SEM 39673 Self Etching Primer Black 20 oz Aerosol

SEM 39673 Self Etching Primer is a professional automotive primer designed to provide excellent adhesion and corrosion resistance on properly prepared metal surfaces. Its quick-drying formula makes it an excellent choice for automotive refinishing, restoration, collision repair, and other metal preparation applications.

Excellent Adhesion and Corrosion Resistance

This self-etching primer is formulated to create a strong foundation on properly prepared metal. It provides excellent adhesion to steel, aluminum, and stainless steel while helping protect the surface against corrosion. Therefore, it is especially useful when preparing bare automotive metal for subsequent refinishing steps.

The black finish also provides a convenient base for many automotive refinishing applications. Because the product comes in a ready-to-use aerosol can, there is no need to prepare a spray gun for smaller repair areas or individual components.

Quick-Drying Automotive Primer

SEM 39673 features a quick-drying formulation that helps technicians move efficiently through the refinishing process. SEM recommends applying 2–3 light coats, allowing approximately 5–10 minutes of flash time between coats. The recommended topcoat time is approximately 10–20 minutes under the specified application conditions.

The aerosol application is particularly convenient for automotive restoration work, repair areas, replacement parts, and smaller metal components. It allows controlled application while providing the performance expected from a professional automotive refinishing product.

Ideal for Bare Metal Preparation

Proper surface preparation is important before applying any self-etching primer. The substrate should be properly cleaned and prepared according to the manufacturer’s instructions. Once prepared, the primer creates a suitable foundation for the next stages of the refinishing system.

Its combination of strong adhesion, corrosion resistance, fast drying, and convenient aerosol application makes it a practical choice for professional body shops as well as automotive restoration projects
