CASE STUDY
Alocit 28.95 and 28.15 were originally specified for the service tunnel of the Gornergrat-Bahn, a rack-railway in the Swiss Alps. Fifteen years later, Alocit products were chosen again because of their record of durability, outstanding adhesion and resistance to oil and other corrosive materials.
The service tunnel is cut 250 metres into the mountainside and is used for the maintenance of trains and rolling stock as well as for the storage of materials. Its walls and floors suffer from constant exposure to moisture, dirt and oil. Engine oil is drained directly into channels under the tracks to be carried off to special oil separators, but no part of the tunnel escapes from the contaminating effects of this damp, subterranean environment.

Alocit 28.95 was used as a primer because of its ability to adhere to oily and damp substrates, with 28.15 as the finishing coat. Surface preparation only required the removal of loose and flaky material by wire brush. After application, in this case by brush, the Gornergrat-Bahn was ready for at least another 20 years hard use.
