Advantages
- Resists most chemical environments when used with recommended topcoats
- Resists water and corrosion
- Provides good anti-corrosion protection
- Facilitates adhesion of finish onto difficult substrates
- Non-toxic, safer to use as compared to chromate versions
Application
Suitable for use on blast-cleaned steel where a complete epoxy system is required. It is suitable as a patch primer for the treatment of manually prepared steel.
As an anti-corrosive primer on steel surfaces.
Application Methodology
Remove dust, flakes, or other foreign particles by jet or dry air and clean the surface mechanically or by grinding to make it smooth before application Thoroughly dust down the surfaces Remove the majority of rust scales from the surface of rusting steel structure/reinforcement by wire brush, chipping, or grinding Ensure that the substrate temperature is in the range of 10°C – 110°C Apply CLI Sprayable Rust Remover on the surface where the wire brush is not reachable and allow the surface to dry for 30 minutes Apply CLI Prime Zn 40 on a dry surface Mix Comp A and Comp B in the ratios of 100:10 by weight (or as mentioned on the container) Apply CLI Prime Zn 40 by brush, roller, or spray. When applied by airless spray gun, ensure a minimum working pressure of 140 kg/cm² with a spray tip size of 0.43 – 0.53 mm and a spray tip angle of 65°. It is important that the base and the hardener are at a minimum temperature of 15°C when mixed for satisfactory spray application CLI Prime Zn 40 may be overcoated with conventional paints or twopack epoxy paints and polyurethane. Over-coating can be done after 8 – 10 hours; however, it is recommended to coat after 12 – 24 hours of application of the primer to obtain superior performance.
