TWO COMPONENT ANTI CORROSIVE ZINC PHOSPHATE PRIMER
CLI Prime Zn 40 is a two component, polyamide cure zinc phosphate anti-corrosive epoxy primer for steel surfaces. CLI Prime Zn 40 is composed of zinc phosphate, non-lead pigments and inert mineral fillers in a polyamide binder with aromatic hydrocarbons and alcohol solvents.
ADVANTAGES
• Resists most chemical environment when used with recommended topcoats.
• Resists water / corrosion.
• Provides good anti-corrosion protection.
• Facilitates adhesion of finish onto difficult substrates.
• Non-toxic, safer to use as compared to chromate version.
APPLICATION
Suitable for use on blast cleaned steel where a complete epoxy system is required. It is suitable as a patch primer for treatment of manually prepared steel.
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 majority of rust scales from surface of rusting steel structure / reinforcement by wire brush, chipping or grinding.
• Ensure that the substrate temperature is in the range of 10 0C – 110 °C.
• Apply CLIRustOff on the surface where wire brush is not reachable and allow the surface to dry for 30 minutes.
• Apply CLI Prime Zn 40 on dry surface.
• Mix Comp A and Comp B in the ratios of 5.5 : 1 by volume and in the ratios of 8.9 : 1.1 by weight.
• Apply CLI Prime Zn 40 by brush, roller or spray. When applied by airless spraygun, ensure that the minimum working pressure of 140 kg / cm2 with a spray tip size 0.43 – 0.53 mm and a spray tip angle of 65O . It is important that the base and the hardener are at the minimum temperature of 15 °C when mixed for satisfactory spray application .
• CLI Prime Zn 40 may be over coated with conventional paints or two-pack epoxy paints and polyurethane. Over-coating can be done after 8 - 10 hrs; however, it is recommended to coat after 12 - 24 hrs of application of primer to obtain superior performance.

HEALTH & SAFETY
• Use mask, nose cover and hand gloves during application.
• Clean hands with soap water after application.
• Ensure adequate ventilation and avoid inhalation of vapours as some people are sensitive to resins, hardeners and solvents.
• Avoid contact with skin / eyes. In case of unlikely contact with eyes, rinse immediately with plenty of clean water, then cleanse with soap and lukewarm water and seek medical advice. Do not use solvent to clean the contacted area.
• Prevent swallowing. In case of unlikely swallowing, seek medical attention immediately. Do not induce vomiting.
