Chemola™ Desco 990-GT is a water insoluble synthetic valve lubricant and anti-seize for use in extreme high temperature environments such as geothermal applications. It is highly resistant to water and aqueous solutions (alkalis, acids). The solid lubricant additives contained in Chemola™ Desco 990-GT allow a greater degree of lubrication at temperatures where most lubricants fail.
Geothermal, steam, kiln car bearings and forging operations.
