3M Scotch-Weld EC-1300 Neoprene Rubber and Gasket Adhesive – 5 oz Tube
3M Scotch-Weld EC-1300 is a high-performance, neoprene-based contact adhesive designed for demanding rubber, gasket, and flexible material bonding applications in aerospace, automotive, and industrial environments. Its high-strength, flexible bond film maintains adhesion to rubber, metal, plastic, fabric, and foam substrates under the challenging service conditions these joints encounter — including vibration, thermal cycling, moisture, and fuel exposure.
EC-1300 is an industry-standard aerospace adhesive with a long track record of reliable performance in aircraft interior panel bonding, rubber gasket and seal attachment, acoustic insulation bonding, and weatherstrip installation. Its neoprene chemistry provides excellent compatibility with neoprene and EPDM rubber compounds, creating strong, durable bonds between rubber components and their metal or composite mounting substrates.
The 5 oz tube provides a convenient application format for MRO maintenance operations, with the tube nozzle enabling precise bead and brush-on application. As a contact adhesive, EC-1300 is applied to both surfaces and allowed to flash off before joining, providing an immediate, high-strength bond on contact without the need for extended clamp time.

Technical Information
3M Scotch-Weld EC-1300 is formulated with a neoprene (polychloroprene) rubber polymer that provides excellent compatibility with vulcanized rubber substrates, creating strong adhesive bonds at the rubber-adhesive interface that resist the cohesive failure modes common to less compatible adhesive systems on rubber. The neoprene polymer also contributes to the high tack and aggressive initial bond strength that characterize high-performance contact adhesives.
The adhesive’s solvent carrier evaporates during the flash-off period after application, leaving a concentrated, active adhesive film on both bonding surfaces. The correct flash-off time is critical — joining too early (wet film) traps solvent and weakens the bond, while joining too late (over-dried film) reduces tack and may require re-activation. Ambient temperature and ventilation affect flash-off time and should be maintained within the recommended range per the 3M EC-1300 technical data sheet.
EC-1300’s yellow color distinguishes it from other adhesive types and provides visual confirmation of adhesive coverage on the bonding surface during application. The yellow tint becomes less visible as the solvent flashes off, with the adhesive appearing progressively more transparent as it dries to the active bonding state.
