ANTI CORROSIVE COALTAR EPOXY SYSTEM
Chemical industries like fertilizer, paper, textile face more problems of water leakage than other industries. Similarly newly constructed houses, balconies, roofs are also susceptible to water leakage's. The problem becomes more severe in hill - station where rain fall is too high. Water leakage's create dampness in the wall and corrosion to steel. This is not only temporary problem but a problem which has got permanent effect on the construction. Use of Epoxy Resin 520 / Coaltar Hardner ( Coaltar base epoxy system ) does not only stop the further leakage's but also strengthens the existing structure.

Method Of Application
- To get improved adhesion it is necessary to clean the surface before applying system in such a way that no traces of oil, dust remain on it. Plenty of water and mild acids are suggested. Surface should be made rough by coarse wire brush or by sand blasting
- Apply Resin / Hardner mixture to get good adhesion. It is necessary to give minimum two coats ( wet on wet ). If the problem is severe then additional third coat also may be given
