Corroseal® Technical Data
Product Description
Corroseal® 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 metal 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.
Basic Use
Corroseal® is recommended for use on rusted or partially rusted steel surfaces as a rust
converter / metal primer, and as an etch primer on aged tight paint of any color, and as a sealer on non ferrous
metals such as some aluminum, copper, and brass.
- Protects against future rusting
- Can be used on welds
- Eliminates need to mechanically blast to white metal in many instances
- Not recommended for outside hull underwater applications
