Overview
Built for the job.
A durable, zinc enhanced coating that protects all metal surfaces. Electrochemical galvanic action keeps on protecting even if scratched. Dry film is 86% pigment which results in less smoke and electrode wear when welding, and cuts faster than 100% zinc rich coatings. Stops rust creepage.
Seymour PBE 20-1675 Weld-Thru Primer is a gray, low-VOC (59%) aerosol primer designed for rapid weld-through protection on newly fabricated panels and repaired sections. It provides a seamless barrier that seals the substrate before welding or spot-repair processes.
One 20 oz can delivers up to 18 sq-ft of coverage when applied at 50-90 °F, allowing efficient use on small to medium repair zones. The primer adheres directly to e-coat and existing primer layers, creating a durable film that resists flash rust and prepares the surface for subsequent topcoats. Shelf life is guaranteed for two years under proper storage conditions.
Due to its flammable nature (flash point -19 °C) and classified hazards-including aquatic toxicity, carcinogenicity, eye damage, and organ toxicity-use requires a respirator, eye protection, gloves, and protective clothing in a well-ventilated area. Follow H-statements H222, H280, H319, H336, H351, and H373 for safe handling.
