New Chromate Free Corrosion Inhibiting Sealant Benefits Aerospace Industry

Posted By asc, Monday, February 29, 2016

PPG Industries Inc. has announced the release of three revolutionary corrosion inhibiting sealants. These are the first chromate free sealants to be approved for use in commercial and military aerospace applications. The sealants are not only more environmentally friendly than their predecessors; they are also 30% lighter than traditional chromated sealants, and take 70% less time to cure. The sealants use patented technologies to inhibit corrosion on metal in aerodynamic smoothing, structural surface sealing, fay sealing and pressure fuselage sealing aircraft applications. The sealants are ideal for aircraft manufacturers as well as maintenance, repair and overhaul workshops.


The sealant, PR-2870, was developed by PPG Industries in collaboration with the Strategic Environmental Research and Development Program (SERDP) and will allow for substantial cost savings for aircraft maintenance and manufacturing companies thanks to the reduced cycle time resulting from faster curing. It is available either as a two-part adhesive, or as a ready-mixed, frozen cartridge and can be used to replace C-8, C-12 and C-24 sealants, allowing for a reduced inventory in aerospace manufacture and maintenance operations.
