PPG Aerospace Offers GA Aircraft Windshield Hump Seal Repair Kits

PPG Industries’ aerospace transparencies group has introduced kits for repairing exterior moisture seals, or hump seals, of windshields on general-aviation aircraft. The new hump seal repair kits are similar to ones PPG Aerospace launched in 2012 for use with windshields on commercial aircraft.

“These new kits provide general-aviation aircraft owners and operators everything they need to repair a seal to OEM specification on an installed windshield and extend service life,” said Aaron Anderson, PPG Aerospace global segment manager, transparencies repair services.

Wind, rain and sun exposure cause a windshield’s exterior moisture seal to degrade over time, Anderson said. Keeping the seal in good shape maintains protection against moisture ingress that can affect service life.

Seventeen types of kits have been created for repairing windshield moisture seals on various general-aviation aircraft, including Bombardier, Cessna, Gulfstream, Hawker Beechcraft, Piaggio and Pilatus airplanes. The kits come in easy-to-carry boxes and contain chromate-free PR-1425CF windshield sealant and PR-1861 adhesion promoter by PPG Aerospace. Also included is a hump seal forming tool that will ensure the repaired seal has the same shape as the original moisture seal.

PPG Aerospace Hump Seal Repair Kits are available through PPG’s global network of application support centers, which are listed on the PPG Aerospace website at www.ppgaerospace.com.
