PR-1771® Corrosive Inhibitive Sealant Non-Chromate Low Gravity - 6oz Semkit™

PR-1771® Class B is a two-part, non-chromate, low gravity, corrosion inhibitive sealant designed for filling and smoothing gaps, slots and depressions on exterior aircraft surfaces. It also provides an effective barrier against the common causes of corrosion in aircraft today. PR-1771® Class B will resist aircraft fuels (aviation gasoline or jet fuel), oils and hydraulic fluids.

PR-1771® Class B is a two-part manganese cured, based on Permapol P-5 liquid polymers, a chemically modified improved class of polysulfide polymers.

The mixed compound is a thixotropic paste which can be readily applied by spatula or extrusion gun. It does not flow from vertical or overhead surfaces.
