MASTICMFD. to IS:9862
GENERAL PURPOSE ANTICORROSIVE, READY-MIX BITUMINOUS COATING / PAINT
MASTIC is bitumen based anticorrosive, odorless, tasteless and non - toxic ready mix brushable paint. It is also lead-free and resistant to acid, alkali, water and chlorine. It is most efficient and economical protection against corrosion.
The effectiveness of an anticorrosive coating is directly related to its resistance against moisture. Initially many coatings are waterproof, but on ageing its ability as a protective coating is lost. Even the minute penetration of moisture is quite sufficient to encourage corrosion on the steel surface underneath. A good protective coating should have adhesive properties to the surface on which it is applied.
MASTIC is manufactured by adopting strict quality control, so that product application can be done easily and quickly by BRUSH / SPRAY and it dries rapidly to give a smooth glossy black finish.
MASTIC is used for the protection of apparatus, equipment, machines and drinking water tanks, pipe, fluid containers etc. Minimum two coats will be required, after the first coat has thoroughly dried.
The surface should be free from dust, grease, rust and loose particles.
