DESCRIPTION
MASTER COAT - RI is a high build, heavy duty industrial coating based on epoxy resin and hardner. Master Coat - RI is especially developed to provide anti corrosive protective coating to metals and concrete surfaces which are subjected to aggressive chemical atmosphere. The product is supplied as a two-pack system comprising of dark red base and hardener. It requires only on site mixing to produce an easily applied decorative and chemical resistant finish. Master Coat- RI coating can easily be built up to higher thickness by subsequent coats.
PRIMARY USE
For the external and internal protection of metallic surfaces as well as concrete structures which are subjected to chemical atmosphere. Master Coat-RI is resistant to continuous spillages of water and hence suitable for application on marine structures. The color of the coating is dark red and gives an aesthetic look.
GUIDE TO APPLICATION
Ensure adequate ventilation during application. Master Coat - RI coating can be applied either using lambs wool rollers or short haired stiff bristled nylon brushes. The second coat is applied on the second day of the first coat or at an interval of atleast eight hours.

CHEMICAL RESISTANCE
Master Coat is resistant to the following typically encountered chemicals : Saline water, Formal dehyde 40% solution, Sulphuric Acid 30% solution, Wine, Acetic Acid 5% solution, Diesel-Oil, Hydrochloric Acid 50% solution, aviation Hydraulic fuels Nitric Acid 10% solution and Vegetable oils. Master Coat-RI coatings may slightly change color in certain chemical environments but the chemical resistance of the Master Coat-RI 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 for 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-RI 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 re- move 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-RI.
Mixing :
Master Coat-RI is supplied in two pre-weighed components, Base and Reactor. No additions or omissions 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.
