Description
PR-2001 Class B is a rapid-cure, low-odour sealant from PPG Aerospace, built on epoxy-cured Permapol P-3.1 polythioether. The low-sag paste can cure at low temperatures and is unaffected by humidity changes. PPG rates it from -62°C to 160°C with intermittent excursions to 216°C; the B-1/2 grade is tack free in under 2 hours.
The manufacturer describes it for fillet sealing of aircraft integral fuel tanks, fuselage sealing and aerodynamic smoothing, applied by extrusion gun or spatula. PPG notes it keeps its elastomeric properties after prolonged jet fuel and aviation gas exposure.
