Xylar 2 is the cornerstone of a generation of hard, cermet finishes. Almost twice as hard as the best organics, it offers a tough, sacrificial barrier to corrosion and wear. Xylar 2 is a porous ceramic coating that is extremely hard and, with respect to structural metals, is chemically sacrificial. Applied to ferrous, aluminum, or other metals, it is “sacrificed” to a corrosive medium before the substrate is attacked. The high temperature stability of Xylar 2 (1,200°F/650°C) makes it ideal for engine applications where the electrical couple between dissimilar metals could result in corrosion. Xylar 2 is used in abrasive applications such as furnace chutes, air ducts, grain handling equipment, and numerous vehicle-underbody components where abrasive wear or stone pecking is common.
The primary end use for this coating is: CORROSION RESISTANT PRIMER FOR MARINE ENVIRONMENTS

Parts must be free of dirt, oil and other soils to achieve good adhesion and defect-free coatings. The following are the recommended substrates and substrate preparations used with this coating
|SUBSTRATES||COLD ROLLED STEEL, ALUMINUM|
|SUBSTRATE PREP||DEGREASE AND GRIT BLAST - USE 60-80 MESH ALUMINUM OXIDE MEDIA FOR GRIT BLAST.|
|PRIMERS / BASECOATS||N/A|
Mix containers thoroughly by shaking or stirring until any solid material on the bottom has been eliminated. Best results are obtained when the coating temperature is 65-90°F (18-32°C). Adjust viscosity, if necessary, using the recommended thinner and an accurate Zahn Viscosity Cup. Other viscosity cups may also be used. Add thinner in increments of 2% until proper viscosity is achieved. Low viscosity produces runs and sags and low film thickness. High viscosity produces poor sprayability and uneven appearance. Any dried coating or dirt may be removed by passing the coating through a 100-200 micron filter.
|APPLICATION VISCOSITY||AS SUPPLIED - REDUCTION NOT RECOMMENDED|
|VISCOSITY ADJUSTMENT||D.I. WATER, OR WHITFORD SOLVENT 101 IF NECESSARY|
|OTHER INFORMATION||NOTE: WATER WASTE WILL CONTAIN CHROMIUM - MUST DISPOSE OF PROPERLY|
This product is designed primarily for spray application. Consult with a Whitford representative if other types of application are being considered. Use an air spray gun with a siphon cup or pressure pot. Select a fluid nozzle and air cap that meet application needs. The Whitford Laboratory uses a Binks Model 2001 gun with a #66S fluid nozzle and a #66SD air cap. The air supply line must be equipped with traps to remove water and oil. Drain and service traps frequently. Apply the dry film thickness as specified. 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.
|DRY FILM THICKNESS||O.8 - 1.2 MILS (20 - 30 MICRONS)|
|CLEAN UP SOLVENT||WATER|
In order to completely cure the coating, the SUBSTRATE TEMPERATURE must remain at the specified temperature for the entire bake schedule
|FLASH OR AIR DRY||AMBIENT TO 150°F (66°C) UNTIL PART TURNS COMPLETELY GREY IN COLOR.|
|BAKE SCHEDULE||5 - 10 MINUTES AT 750 - 650°F, 20 MINUTE AT 550 - 600°F|
Evaluate the coating according to the following specifications
|PENCIL HARDNESS||8H||GLOSS: MATTE AS SPRAYED|
|CURE TEST||WHITFORD TM-115C / APPLY 1 DROP OF HOT TAP WATER TO PART LET STAND 1 MINUTE, BLOT WITH PAPER TOWEL = NO DISCOLORATION ON TOWEL.|
