Corroseal® Rust Converting Primer

Product Data Sheet
DescriptionCorroseal® is a water based rust converter combined with a non pigmented high quality latex metal primer. The converter segments turn rust into a barrier layer of black non rusting magnetite. The primer acts as a bonding agent for oil-based intermediate and finish coatings of epoxy, enamel, acrylic, polyurethane and moisture-cured urethane, and with water based coatings not subject to tannin staining. Water based coatings may require an oil based stain blocker as an intermediate application. Corroseal® is non flammable and non corrosive.

Do not apply onto zinc chromate or phosphates, lead, magnesium, copper powder, graphite, borate pigments.

Prep & Prime
Remove all salt, loose rust, mill scale, dirt, grease, oil, old paint and other deposits. Apply non-solvent cleaner according to manufacturer's directions and rinse. A residue free surface is essential before coating application begins. The surface should be a CLEAN, TIGHT RUST.
Application
Brush, roll or spray undiluted Corroseal® in a heavy white coat with no surface show through at 8-10 mils wet film thickness. When black color appears, rust conversion has started. Wait at least 24 hours before top coating. A second coat of Corroseal® may be applied while first coat is still tacky. Apply all topcoats according to manufacturer’s specifications. Use oil based marine or industrial coatings for best weather protection. Use a separate container for application so you don't contaminate your original base product.
CoatsWaterbourne topcoats subject to tannin staining must be tested 48-60 hours before use. If tannin occurs, apply an oil based stain blocker or topcoat. Always prepare a test patch to ensure compatibility with substrate and subsequent products.
