What is a polysulfide sealant.
Polysulfide:
Poly- Many; multiple Sulfide – SO2 (1 Sulfur atom, 2 Oxygen atoms)
This is what the word polysulfide means on a dictionary level, but that
probably doesn’t do much good to someone wanting to find out what it
does. Polysulfide compounds area very strong covalent bonded chemical
that can withstand the forces of weather better then most out on the
market today. They create watertight seals and protect against wind. (a
little water is actually commonly believed to help the compound take
affect more quickly)
This compound was used to patch up bullet-riddled aircraft during WWII.
If it can stand up to that task, it should be able to handle anything
you throw at it. Polysulfide has been in use since the ‘20s, (Thiokol
Polysulfide Technology, named for the man who invented it) but it really
came to shine in the 1940s and after, as one of the most effective
aerospace sealants found. It’s high performance and the ease at which it
can be used has made it perfect for things like aircraft fuel tanks, and
high-tension joints.
