Bonding of metals in other applications.Instructions for useUsing a manual or pneumatic sealant gun, apply sufficient Soudabond 641 into the cut window profile and slide the corner piece (within the skin formation time) into the window profile. Additional moistening is necessary to accelerate curing. Be careful not to wet the cut edges; therefore, AluSeal is best applied to the cut edge before injecting Soudabond 641. Another option is to immerse the corner piece in water just before assembly, so that no water gets on the cut edges or AluSeal. The use of Soudabond 641 is best limited to the pre-injection method (application before assembly).
