Overview
Built for the job.
Bumper coater aerosols are a line of advanced coatings formulated to restore the OEM finish on automotive bumpers and plastic cladding.
SEM Bumper Coater® 39183 is a medium-gray aerosol trim paint formulated for rapid finish work on OEM plastic bumpers and other exterior trim components. The 16 oz can delivers consistent color and gloss in a single-stage application, making it ideal for body shop technicians who need efficient touch-up or full-coat coverage.
Key performance data include a flash time of 5-10 minutes between coats and an effective coverage of approximately 10 sq ft per can at 1 mil dry film thickness. The formulation is compatible with OEM plastics, primed substrates, and standard automotive primers, providing reliable adhesion without additional surfacing steps. VOC content is 701 g/L.
Due to its flammable aerosol propellant and hazardous constituents, the product must be applied in a well-ventilated area while wearing eye protection, gloves, protective clothing, and a respirator as specified on the SDS. Follow all H-statements (H222, H280, H304, H315, H336, H351, H361, H373) for safe handling.
