Suggested use
ZF provides good corrosion protection on rusted metals with minimum surface preparation, it may also be applied to UHP waterbased, bristle blasted or grit-blasted surfaces as an inhibitive coating or primer. ZF can be used entirely on it’s own, in single or multiple coats or can be overcoated with other Plasmet coatings to give a smoother, more easily cleaned and chemically resistant surface. ZF is tough, durable and tolerant of vehicular traffic. It can be used for protection in both atmospheric and immersed conditions. In atmospheric conditions ZF may be used under decorative finishes such as polyurethane or enamel.
Limitations
Not suitable for immersion in strong acidic or alkaline environments unless overcoated.
Health & safety
WARNING: When using this product safety precautions should be observed. Avoid contact with skin or eyes, do not ingest. Protective clothing and eye protection should be worn. Ensure good ventilation a fume mask is only required in enclosed areas and areas of poor ventilation. Read the safety data sheet before use.
Surface preparation
Remove oil, grease and any other surface contaminates utilizing a suitable solvent, detergent cleaner or emulsifier. ZF will tolerate damp surfaces but excess moisture must be removed, dry is best. Most existing firmly bonded coatings can be tolerated and overcoated by ZF. For best results the surface should be prepared using bristle blaster or for larger areas localized abrasive blasting. Local repairs may be carried out using a wire brush or needle gun.
Storage life
2 years minimum in unopened aerosol tins, stored at 41-104°F (5°C-40°C).
Practical spreading rate
34 sq ft/ltr at 6 mil dft (3.2 m²/litre at 150 micron dft)
Note: This information is given in good faith but may increase dependent upon the environment and the skill and care of the application. Corrocoat accept no responsibility for any deviation from this value.
Overcoating
Minimum: 6 hours at 49-53°F. May be overcoated as soon as touch dry at temperature above 53°F (12°C).
Maximum: 7 days for uncontaminated product
Note: During testing no intercoat failures were witnessed, at all temperatures, mechanical performance will improve with time.
Cleaning solvent
Xylene, Toluene or Methyl Ethyl Ketone.
Application
Shake the tin until the ball starts to rattle to mix the base.Remove the bottom cap and attach the “o” ring to the plunger. Pull the plunger firmly down keeping downward pressure on the ring. Rotate the ring by 720°. A knife inside the tin cuts the seal allowing the base and hardener to mix. Shake the tin well for circa 2 minutes. The plunger may be pushed back to its original position, to allow the tin to be stood up if required. Spray apply the material, best results are achieved with the spray nozzle 30-40 cm from the surface and moving the nozzle quickly from side to side. If all the material is not used on a single application, shake well before reusing. The coating should be applied thin enough to prevent runs and sags. Wet film thicknesses of between 6-12 mils (150-300 microns) are recommended. May be applied as a single or two coating system. This should be checked on site with a wet film comb. This material will tolerate high humidity during application but surface temperatures should be at least 37°F (3°C) above the dew point.
