Use Of Threadlockers and Sealants
Threadlocking adhesives and sealants are specified throughout this manual and should be used where indicated.
Threadlocking compounds normally break down at temperatures above 350° F (175° C). If a screw or bolt is hard to
remove, heat it using a small propane torch to break down sealant. When applying sealants, follow instructions on
container. The sealants listed below are recommended for use on WACKER equipment.
