Product Description
SEM 39674 Self-Etching Primer, Black () is a professional acid-etch primer for bare metal preparation in automotive collision repair. 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.
Quart size for spray gun application on medium repairs and production use. Black-colored formula designed for application under dark topcoats and on inner structural panels. Compatible with waterborne and solvent-borne topcoat systems.
