COATINGSPRO STEEL SURFACES 2019 11 contaminants," he said. "ey may just start blasting without doing some sort of cleaning or testing for that, and it's going to compromise the long-term life cycle for any applied coating." Whether the job is on the interior or exterior of an asset can make a big difference, too. "e need to have a cleaner substrate and maybe a greater profile depth on the interior is more critical than the exterior because you're probably storing some type of commodity in it," said Sherwin-Williams' Morris. "And in today's world, we're applying heavier film thicknesses on the interior to increase the lifespan. On the outside, it's commonly your traditional three-coat system — zinc, epoxy, and urethane — and those systems are typically much thinner than your interior lining. A greater profile depth on a thinner coating system could actually be detrimental, because you may not cover the profile and then you get pinpoint rusting. Or the coating is very thin on it, and you're compromising service life due to degradation." Blasting Media In establishing the steel substrate's profile, a related factor can be the selection of blast media to be used in tandem with blasting equipment. " Typically, for your more angular blast profile, you're looking at the harder blast medias," said Sherwin-Williams' Morris. "Very few places allow the use of silica sand. So a lot of people have gone to coal slag or natural blast media. Or it could still be steel grit, aluminum oxide, garnet, you name it." According to U.S. Minerals, which provides many blast media options, factors to consider when choosing a proper media for blasting steel substrate include what material is being removed (e.g., rust, mill scale, paint, coating, etc.), the desired surface finish and profile, the budget/cost of the blasting media, and the availability of supply. While coal slag has been the primary product in many markets, such as bridges, water towers, and ships, U.S. VENDOR TEAM 3M Safety equipment manufacturer 2501 Hudson Rd.
