PR1773B2 is a polysulfide sealant that is low-sag and resistant to corrosion. It is popular thanks to its large temperature range of -54 degrees Celsius to 121 degrees Celsius. PR1773B2's seals are removable, and the compound works especially well in high or low temperature environments where a somewhat elastic thixotropic paste is necessary. It prevents corrosion between common materials. PR1773B2 is functional with many aerospace substrates and is cured with magnesium dioxide.
