•environmental “prevent entry of fluids, body fairings” •corrosion areas “lavatories/ galleys” •aerodynamic areas •electrical areas “between floor boards above avionics bay”
2
this is applied to fill channels and voids in the structure that require sealant.
3
this is applied along the edges of the structural joints and further protects against fluid and air pressure leaks
4
this is applied between 2 mating surfaces to prevent corrosion and to keep fluids or air pressure from passing through the joint
5
this is applied to holes and voids in structure before assembly where it is not possible to do so afterwards
6
•low viscosity •applied by brush •applied to fasteners
7
•does not sag or run on vertical surfaces •applied by semco gun or spatula •injection, fillet, fay
8
•used when long squeeze out life is required •intermediate viscosity sealant •Fay surfaces •brushing or rolling on surfaces

fillet seal
31
1. push sealant into hole on pressure side 2. make sealant into smooth fillet on adjacent surfaces 3. for large holes use masking tape for temporary bottom
32
masking tape, plastic sheets, wax paper
33
used where large areas need to be masked for painting
34
used when wet sealant needs to be covered temporarily
35
minimum
36
time in hours after mixing during which a faying surface sealant can be squeezed out of a joint when fasteners are installed
37
time in hours after mixing that is required for the sealant to cure sufficiently so that it will not transfer to the finger or to a plastic film
38
