Type of Project:
Maintenance painting of hydro transmission towers.
Project Description:
Apply Termarust corrosion protection coating on power transmission steel structures.
Reason project was undertaken:
There was a severe corrosion problem on the structures. Existing corrosion protection was beyond its life and new corrosion protection was required.
Name and location of facility:
Ontario Hydro, Hamilton (Toronto), Ontario, Canada
Project start and completion dates:
June to September 1993
Service Environment:
Industrial
Surface Preparation: Methods, degree of cleaning, profile:
SP2

Brush and mitts
Coating system, number of coats, dry film thickness per coat, etc.:
Application of Termarust 2100 (RAVCS®) Primer/Topcoat 6 to 10 mils DFT.
Safety and Environmental Protection Measures:
None
Unusual Job conditions:
Finding an environmental and user friendly coating system that would stop the corrosion process. After 200 systems were considered and tested, the Termarust 2100 (RAVCS®) Primer/Topcoat provided the best performance.
Evidence of good performance:
No rusting or deterioration of the coating has occurred after almost 10-years of service life.
Why Termarust was used:
Over 200 systems were considered and tested. The Termarust 2100 (RAVCS®) Primer/Topcoat provided the best performance (lowest overall cost and long term service life). Termarust 2100 (RAVCS®) Primer/Topcoat met all the criteria and is ideal for Transmission Towers.
