Overview
Built for the job.
A professional grade coating that reproduces the original look of cast-iron parts. Cast blast is perfect for water pumps, intake manifolds, master cylinders and more. It protects against rust, has a low sheen, and resists heat up to 250 deg F continuous.
Seymour® 16-048 Spray Paint is a high-performance, 16 fl-oz aerosol formulated for California Cast Blast finishes on e-coat and steel substrates. The single-component formula delivers a uniform matte coating ideal for automotive body panels requiring a durable, low-gloss appearance.
Technical advantages include a rapid cure time of 12 hours at ambient temperatures between 50 °F and 90 °F, allowing fast turnaround in a production environment. Each can provides up to 15 sq ft of coverage, reducing material waste and minimizing spray passes. The paint is compatible with e-coat and bare steel, ensuring strong adhesion without additional primers.
Due to its flammable nature (flash point -19 °C) and listed GHS hazards, use in a well-ventilated area with appropriate PPE-eye protection, gloves, protective clothing, and a respirator-is required. Follow the H-statements for handling and first-aid procedures as outlined in the SDS.
