PR1776 is a low gravity aerospace sealant. As a two-part high temperature resistant sealant, PR1776 is primarily used for fillet sealing of fuel tanks, pressurized cabins and other aircraft sealing applications. When cured, PR1776 exhibits excellent elastomeric properties even after lengthy exposure to jet fuel, aviation gas and petroleum-based lubrificating oils. This sealant shows superb sealantness to stainless steel, titanium, aluminum and other metals. PR1776 may be applied by extrusion/injection gun or spatula.
