Process for the Preparation of Zinc Rich Primer
Based on Alkali Silicate
Introductin
A unique process to make post cure
zinc silicate primer based on enriched sodium silicate
( where silica to alkali ratio high). It is thinable
with water. After application of the primer chemical
wash is given for curing the primer. Moreover it is
a maintenance free primer. The process is standardised
at a scale of 15 Litres/Day. A plant with a capacity
to manufacture 15,000 Litres of primer/annum costs approx.
Rs. 16 Lakhs Ideally suitable for small scale industries
