Shelf Life Details 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.;Rite-Lok™ General Purpose Instant Adhesives can be expected to have a shelf life of one year. Lower temperatures cause increased viscosity of a temporary nature and also will cause water to condense on the container. Therefore, containers stored at low temperatures should be allowed to return to room temperature before opening so that water does not come in contact with the adhesive and cause adhesive gelation. Shelf Life Temperature (°F) 140 to 176, 39 Shelf Life (mon) 12
Best Practices for 3M SB30 Rite-Lok Cyanoacrylate
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.
Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use.
Ensure that parts are clean, dry, and free from oil and grease.
Rite-Lok™ Activators may be required if there are gaps or porous surfaces. If substrates have low surface energy plastics (e.g., polyethylene, polypropylene), or if substrates have acidic surfaces (e.g., paper and leather).
Bond speed is typically very fast so ensure that parts are properly aligned before dispensing.
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.
Full bond strength will typically be achieved within a 24 hour cure time.
3M™ Activators may be used where cure speed needs to be accelerated. However, the use of an activator can reduce the final bond strength by up to 30%.
Low humidity or low temperature conditions will slow down the cure rate.
After curing, Rite-Lok™ General Purpose Instant Adhesive bonds are 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.
Cyanoacrylate bond resistance to most oils and solvents is excellent. Cyanoacrylates are not resistant over time to high levels of moisture or humidity.
