xylan 1070 coated fasteners
xylan 1070 coated fasteners
Xylan 1070 coated fasteners contains corrosion inhibitors for better corrosion resistance. It excels in applications requiring a dry film lubricant effective against a broad spectrum of chemicals and corrosives.Xylan 1070 coated fasteners demonstrate excellent adhesion to a variety of materials. Simple test procedures will determine if Xylan coatings will bond to a new or untried substrate material.
Organic solvent based, low friction coating for studbolts. Normally used over a phosphate or other pretreatment to achieve up to 3000 hours salt spray resistance.
Xylan 1070 widely used in Aerospace and marine industry components. Thermal barrier for automotive engine and exhaust components

Xylan 1070 Substrate Preparation
Xylan 1070 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.
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 | Most common metals. |
|---|---|
| Substrate preparation | Degrease, gritblast and additional pre-treatment. An Ra (mean roughness) of 2.5 ± 1.0 microns, measured using surface roughness measuring equipment is recommended. This can typically be obtained using 60 – 80 mesh (200 – 250 micron) iron free, aluminium oxide grit at 80 psi (5.5 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 | A heavyweight zinc phosphate, class 1B is recommended on mild steel and 15 – 20 microns of Xylan 4090 is recommended. Warming the item to 40°C may facilitate application of the coating. |
Xylan 1070 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 1070 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. |
|---|---|
| Recommended application viscosity | 40 – 60 seconds in a BS 4 viscosity cup. Optimum results are obtained when the material is at “room temperature” nominally 15 – 30°C. |
| Viscosity adjustment / thinning | This material is generally suitable for application as supplied. If absolutely necessary adjust viscosity with Whitford solvent 93. 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 100 mesh (150 micron) sieve prior to use. |
Xylan 1070 Recommended Application Technique
Xylan 1070 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 (1.8 mm) 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. <br>The proper amount of coating should be achieved with two or three passes of the spray gun across the work piece. Apply the coating to a uniform, full wet appearance. |
|---|---|
| Recommended dry film thickness / coat | Approximately 20 ± 5 microns (typical wet film thickness 100 ± 25 microns). |
| Substrate temperature | <45°C |
| Number of coats recommended | 1 or more. Will recoat, flash off between coats if applying multiple |
| Clean-up solvent | Whitford solvent 91. |
