7. Keep parts from moving until handling strength is reached. Contact pressure is
8. Excess uncured adhesive can be cleaned up with ketone type solvents.*
Adhesive Coverage: A 0.005 in. thick bondline will typically yield a coverage of
3. For maximum bond strength, apply product evenly to both surfaces to be joined.
4. Application to the substrates should be made within 90 minutes. Larger quantities
5. Join the adhesive coated surfaces and allow to cure at 60°F (16°C) or above until
6. The following times and temperatures will result in a full cure:
These products may be applied by spatula, trowel or flow equipment.
Two-part mixing/proportioning/dispensing equipment is available for intermittent or
production line use. These systems are ideal because of their variable shot size and
flow rate characteristics and are adaptable to many applications.
For high 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 directly depends on the required bond strength and the
environmental aging resistance desired by user.
The following cleaning methods are suggested for common surfaces.
Steel or Aluminum (Mechanical Abrasion)
1. Wipe free of dust with oil-free solvent such as acetone or alcohol solvents.*
2. Sandblast or abrade using clean fine grit abrasives (180 grit or finer).
3. Wipe again with solvents to remove loose particles.
4. If a primer is used, it should be applied within 4 hours after surface preparation.
*When using solvents, extinguish all ignition sources, including pilot lights, and
follow the manufacturer’s precautions and directions for use. Use solvents in
accordance with local regulations.

necessary. Maximum shear strength is obtained with a 3-5 mil bond line.
Maximum peel strength is obtained with a 17-25 mil bond line.
