Product Description

The acid-etch chemistry chemically bonds to bare steel, aluminum, and galvanized metal substrates — providing molecular-level adhesion that mechanical bite alone cannot match. No separate metal conditioner or conversion coating step required: SEM Self-Etching Primer treats, conditions, and primes the metal surface in a single application.
Aerosol format delivers ready-to-spray convenience for spot repairs, weld zones, and bare metal touchup without gun setup or cleaning — the fastest way to prime small bare metal areas in production repair workflows. Green-colored formula an alternative to gray/black for specific OEM color-match requirements. Compatible with waterborne and solvent-borne topcoat systems.
