Best Practices for 3M SA24 Rite-Lok Structural Adhesive
For optimum strength surfaces should be clean and free of all surface contaminants including paint, oxide films, oils, dust, mold release agents, etc. However, the amount of surface preparation depends on the required bond strength and the environmental 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.
For best results, ensure that parts are clean, dry, and free from oil and grease. However, bonds can still be achieved on 'as received' or slightly oily parts.
Rite Lok™ structural Acrylic Activator AC380D should be applied to the less absorbent (less porous) substrate. If necessary, it may be applied to both bonding surfaces.
Rite lok™ structural Acrylic Adhesive should be applied to the more absorbent (more porous) surface in beads or spread as a thin layer using a flat edge.
The two parts should then be brought together and clamped or held in position to achieve best results.
Due to its anaerobic nature, any Rite-Lok™ Structural Acrylic Adhesive squeezed outside of the joint will remain soft.
Full bond strength will typically be achieved within a 24 hour cure time.
