Don't remove rust, convert rust!
Choose Corroseal® Rust Converter
Not all rust converters perform equally. Corroseal® Rust Converting Primer was
formulated specifically for use in the marine industry - one of the harshest environments for coatings.
There are considerable differences in formulas and performance between the various rust treatment
products in the market. Corroseal® has proven performance for over 25 years
in harsh environments, which is not true for many competing rust converter type products.
Comparing rust converters, rust encapsulators, or acid treatments.
It's important to remember that rust never sleeps!
Rust converters chemically treat the rust - converting it into an inert compound - which then acts as a barrier
layer against future rusting. Therefore when using a rust converter, especially Corroseal®, you
are adding a double layer of protection against future rusting before you even topcoat.
Rust encapsulators & inhibitors encase existing surface rust, cutting off the oxygen supply that keeps that
rust from growing. However, the existing rust is still there lurking under the encapsulating film, ready to continue
growing upon any surface damage to the paint film or film failure.
Acids used for treating rust are by nature corrosive, and any unreacted acid residue will remain on the surface.
This residue frequently interferes with the proper bonding of topcoats and can cause accelerated chalking.
Acids, such as phosphoric acid, do work well to remove rust stains from painted surfaces, but are not as effective
as rust converters on a rusted surface.
Corroseal® Converts Rust
Corroseal® is a water based rust converter combined with an unpigmented high quality copolymer latex metal primer.
The advantages of using Corroseal® include reduced labor costs by not having to mechanically or chemically remove
existing rust while at sea, on bridges, or in operational factories; and by the environmentally friendly properties
of the product which makes delivery, storage, use, cleanup and disposal relatively convenient when compared to
other metal primers and rust removal methods.
Corroseal® is non flammable, non corrosive, easy to apply, and cleans up with just soap and water
Corroseal® works equally well applied by an inexperienced homeowner or by a professional shipyard painter.
Corroseal® Protects
Corroseal® converter chemistry is a proprietary technology based on very mild acids combined with an unpigmented,
improved metal primer, a copolymer created from styrene butadiene (latex) chemistry.
Corroseal® is designed to apply directly to clean tight rust. The first bloom of rust after waterblasting is
a benefit.
The effects of Corroseal
® are created by its two principal components:
- Mild acids to arrest rusting and convert existing rust to other compounds
- A chemically advanced copolymer that bonds with both the converted rust and with applied topcoats.
Corrosion (rust) is simply metallurgy in reverse - meaning that it's nature's way of returning steel back to its
original ore forms. The process of corrosion in the field (outside the laboratory) does not occur in a nice uniform
growth, and the actual formation of rust is a very complex 5 step process. You can
learn about rust and how it works here.
Additionally all commercial steel contains impurities, which are not uniformly distributed in the metal.
Understanding the chemistry of corrosion and effectively dealing with many of the irregularities that are
present on a particular steel surface is what makes Corroseal® Rust Converting Primer better than
other formulas.
Corroseal® is Paintable
Corroseal® remains "open" to mechanical, chemical and electrical bonding with most topcoats for 30 days.
Corroseal® is well known as a high quality and consistent product by those who routinely deal with the painting
rusted metal. Corroseal® serves as the primer and bonds with oil based paint, epoxy, urethane and most other top coats.
