Topcoat SF (Stone Finish) - Single Coat PU System

TOPCOAT SF is a chemical and heat resistance material, up to a temperature of 180 deg.C., suitable for application by brush or spray. It is an excellent coating for corrosion resistance, insulation & damp walls etc. Coating achieved with this PU is extremely hard and is resistance to oil, alkali, alcohol, salt water, sulphuric acid solution up to 30% concentration level (24 hours).

It is strongly recommended for coastal areas, where the humidity levels are very high and some times, it goes up to 90-95% and no other coating takes the grip, because of invisible slat deposit on the structures. This coating will protect the structures, steels and equipments in Oil Refineries, Solvent Chemical Industries and Onshore structures, which are subjected to severe saline conditions and where the problem is proper drying and curing of the polymer, after being coated.

This coating is resistance to Aggressive corrosion through micron build up is between 15-25 microns. Depending on the base surface and the spraying conditions, this coating dries in presence of moisture and attains strength.
