How to use


The contact surfaces must be dry and free of oil, grease and dirt. Rubber parts must be free of talcum and release agents. For cleaning we recommend Teroson A or FL.


TEROSON SB 412 is applied from tubes or cartridges as a bead into or onto the seam or joint to be sealed. When applying TEROSON SB 412 from nozzle cartridges, the cartridge nipple should be cut off above the thread and the nozzle should be screwed on and cut at an angle to the required opening size. 


Adhesive residues/contaminations can be removed before drying with cleaner TEROSON FL.
