August 2020 3M Scotch-Weld Neoprene High Performance Rubber & Gasket Adhesive EC-1300 and EC-1300L Technical Data Sheet Product Description 3M Scotch-Weld Neoprene High Performance Rubber & Gasket Adhesives EC-1300 and EC-1300L are the most versatile of our rubber and gasket adhesives. They may be used to bond metal, wood, most plastics, and neoprene, reclaim, SBR, and butyl rubber. They have high immediate strength and excellent heat resistance. Features 3M Scotch-Weld Neoprene High Performance Rubber & Gasket Adhesive EC-1300L meets specification requirements of MMM-A-121. Temperature performance range is -30F (-34C) to 300F (149C). Bonding Range: 3M Adhesive EC-1300 up to 12 minutes 3M Adhesive EC-1300L up to minutes. Bonds neoprene, SBR, butyl and other types of rubber to various substrates. 3M Adhesive EC-1300L is a lower solids viscosity version of 3M Adhesive EC-1300, for easier brushing and sprayability.

Surface Preparation Remove all dust, dirt, oil, grease, wax, loose paint, etc. Wiping with a solvent such as methyl ethyl ketone (MEK)* will aid in preparing the surface for bonding. 2. Application Temperature For best results, the temperature of the adhesive and surfaces to be bonded should be at least 65F (18C). If stored below 30F (-1C), allow adhesive to warm to room temperature by placing in a warm room only (do not exceed 120F 49C ) followed by thorough agitation. 3. Application Stir well before using. Brush, flow or spray a thin, uniform coating of adhesive to each surface. A coating of 2 2.5 gms to 3.5 gms/ft. dry weight per surface is recommended. Porous surfaces may require more than one coat. A uniform, glossy film indicates sufficient adhesive. 4. Drying Time Allow adhesive to dry until no longer wet (maximum dry time about 4 minutes). 5. Bonding Range Once dry, these adhesives have a short bonding range (up to 8 to 12 minutes). 6. Curing Time Position surfaces carefully before assembly. Bonding is immediate upon contact. Apply sufficient pressure to ensure good contact between coated surfaces. Bonded parts may be handled immediately. 7. Reactivation Greater immediate strength may be obtained by solvent reactivation. To solvent reactivate, coat both surfaces with adhesive and allow to dry tack free. Lightly wipe one surface with methyl ethyl ketone (MEK)* and complete bonding within 30 seconds. 8. Cleanup Use a solvent such as 3M Solvent No. 2* or methyl ethyl ketone (MEK)* to clean brushes immediately after use. Excess adhesive may be removed from other surfaces with 3M Citrus Base Cleaner* or equivalent. *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturers precautions and directions for use.
