PR-2201 Class B is a two-part compound filled with nickel, cured with epoxy, and made of Permapol P-3.1 polythioether. The uncured substance is a paste that can be applied with an extrusion gun or spatula due to its low sag and thixotropy.
The cured sealant provides excellent conductivity and EMI/RFI shielding effectiveness. This material is an effective barrier against the common causes of corrosion on aluminium alloys or between dissimilar metals. The cured sealant is resistant to jet fuel and aviation gasoline (avgas) exposure.
If properly primed with PPG PR187 Adhesion Promoter (sold separately), this sealant shows excellent adhesion to common substrates found in aircraft.
