Threadlockers and Sealants

Threadlockers and Sealants (continued)

Threadlocking adhesives and sealants are specified throughout this 
manual by a notation of “S” plus a number (S#) and should be used 
where indicated. Threadlocking compounds normally break down at 
temperatures above 175°C (350°F). If a screw or bolt is hard to 
remove, heat it using a small propane torch to break down the sealant. 
When applying sealants, follow instructions on container. The sealants 
listed are recommended for use on Wacker equipment.
