PPG Industries Inc.PPG has completed qualification of all three grades of its non-chromate corrosion-inhibiting sealant. The sealant provides commercial, general aviation and military aircraft makers as well as maintenance, repair and overhaul shops with faster cure to reduce application cycle time for considerable cost savings.
PPG is the first manufacturer to provide a fully qualified chromate-free corrosion-inhibiting aerospace sealant in all three classes. PR-2870 sealant, which uses PPG-patented technologies, is widely accepted in the market due to its light weight and process benefits as a feasible alternative for chromated sealants, with several commercial and general aviation customers qualifying it.
PR-2870 sealant weighs 30% less by volume than Pro-Seal 870 sealant and is supplied in a two-part SEMKIT package or pre-mixed and frozen cartridge. It is qualified to U.S. Military Specification MIL-PRF-81733. This is often used by MRO shops and aircraft manufacturers to select products.
PR-2870 sealant is the result of PPG Industries' collaboration on a project sponsored by the Strategic Environmental Research and Development Program (SERDP) to make an eco-friendly corrosion-inhibitive sealant offering high performance.
PR-2870 Class C sealant can be utilized instead of C-8, C-12 and C-24 to reduce inventory. It cures 70% faster than traditional interfay sealants at ambient conditions, reducing cycle time to offer aircraft manufacturers and maintainers the potential for considerable cost savings.
