DESCRIPTION
MASTER COAT - ZN is a zinc rich, heavy duty industrial coating based on epoxy resin and hardner. Master Coat - ZN is especially developed for metal surfaces which are subjected to constant spillages of water or subjected to marine atmosphere. Metals coated with MASTER COAT - ZN show excellent resistance to sea water. The product is supplied as two-pack system comprising grey coloured base and hardener. It requires only on site mixing to produce an easily applied decorative and chemical resistant finish.
PRIMARY USE
For protection of metal surfaces subjected to heavy chemical atmosphere and constant spillages of water. As a decorative coating to marine vessels and marine structures.
GUIDE TO APPLICATION
Ensure adequate ventilation during application. Master Coat - ZN coating can be applied either using lambs wool rollers or short haired stiff bristled nylon brushes. Generally two coats are recommended. The second coat is applied on the second day of the first coat or at an interval of atleast of atleast eight hours.

CHEMICAL RESISTANCE
Master Coat - ZN is resistant to the following typica- lly encountered chemicals apart from being resistant to sea water : Formaldehyde 40% solution, Sulph-
uric Acid 30% solution, Wine, Acetic Acid 5% solut- ion, Diesel-Oil, Hydrochloric Acid 50% solution, Aviation Hydraulic Fuels (skydrol), Nitric Acid 10% solution and Vegetable oils. Master Coat-ZN coatings may slightly change in color in certain chemical environments but the chemical resistance of the Master Coat - ZN film remains unchanged.
OVER COATING
Where areas need to be over coated due to damage etc., it is important that the area to be treated are well abraded using stiff rotary wire brush or coarse sand paper to give adequate key. Completely strip off any unsound coating and proceed with over coating as in new work.
DIRECTIONS FOR USE
Surface Preparation :
The substrate should be a smooth or semi-smooth sound surface such as concrete or metal. It is most Important to ensure that thorough surface preparation is undertaken prior to application of the Master Coat-ZN coating.
Concrete :
Ensure concrete is free from excessive laitence, grease, oil, curing compound, etc. Ensure concrete is sound. Cut back wherever necessary and make good using suitable cementitious or epoxy repair system. Ensure all blow holes and surface imperfections are made good prior to application of the coating. Wire brushing followed by degreasing, acid etching or grit blasting may be necessary to remove laitence. Ensure concrete is atleast 28 days old.
Steel :
All previous surface treatments should be removed taking the surface back to base metal. The base metal should be abraded and preferably shot blasted. Cleaning with solvent or a strong detergent is advisable to ensure surface is free from grease etc. Do not allow surface to re-oxidse before application of Master Coat-ZN.
Mixing :
Master Coat-ZN is supplied in two pre-weighed components, Base and Reactor. No additions or ommissions are required. Add reactor contents to the base components and stir thoroughly for 3-4 minutes using a slow speed hand drill fitted with a paddle. Mix until a uniform colour is achieved. Apply in two coats.
EQUIPMENT CARE
All equipment must be cleaned immediately after use with cleaning solvents. Similar procedures should be adopted for break periods exceeding fifteen minutes.
HEALTH AND SAFETY
Epoxy products generally cause irritation to the skin. Use of hand gloves by the workers is advised. Upon completion of day’s work all the packing material should be burnt and buried.
COVERAGE
4 to 5 square meter per kg per coat. Two coats are recommended.
