When all the seeds are in place, place a few more drops of medical device grade cyanoacrylate adhesive onto the back of the carrier and then place the gold shell over the plaque with its suture eyelets oriented according to the loading diagram. The example on the right illustrates the different appearance of slots with seeds installed and those that are empty.
Let the cyanoacrylate dry overnight. If the humidity is very low, put a bowl of water near by. The cyanoacrylate glue hardens very quickly when trapped between two surfaces. The reaction is caused by the condensed water vapour on the surfaces. The water comes from the surrounding air, so the air humidity is a factor that affects bonding capabilities.
The curing reaction starts at the surface of the bonded material and develops towards the centre of the bond. Because of this, thick seams or large blobs of glue may harden less satisfactorily than surface-to-surface bonds with good fit. In a thick blob of glue, a polymerisation reaction may stop before it reaches the centre of the blob. A rule of thumb is that seams thicker than 0,25 mm should be avoided. Thick seams will also take longer time to cure.
To remove the glue, soak the plaque, seeds and carrier in a bowl of acetone for about an hour to disolve the glue.
