Xylan 1424 Coated Fasteners

Stud Bolts, Nuts, Screws, Threaded Rod & Washers

Xylan 1424 is a premium high technology fluoropolymer coating system that has been engineered to provide exceptional corrosion protection. The system was developed to meet the demand for improved protection in marine environments and provides a hard, durable uniform, low friction coating which is capable of continuous operation at temperature extremes. Xylan 1424 is readily identifiable through its distinct blue colour. Xylan 1424 coated fasteners demonstrates exceptional adhesion and resists galling, blistering and chipping and will not crack or peel. Xylan 1424 coated bolts extremely versatile. They can with stand wide fluctuations in temperature (from -40°Cto+175°C) and can be applied to a wide variety of substrates. Xylan 1424 Coated Fasteners are a cost effective solution by its ability to increase part life, reduce maintenance costs and improve productivity. Xylan 1424 Coating outperforms other finishes, including zinc/chromate, galvanising and cadmium plating. Furthermore, the application process does not require the use of pickling or plating solutions thus eliminating the danger of hydrogen embrittlement which can weaken the metal substrate. As Xylan 1424 is waterborne it does not suffer from the environmental pollution problems associated with coatings containing cadmium, chromium and other toxic substances.
Xylan 1424 fasteners are used extensively at petrochemical drilling sites, processing plants and water works industry to protect them from the effects of sub-sea and splash zone exposure, and the corrosives associated with processing petrochemical products. In addition, the uniform, low coefficient of friction of the coating reduces ‘make-up’ and ‘break-out’ torque, ensuring that installation and subsequent removal of components is much simplified. These inherent ‘anti-seize’ properties are particularly important in isolated, fire hazard or confined spaces, as are often found in the petrochemical industry.

Xylan 1424 Substrate information

Xylan 1424 coated Fastners provide excellent adhesion to a variety of substrates, yet require a minimum of surface preparation.Final product quality and performance depends on careful substrate preparation. Contaminated substrates may cause poor adhesion or defects in the final dry film. Each Fastener like bolt, stud, nut, washer to be coated must be free of all contaminants e.g. oil, grease, detergent, rust and blast media.
Most applications require only a solvent wipe or vapor degreasing of the substrate to remove surface contaminants. Some applications may require additional surface preparation in order to enhance adhesion (such as grit blasting with aluminum oxide). Substrate preparation should be based on the design requirements of the item.The following are the recommended substrates and substrate preparation used with this coating
Xylan 1424 coating can be applied to many types of substrate material such as aluminum, brass, high alloy steels, carbon steel, stainless steel, titanium and zinc plating. Final product quality and performance depends on careful substrate preparation. Contaminated substrates may cause poor adhesion of the coatings or defects in the final dry film. Each item to be coated must be free of all contaminants, e.g. oil, grease, detergent, rust and blast media. Substrate preparation should be based on the design requirements of the part. If you are unsure which process is best suited to your needs please contact our technical service department. The following are the recommended substrates and substrate preparation used with this coating.

Substrates	Aluminium / Mild steel / Stainless steel / Some plated metals.
Substrate preparation	Degrease and gritblast. An Ra (mean roughness) of 2.5 ± 1 microns, measured using surface roughness measuring equipment is recommended. This can typically be obtained using 80 - 100 mesh (150-200 micron) iron free, aluminium oxide grit at 80 psi (5.6 kgf/cm 2 ). However since the Ra value achieved depends on the actual substrate, initial trials are recommended to establish the optimum grit size and air pressure for each substrate type. A heavyweight zinc phosphate, class 1B is recommended on mild steel.
Primer	Not required but Xylar 1 / Xylar 2 / can be used to improve overall performance.

Xylan 1424 Coated Fasteners Preparation for Application

Mix the coating by shaking the container or stirring the contents until any settling has been eliminated. It is imperative that the coating material be adequately dispersed.
The viscosity of Xylan 1424 coating is generally suitable for application as supplied. However, some viscosity adjustment may be necessary depending upon the type of equipment employed.

Mixing prior to use	It is imperative that the material is adequately mixed before use. The material should be high speed / shear mixed before use to eliminate any settling. Avoid creating foam while mixing. This product is liable to "skin." Keep container tightly closed when not in use. If container needs to be open to the air ensure product is continuously, slowly mixed.
Recommended application viscosity	This material is generally suitable for application as supplied.
Viscosity adjustment / thinning	Optimum results are obtained when the material is at "room temperature" nominally 15 - 30°C. If absolutely necessary adjust viscosity with Whiford solvent 54 or water. Add thinner in 2% increments until the desired application characteristics are obtained. Take care not to add too much thinner as low viscosity may produce rapid settling, runs and sags or low film thicknesses.
Filtering	This material is sieved before dispatch from our factory but as an added precaution we recommend that you filter it through a 75 - 150 mesh (100 - 200 micron) sieve prior to use.

Xylan 1424 Recommended Application Technique

Xylan 1424 coatings are applied by conventional air spray techniques. Any spray gun apparatus associated with the application of fluoropolymer coatings will provide a uniform film without difficulty. Other methods of application, which have been successfully utilized, include airless, HVLP and electrostatic units (air and disk)

Application equipment / technique	This material is designed primarily for spray application. Contact our technical service department if other types of application are being considered. This coating is applied in our laboratories using a Binks Bullows 630 spray gun equipped with a 071(1.8mm) material nozzle, a 66SD1 air cap and a stainless steel needle. The air supply should be equipped with air and moisture traps which are drained / serviced regularly.
Recommended dry film thickness / coat	17.5 ± 2.5 microns (typical wet film thickness 50 ± 7.5 microns).
Number of coats recommended	1 or more. Will recoat, cure between coats if applying multiple coats.
Clean-up solvent	Water, Methyl ethyl ketone on dried residue.

Xylan 1424 Flash Off & Cure Schedule

Xylan 1424 Coated Fasteners may be cured immediately or be accumulated for a batch oven. Whitford recommends a cure of 10 minutes at 450°F (230°C) for Xylan 1424 coated bolts nuts and washers. Other time/temperature relationships may be used (see graph). Optimum dry film characteristics are obtained when the coating is cured per our recommendations. Temperature means part metal temperature (PMT), not oven temperature. add graph photo from xylan all coating
