STEEL-IT Polyurethane Topcoat For Automotive and Motorsports Applications
STEEL-IT Polyurethane Topcoat is the preferred coating for automotive and motorsports applications for its anti-corrosive performance, abrasion-resistance, UV/weathering-resistance, salt-resistance, and the ability to weld directly on the coating, without having to remove the coating first to repair cracks or fissures in the part underneath.
Racing teams choose STEEL-IT Polyurethane to protect the metal parts on their race vehicles (chassis, roll cages, suspensions, axels, brackets, arms, bumpers, undercarriages) that take a beating as they race on some of the world’s most punishing race courses in the harshest climates. Even after thousands of miles and significant abrasion from rocks, sand, salt, and debris at high speeds, many racing teams have found that STEEL-IT requires significantly less touching-up than any other product available (including powder-coating) and that STEEL-IT is much easier to touch-up when they need to do so.
STEEL-IT Polyurethane is available in two colors: STEEL-IT 1002 Steel Gray Polyurethane Topcoat and STEEL-IT 1012 Black Polyurethane Topcoat. STEEL-IT 1002 Steel Gray Polyurethane is a metallic gray color resembling raw steel with a matte finish. STEEL 1012 Black has a satin finish.
The topcoat is available in a liquid form (quarts and gallons), which is applied with conventional spray gun equipment, as well as 14oz aerosol spray cans. The decision to use the aerosol versus the liquid topcoat is influenced in many cases by the shape and size of the job in question, as purchasing the liquid form would be more cost efficient for applications with a larger coverage area. Some teams use only the aerosol cans to coat their parts; they feel they have greater control over where the coating lands compared to using liquid STEEL-IT Polyurethane supplied in quarts or gallons, and experience less overspray when coating tubular parts like the chassis or roll cage. Other teams prefer using conventional spray equipment, and some use a combination of the aerosol and spray equipment depending on the part they’re coating.
For automotive applications, STEEL-IT Polyurethane Topcoat is used alone without any primer to maintain direct-weldability and at least two coats are applied directly to the prepared bare metal after profiling for mechanical adhesion (via sand-blasting or power-sanding).
