Best Practices for 3M MC100 Rite-Lok Cyanoacrylate
-
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.
Ensure that parts are clean, dry, and free from oil and grease.
-
Application
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.
-
Curing
Full bond strength will typically be achieved within a 24 hour cure time.
Low humidity or low temperature conditions will slow down the cure rate.
After curing, 3M™ Scotch-Weld™ Metal 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. 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.
