Surface Preparation
For optimum strength structural bonds, paint, oxide films, oils, dust, mold release
agents, and all other surface contaminants must be completely removed. 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. A instant adhesive activator may be required if there are bonding gaps or
3. Bond speed is typically very fast so ensure that parts are properly aligned before
4. Product is normally hand applied from the bottle. Apply sparingly to one surface
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™ Super Fast Instant Adhesive bonds are
4. Cyanoacrylate bond resistance to most oils and solvents is excellent. Long term
*Note: When using solvents, extinguish all ignition sources, including pilot lights,
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.
3M™ Scotch-Weld™ Super Fast Instant Adhesives can be expected to have a
shelf life of one year from the date of shipment from 3M when stored under
refrigerated conditions.

(e.g., polyethylene, polypropylene) or if substrates have acidic surfaces
(e.g., paper, leather).

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.
suitable for use up to about 180°F (82°C). At 180°F (82°C) the bonds will be
approximately 70% of the strength at room temperature and at 212°F (100°C)
about 50% of full strength.
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.
