Description
Momentive RTV108 Silicone is a general-purpose elastomeric sealant widely used in general-aviation maintenance for sealing non-structural gaps, joints, and openings on aircraft components. Owners and mechanics working on Cessnas, Pipers, and Beechcrafts often rely on RTV products to seal around inspection plates, cabin windows, antennas, and avionics installations where a flexible, durable seal is needed without structural load-bearing requirements.
This silicone-based sealant cures to form a resilient rubber-like material that tolerates temperature cycling and maintains flexibility in flight conditions. Before use, confirm compatibility with your specific aircraft material and consult your maintenance manual or a qualified mechanic to ensure RTV108 is appropriate for your intended application. Storage and cure times can vary, so review the manufacturer’s guidance and follow proper surface preparation for best results.
