Staromastic 54: Mastic
Product Description :It is a specially developed epoxy mastic coating intended to be applied on inadequately prepared surfaces. It is a surface tolerant coating owing to its excellent wetting ability on the substrates.It is a two component, ambient curing system, which when mixed together in the recommended ratio, cures to a hard coating which has excellent adhesion and chemical resistance.
Uses:
Used as a universal primer for compromised surfaces where no grit blasting is employed as surface preparation methods.
Highly recommended for steel. structures, pipelines, tanks and offshore platforms.
Advantages:
Surface tolerant
High solids
Excellent adhesion on compromised surfaces
Excellent corrosion protection

Direction of use :
Remove oil, grease and any other contaminants by using solvents. Make full use of mechanical
tools, manual chipping or wire brushing to remove loose rust and scale. No grit blasting is needed.
Stir the resin part thoroughly and then mix one part of resin with one part of hardener by volume. Mix in
small portions enough to last for 2 hours or less. Apply by brush or spray. Allow to dry for 4 hours. Now the
surface is ready to receive intermediate or top coat. If the time is lapsed for more than 24 hours to receive
subsequent coats, the primed surface needs to be abraded to have mechanical key for subsequent coats. If the time
is lapsed for more than 24 hours to receive subsequent coats, the primed surface needs to be abraded to have
mechanical key for subsequent coats.
Storage & Self Life:
The product should be stored in accordance with national regulations. It should be kept in a cool, well
ventilated area, away from heat, direct sunlight, sparks and children. It contains inflammable solvents. Handle with care.
Mix resin and hardener as per the ratio. Use the mix solution within the pot life time.
Packaging
available in 20 kgs packs and has a maximum shelf life of 12 months in the un-opened condition
Handling & Safety
Observe reasonable care and employ ordinary hygienic principles such as washing the hands with soap and water
before eating or smoking. It is recommended to wear gloves, goggles and nose masks while application. Incase of
splashes on the skin, dampen the cloth with thinner and wipe the hands with the cloth. Wash then with soap and
water. Dried film is non toxic. Incase of contact with eyes, rinse with plenty of water and seek medical advice.
Incase of continuous exposure to vapours, the applicator should be immediately moved to get fresh air.
