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.
