PRODUCT DATA SHEET PAGE: 1 of 3PRINT DATE 28/01/20061. GENERAL INFORMATION.

Product name: Xylar

Product code: ---1 - F1085Recommended use: Aqueous / acidic based aluminium "cermet" coating. Excellent chemical,

corrosion and abrasion resistance at extreme temperatures.Typical applications: Xylar coatings provide the aircraft, aerospace and marine industries with

materials to protect components from high temperature oxidation, salt ladenatmospheres, chemicals and abrasives. Xylar 101 in conjunction with Xylar 1meets the USA Military Specification MIL-C-81751B "Coating, Metallic-Ceramic." It enhances the system's performance by retarding the rate of sacrificialanodic protection afforded by Xyar 1.

5. RECOMMENDED APPLICATION TECHNIQUE.

Application equipment / technique: This material is designed primarily for spray application. Contact our technicalservice department if other types of application are being considered. Thiscoating is applied in our laboratories using a Binks Bullows 630 spray gunequipped with a 071 (1.8 mm) material nozzle, a 66SD1 air cap and a stainlesssteel needle. The air supply should be equipped with air and moisture trapswhich are drained / serviced regularly.The proper amount of coating should be achieved with two or three passes of thespray gun across the work piece. Apply the coating to a uniform, full wetappearance.

Recommended dry film thickness /coat:

Approximately 20 5 microns (typical wet film thickness 60 15 microns).

Number of coats recommended: Typically 2 or more. Will recoat, cure between coats if applying multiple coats.After cure of the last coat burnish with aluminium oxide at a low air pressure 20 -30 psi (1.4 - 2.1 kgf/cm2) to improve the appearance, abrasion and corrosionresistance.Determine if the burnishing is complete by using an ohmeter. The burnishedsurface should have less than 1 ohm resistance at any two points on surface. Ifsurface is not conductive continue burnishing until it is.

Clean-up solvent: Water.

6. FLASH OFF AND CURE SCHEDULE.

Please note that oven temperatures can be very different to substrate temperatures and the following temperaturesapply to PEAK SUBSTRATE TEMPERATURE .Flash-off conditions: 5 minutes at 80 - 100C [176 - 212F]Optimum cure schedule: 30 minutes at 343C [650F].Minimum cure temperature: 30 minutes at 343C [650F]Maximum cure temperature: 15 minutes at 400C [752F]

7. WHITFORD QUALITY CONTROL TEST METHODS.

Evaluate the cured coating according to the following specifications:Test. Test method number.Specification.Dry film thickness 114A >40 microns.Pencil hardness (room temperature) 131A >3HAdhesion, crosshatch and sellotape 132C No loss of adhesion.

8. SHELF LIFE, STORAGE AND HANDLING.

Handling: Avoid contact with skin, eyes and clothing. Wear personal protective equipment.Wash hands before breaks and immediately after handling the product. Removeand wash contaminated clothing before re-use.

Storage: Keep containers tightly closed in a cool, well-ventilated place. Store in originalcontainer. Keep at temperatures between 5 and 30C. Freezing will affect thephysical condition but will not damage the material. Thaw and mix before using.

Shelf life: 6 months. This material settles rapidly during storage. High speed/shear mix thematerial(s) every month to maintain quality / Turn the containers upside downevery month to minimise settling.

Further information: Refer also to instructions for use. Data sheets more than 24 months old may notbe reliable: obtain an up-to-date version to be sure of the information.
