Uses :
As a filler material in joints provided
beneath the seleant to impart shape &
optimize the seleant quantity, increase
the bonding area of seleant to adhesing
side surface.
Advantages :
1) Fuel / Solvent / Water / All
Weather Resistant.
2) Excellent movement accomodations
3) Provides support & shapes to sealants
: There by increasing contact area. |
