CPT-298 Rust Converter Primer

CPT-298 is a corrosion converting and corrosion preventing high build primer. CPT-298 is recommended for application to corroded or poorly prepared ferrous or non-ferrous surfaces where further corrosion prevention is required and good surface preparation is difficult to achieve. CPT-298 is formulated to migrate through rust, eliminate corrosion, penetrate to the bare metal and stop further corrosion. CPT-298 contains a migrational and penetrating molecule that modifies the surface rust into a hydrophobic passive layer. CPT-298 combines the above-mentioned technology with a high build moisture displacing resin with extremely low water vapor permeability. CPT-298 does not contain tannic or phosphoric acids or any heavy metals and is a low VOC and environmentally friendly formulation. Furthermore, it provides extensive long-term corrosion protection for poorly prepared substrates and prepares the surface and creates a profile suitable for a long-term top-coat.

CPT-298 is recommended for use on all steel surfaces as a rust converter high build primer. The product can be used in situations where proper cleaning or sandblasting is difficult. 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 CPT-298 to 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 CPT-298 should be applied within 20-30 minutes after the first application to ensure maximum protection. Allow to dry for 8-12 hours before applying a top coat.

LIMITATIONS

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 coating will continue to convert rust. Upon drying, the formulation will exhibit excellent base corrosion preventative performance.

PACKAGING AND STORAGE

CPT-298 is available in 5-gallon containers and 55-gallon drums.

Keep product from freezing. The shelf life of the coating is one year.
