SEI Corrosion ProofTM Rust Converter
The SEI Corrosion Proof Rust Converter utilizes CPTTM Technology (Corrosion Preventative Technology). This is a highly charged and durable migrational molecule that has the ability to penetrate and travel through a wide variety of mediums in order to find and bond with all types of metal. The CPT molecule needs to fulfill its ionic attraction by bonding with either ferrous or non-ferrous metal. Once the CPT molecule has found metal it creates a highly durable, resilient and robust chemical bond. This bond provides extensive protection for long periods of time in very harsh environments. The SEI Corrosion Proof Rust Converter is a water-based primer recommended for application to rusty or poorly prepared steel surfaces where further corrosion protection is required and good surface preparation is difficult to achieve. SEI Corrosion Proof Rust Converter is formulated to penetrate rust, eliminate rust, penetrate to the bare metal and stop further rusting. SEI Corrosion Proof Rust Converter allows the CPT molecule to penetrate and modify the surface rust into a hydrophobic passive layer. SEI Corrosion Proof Rust Converter combines the above-mentioned technology with a high solids waterborne moisture displacing resin with extremely low water vapor permeability. SEI Corrosion Proof Rust Converter does not contain tannic, phosphoric acids or any heavy metals and is a low VOC and environmentally friendly product. Furthermore, it provides extensive long-term corrosion protection for poorly prepared substrates, and can be top-coated with solvent-based and water-based paints with no bleeding what so ever.

Typical Application
SEI Corrosion Proof Rust Converter is recommended for use on all steel surfaces as a rust converter primer. The product can be used in situations where proper cleaning or sandblasting is difficult.
- Industrial maintenance
- General metal
- Marine
Application
It is recommended that any loose rust be removed with a wire brush and the rusty steel surface washed with high-pressure water to remove excess salt contamination. Brush, roll or spray SEI Corrosion Proof Rust Converter with no surface show-through at 3-5 mils (75-125 microns) wet film thickness. Brush or roll application is preferred to ensure penetration into the rust. The coating can be applied to dry or damp surfaces. A second coat of SEI Corrosion Proof Rust Converter should be applied within 20-30 minutes after the first application to ensure maximum protection. Allow to dry for 8-12 hours before applying the SEI Corrosion Proof Topcoat.
Limitations
- The resin system in the primer is not UV stable and changes color in outside conditions. This does not change converting or protection properties and does not affect the topcoat or topcoat adhesion.
- For proper application, the product should always be mixed thoroughly before use.
- On certain types of rust, various degrees of darkening may be visible, and may even be incomplete under certain drying conditions. The degree of darkening does not affect the coating; the primer will continue to convert rust. Upon drying, the formulation will exhibit excellent base corrosion preventative performance.
Packaging & Storage
SEI Corrosion Proof Rust Converter is available in 5-gallon plastic containers and 55-gallon metal drums. Keep product from freezing. The shelf life of the coating is one year.
