3M™ Scotch-Weld™ EC-5816 Elastomeric Coating – Gallon Can — Professional Grade Elastomeric Coating

The 3M™ Scotch-Weld™ EC-5816 Elastomeric Coating – Gallon Can is a high-performance elastomeric coating designed for critical aerospace, industrial, and MRO applications where surface protection and long-term durability are non-negotiable. Manufactured by 3M and identified by part number 7000009148, this product is engineered to comply with applicable aerospace and industry specifications and is trusted by MRO facilities, OEM manufacturers, and maintenance professionals across aviation and defense industries.

Available in a Gallon Can format and finished in Gray, this coating forms a tough, adherent film on properly prepared substrates including aluminum alloys, steel, composites, fiberglass, and other materials commonly used in aerospace and industrial assemblies. Its formulation delivers superior resistance to fuels, hydraulic fluids, solvents, moisture, and UV exposure — making it a reliable choice for both interior and exterior aerospace applications.

The elastomeric coating is engineered to maintain its protective properties under the thermal cycling, vibration, and mechanical stress conditions experienced throughout a component’s service life. Whether used as a topcoat, primer component, conversion coating, or sealant depending on the product type, it provides the consistent performance demanded by aviation maintenance and production environments.

Application is designed to be practical using standard industrial equipment. Surface preparation including degreasing, sanding or abrading, and application of a compatible primer (where applicable) is recommended to achieve maximum adhesion and service life. Always consult the manufacturer’s product data sheet (PDS) for mixing ratios, pot life, application thickness, and cure schedule before beginning work.

The 3M EC-5816 in Gallon Can is an excellent choice for professionals seeking specification-compliant, reliable coating solutions. Contact us for bulk pricing, availability, technical data sheets, and support to confirm this product meets your operational requirements.
