Sealants
The main difference between adhesives and
sealants
is that sealants typically have lower strength and higher elongation than do adhesives. The main objective of a sealant is to seal assemblies and joints. They adhere to the substrates and
resist environmental conditions
to remain bonded over the required life of the assembly. Sealants contain
inert filler
material and are formulated with an elastomer to give the required flexibility and elongation. They usually have a paste consistency to allow filling of gaps between substrates.
