example#1,Stud Bolt 5/8″x80mm + 2 Heavy Hex Nuts ASME B18.2.1/B18.2.2/B1.1 Cl.2A/2B ASTM A 193 Gr.B7 - A 194 Gr.2H Fluorocarbon Coated blue colorStud Bolts B7 c/ w 2Nuts 2H Fluoro Carbon Coated ASTM A 193 Gr.B7 - A194 - Gr.2HStud Bolts B7 c/ w 2Nuts 2H Black ASTM A 193 Gr.B7 - A194 - Gr.2H
