Scotch-Weld™ General Purpose Instant Adhesives EC5 • EC40 • EC100 • EC2500 • ECI Gel Technical Data April 2016 Product Description 3M™ Scotch-Weld™ General Purpose Instant Adhesives are single component, high strength ethyl cyanoacrylate adhesives designed to bond to a variety of substances including most plastics, rubbers, metals, and other common substrates. They are available in a wide variety of viscosities. Specific Features • 3M™ Scotch-Weld™ General Purpose Instant Adhesive EC5 is a very low viscosity, cyanoacrylate that is fast bonding. It is recommended for use on assemblies with very close-fitting parts and smooth, even surfaces. It can be used to wick into bonding gaps of assembled parts.

  • 3M™ Scotch-Weld™ General Purpose Instant Adhesive EC40 is a low viscosity cyanoacrylate that is fast curing. It is recommended for use on assemblies with close-fitting parts and smooth, even surfaces.
  • 3M™ Scotch-Weld™ General Purpose Instant Adhesive EC100 is a low viscosity cyanoacrylate that is fast curing and useful for general purpose bonding.
  • 3M™ Scotch-Weld™ General Purpose Instant Adhesive EC600 is a medium viscosity cyanoacrylate that resists migration from the bond area. It can be used for wire tacking on printed circuit boards.
  • 3M™ Scotch-Weld™ General Purpose Instant Adhes ive EC2500 is a high viscosity liquid cyanoacrylate with an even slower cure rate. It is also used on assemblies where parts are not close-fitting, surfaces are rough or porous, or where time is required to align parts before cure.
  • 3M™ Scotch-Weld™ General Purpose Instant Adhesive ECI Gel is an industrial strength thixotropic gel for maximum gap filling. It is suitable for bonding poorly mating components and for porous substrates such as ceramic and can be used on vertical surfaces as it will not drip or slump.

However, the amount of surface preparation depends on the required bond strength and the environmental aging resistance desired by the user. Typical quick surface preparation would include wiping with a clean solvent (such as isopropyl alcohol*), abrading the surface with a clean fine abrasive, and then wiping again with a clean solvent to remove loose particles. Directions for Use 1. Ensure that parts are clean, dry, and free from oil and grease. 2. An instant adhesive activator may be required if there are bonding gaps or porous substrate surfaces, if substrates are low surface energy plastics (e.g., polyethylene, polypropylene) or if substrates have acidic surfaces (e.g., paper, leather). 3. Bond speed is typically very fast so ensure that parts are properly aligned before dispensing. 4. Product is normally hand applied from the bottle. Apply sparingly to one surface and press parts firmly together until handling strength is achieved. As a general rule, as little cyanoacrylate as possible should be used. Over application will result in slower cure speed and lower bond strength. Cured Bond Characteristics 1. Full bond strength will typically be achieved within a 24 hour cure time. 2. Low humidity or low temperature conditions will slow down the cure rate. 3. After curing, 3M™ Scotch-Weld™ General Purpose Instant Adhesive bonds are suitable for use up to about 180°F (82°C). 4. Cyanoacrylate bond resistance to most oils and solvents is excellent. Long term humidity, moisture, or water immersion may affect the strength of a cured cyanoacrylate bond depending on the substrates and the bond gap. Testing is recommended to evaluate the effect. *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use. - 3 -

3M™ Scotch-Weld™ General Purpose Instant Adhesives EC5 • EC40 • EC100 • EC2500 • ECI Gel Storage For short term storage (<30 days), keep adhesive in a cool (60°F to 80°F [16°C to 27°C]), dry place out of direct sunlight. Keep containers tightly covered and free of moisture. Refrigeration (40°F [4°C]) gives optimum long term storage stability.
