29-50	WHITE WATERBASED LATEX STRIPPABLE COATING

GENERAL DESCRIPTION Pruett-Schaffer’s #29-50 White Paint is an air-drying, water based emulsion paint. It is designed as a temporary spray applied, membrane-coating system. It offers a cost-effective alternative to other more expensive methods of removing overspray from spray booths, lights and walls. Strippable coating acts as a barrier between the wet paint overspray and the clean metal spray booth surface, which should be easily removed in large sheets during booth maintenance. This coating allows high film build without sags and good reflectance properties for better visibility. It exhibits all of the desirable properties of standard water based products such as low VOC, toxicity and odor with non-flammability and soap and water cleanup. RECOMMENDED USES This product is recommended for new installation over metal, or cleaned smooth surfaces. Dried paint, dirt and overspray buildup increase surface profile and porosity which will cause the strippable coating to come off in smaller pieces rather than large sheets! CLEANUP Clean equipment with warm soap and water before the film dries.	DRYING TIME Dry time will depend on substrate temperature, relative humidity, wind and solar conditions, and film thickness. A 5-6 mil-wet film will cure in approximately 30-40 minutes at 77 deg F. and 50% relative humidity. A 5 mil wet film will dry down to a 2.5 mil thick film (the minimum recommended film thickness) with enough strength to not break apart when pulled. Thicker films will provide better cohesive strength allowing easier strippability. SURFACE PREPARATION At a minimum for acceptable performance, all surfaces to be coated must be mechanically sound and free of oil/grease, loose rust/paint and overspray buildup. The smoother the surface the better the strippability. THINNING Under normal conditions no thinning is necessary or desirable. Thin if necessary with water only do not use organic solvents or oils. Add water a little at a time with constant gentle agitation to a maximum of 5% by volume. ENVIRONMENTAL This product meets current air pollution regulations regarding hydrocarbon and ozone reactive emissions. It contains no lead, chromate, or zinc.	APPLICATION EQUIPMENT May be applied by airless or conventional spray. Airless spray gives the best results, and is highly recommended for large jobs. Use a 30: 1 ratio drum or pail pump with a 3-4 gallon per minute capacity, a hydraulic metal braid hose with a working pressure of 2500 psi, and a .018-. 021 inch. For conventional use a pressure tank, fluid pressure 20psi, and atomizing pressure of 40-50 psi. APPLICATION INSTRUCTIONS Note: do not apply when air or substrate temperature is below 50 deg. F. or at least 5 deg. F above the dew point. Do not agitate during application. Vigorous agitation will cause bubbling & can reduce the viscosity of the coating causing excessive sags. Increase fluid pressure of spray rather than adding water if having difficulties spraying. PHYSICAL PARAMETERS VOC, ASTM D-3960: .71 lb./gal WEIGHT PER GALLON, ASTM D-1475: 10.73 lbs.
