75-9422	ALUMINUM HEAT RESISTING PAINT

GENERAL DESCRIPTION Pruett-Schaffer’s #75-9422 Aluminum Heat Resisting Paint is a single package, aluminum pigmented coating made with modified silicone resin. When properly heat cured, it will provide economical protection against corrosion of ferrous metals in moderate to high temperature environments. RECOMMENDED USES This product is recommended as an interior or exterior topcoat where a corrosion-resistant coating is needed for ferrous metals exposed to: 1. continuous, non-cycling temperatures between 450-800 ^0F; 2. non-routine, short-term excursions to temperatures up to 1200 ^0F; 3. where thermal shock due to rapid service temperature variations will NOT be encountered. This coating has very good salt resistance, but is not recommended for continuous water immersion service, or for exposures involving mineral acids, alkalis, or oxidizing agents. SURFACE PREPARATION All surfaces to be coated must be clean, dry, free of mill scale, oil and grease, rust, paint, weld spatter, burning slag, dust, and chalk. Substrates should be degreased and blasted to SSPC-SP-5 (white metal blast cleaning), with a profile of < 0.2 mil; all mill scale must be removed or in-service failure due to mill scale disbondment will occur. On steel completely free of mill scale, SSPC-SP-3 Power Tool Cleaning may be used; but high temperature testing on an individual	case basis is strongly recommended. THINNING Under normal conditions no thinning is necessary. If desired, thin with xylol or toluol. Add a little at a time with constant gentle agitation to a maximum of 5% by volume. APPLICATION EQUIPMENT May be applied by brush, air-assisted or airless spray equipment. Airless spray gives the best results, use .015-.020 inch tip size. Brushes should be of polyester or nylon construction. APPLICATION INSTRUCTIONS Apply evenly to 4-5 mils wet film thickness, which will yield a 0.7-0.85 mil dry film. Avoid heavy overlap and do not exceed 5 mils wet film thickness, or high temperature resistance will be reduced. Do not apply when substrate temperature is within 5 ^0F of the dew point or greater than 140 ^0F. Keep the film dry until heat curing is finished, do not paint outside late in the day when condensing conditions are expected. AIR DRYING AND HEAT CURE Dries tack free in 1 hour at 77 ^0F, dries to light handling in 2-4 hours. This coating must be heat cured following application, or it will not develop the desired high temperature resistance. Keep the film dry until heat curing is finished. Allow to air dry to a tack free state, then cure within 24 hours of application by heating to 450 ^0F for a minimum of 1 hour. Heat curing must be	performed, or reduced service life will result. If the coating is being placed into high temperature service within 24 hours, heat curing may be omitted but increase the temperature of the unit gradually (100-200 ^0F per hour) when initiating service. CLEANUP Clean equipment with xylol or toluol before the film dries.
