PR-1428 Class B is a low adhesive sealant. It has a service temperature range -65┬░F (-54┬░C) to 250┬░F (121┬░C), with intermittent excursions up to 250┬░F (135┬░C). The material is designed for use as an access door sealant or in the fabrication for form-in-place (FIP) gaskets. It can also be used to protect electrical wired, terminals and equipment against fuel moisture, dirt and short circuits.
PR-1428 Class B is a two-part, manganese dioxide cured, polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a removable seal to common aircraft substrates.
These sunglasses were a gift to our grandson. He is a fairly new pilot and wanted these sunglasses as a birthday gift. He is very happy with them.
The staff at Pilots HQ were great to deal with and managed pto get the sunglasses to me just in time for our grandson’s birthday.
Thanks for the help.
Heard about Boelube for years. Finally had a chance to try it on several projects. It definitely works well and better than anything else I have ever tried. Would recommend.
