The products are based on lead- and chromate free pigments.RECOMMENDED USESRUST-OLEUM Hard Hat 7715 and 7778 should be used on new, bare steel, blasted steel orlight rusted steel surfaces or properly prepared painted substrates alike barbecue grills, fireplace equipment, space heaters etc.RUST-OLEUM Hard Hat 7715 and 7778 are intended for small maintenance jobs or for touchup. RUST-OLEUM Hard Hat 7715 and 7778 provide heat resistance up to 750°C (= 1380°F)dry heat (short term peak resistance) in sheltered or interior environments.TECHNICAL DATAAppearance: Satin glossColour: 7715 Aluminium / 7778 BlackPropellant: Dimethyl etherRecommended film thickness: 25 µm dry, equals 100 µm wetVOC-content: 7715: 650 g/l / 7778: 640 g/lDrying times 20°C/50% r.h.To touch: 1 hourTo handle: 3 hoursTo recoat: Within hour or after 48 hoursFull hardness 24 hours after minimum service temperature of 150°C has been reachedGradually heat the coating to 150°C (max. 50°C/hour).Heat resistance: Standard 600°C (dry heat)Short term peak resistance 750°C (dry heat)CoverageTheoretical: 2 m² per spray can at 25 µm dryPractical: Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application.SURFACE PREPARATIONRemove dirt, grease, oil, loose rust and all other surface contaminants by appropriate means.Sand intact coatings to roughen the surface slightly. The surface must be clean and dry during application.DIRECTION FOR USERemove cover cap. Shake vigorously for at least one minute after the rattle of mixing ball isheard. Shake frequently during use.Hold can approx. 30 cm from surface. Use back and forth motion keeping can parallel withsurface. Ensure that can is in motion when spray button is pressed to avoid runs and sags.Apply several thin layers at a few minutes interval to achieve adequate coating thickness.After use turn can upside down and press spray button for 2 - 3 seconds to clean valve.APPLICATION CONDITIONSFor optimum results the relative humidity shall be below 85% and the temperature of the canabove 0°C. REMARKSRUST-OLEUM Hard Hat 7715 and 7778 are self-priming and should not be applied onprimers or coatings, which are not heat resistant.SAFETYConsult Safety Data Sheet and Safety Information printed on the can.SHELLIFE / STORAGE CONDITIONS3 years from date of production in unopened cans, if stored in dry, well ventilated areas, not indirect sunlight at temperatures between 5° and 35°C.
