PPG Industries’ Aerospace business recently announced that its PRC®FIP strip form-in-place sealant tape has qualified to SAE International’s Aerospace Material Specification 3379.
Over the last 50 years, the aerospace and aircraft industries have used silicone in an ever-growing number of applications. Silicone inherently has high dielectric strength (typically ≥ 500 V/mil) and a large coefficient of thermal expansion (CTE), allowing it to absorb stresses during thermal cycling.
PPG recently announced that the PPG Industries Foundation has donated $15,000 to the Air Force Museum Foundation for construction of a fourth major building.
SAE International announced details of its 2013 Aerospace Government and Industry Meeting, which will take place September 23 in Montreal, Quebec, Canada.
This company’s aerospace transparencies group announced it is introducing kits for repairing exterior moisture seals (or hump seals) of windshields on general-aviation aircraft.
Sealants are generally chosen for their ability to fill gaps, resist relative movement of the substrates, and exclude or contain another material. Sealants are generally lower in strength than adhesives, but have better flexibility. Usually, a sealant must effectively bond to a substrate in order to perform these functions.
