75-13155	FLAT BLACK HEAT RESISTING PAINT

GENERAL DESCRIPTION Pruett-Schaffer’s #75-13155 Black Heat Resisting Paint is a single package, heat curing coating made with 100% silicone resin. When properly heat cured, it will provide superior protection against corrosion of ferrous metals in extremely high temperature environments. RECOMMENDED USES This product is recommended as an interior or exterior topcoat where a premium corrosion-resistant coating is needed for ferrous metals exposed to: 1. continuous temperatures up to 800 ^0F, wet or dry; 2. intermittently or continuously cycling temperatures in the range of 450 to 800 ^0F, wet or dry; 3. thermal shock due to rapid service temperature variations, rainfall, or steam. It 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. This product must then be applied immediately. For service temperatures below 750 ^0F, a heat resisting inorganic zinc primer, such	as Pruett-Schaffer’s #99-12886 or equivalent, may be used to increase corrosion resistance. 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 1-2 mils wet film thickness, which will yield a 0.3-0.6. mil dry film. Avoid heavy overlap and do not exceed 5 mils wet film thickness (1.5 mils dry film), 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 TIME Dries tack free in 1 hour at 77 ^0F, dries to light handling in 4-6 hours. This coating should be heat cured following application, or it will not develop the desired maximum high temperature resistance. Keep the film dry until heat curing is finished.	HEAT CURING 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. CLEANUP Clean equipment with xylol or toluol before the film dries. ENVIRONMENTAL This product contains no chromate, and complies with current federal regulations regarding the use of lead in paint.
