Description
3M 847 Rubber and Gasket Adhesive is a contact cement formulated to bond rubber, gasket materials, leather, and similar flexible substrates to metal, plastic, and composite surfaces. This product serves general-aviation maintenance and repair by enabling secure attachment of weather seals, fuel-system gaskets, door gaskets, and vibration-damping rubber components commonly found in Cessna, Piper, and Beechcraft airframes. Contact adhesives require application to both surfaces, a brief open-time interval for solvent flash-off, and firm pressure to develop full bond strength.
Mechanics and owner-pilots should verify material compatibility before use, as rubber and gasket adhesives perform best on clean, dry surfaces free of oil, dirt, and old adhesive residue. Surface preparation—sanding or chemical cleaning—directly affects joint durability. Always follow the manufacturer’s instructions for application method, cure time, and ventilation requirements. Store in a cool, well-ventilated area away from ignition sources, and confirm the product meets your airframe’s maintenance manual or STC requirements before use on critical sealing applications.
