Seymour MRO 620-1407 Industrial Primer is a red-oxide aerosol primer designed for high-performance corrosion protection on e-coat and pre-primed substrates in body shop environments. Delivered in a 20 fl-oz can, it provides approximately 18 sq ft of coverage per container when applied under recommended conditions.
Key technical benefits include a rapid recoat window of 20 minutes, allowing multiple layers to be built efficiently. The formulation remains stable across an application temperature range of 50-90 °F and retains heat-resistant properties typical of industrial primers. With a guaranteed two-year shelf life, the product offers consistent performance for long-term inventory.
Due to its classification as a flammable aerosol with acute health hazards (aquatic toxicity, carcinogen, skin corrosion, eye damage), proper personal protective equipment is mandatory: safety glasses or face shield, chemical-resistant gloves, flame-retardant clothing, and an appropriate respirator. Use in a well-ventilated area and observe all H-statements on the label.
