adhesives for use in the aerospace industry in building planes. Instead of a
super-strong adhesive, though, he accidentally created an incredibly weak,
pressure-sensitive adhesive agent called Acrylate Copolymer Microspheres.
This adhesive did not interest 3M management, as it was seen as too
weak to be useful, but nonetheless had two interesting features. First, when
stuck to a surface, the adhesive could be peeled away without leaving any
residue. Specically, acrylic spheres only stick well to surfaces where they
are tangent to the surface, thus allowing weak adhesion to be peeled easily.
Second, the adhesive is re-usable, thanks to the spheres’ incredible strength
and resistance to breaking, dissolving, or melting. Despite these notable fea-
tures, no one, not even Silver himself, could devise a good marketable use.
Thus, even with Silver’s promotion to various 3M employees for 5 years, the
adhesive was shelved.
Finally, in 1973, when Geoff Nicholson was named 3M’s Products
Laboratory Manager, Silver approached him immediately with the adhesive
and provided samples to play with. Silver also suggested his best idea for
adhesive: a bulletin board with the adhesive sprayed on. One could then
stick pieces of paper to the bulletin board without tacks, tape, or the like;
the paper subsequently could be easily removed without any residue left
on the sheets. While a decent idea, the sticky bulletin board was not seen
by Nicholson as sufciently protable, principally because annual bulletin
board sales are low.
Enter the second accident, this one courtesy of chemical engineer
Arthur Fry. Fry was a 3M Product Development Engineer, and was famil-
iar with Silver’s adhesive thanks to attending one of Silver’s seminars.
Fry sung in a church choir in St. Paul, Minnesota, and while he sang, the
page marker kept falling out of the hymnal. Fry eventually had a stroke of
genius—he used Silver’s adhesive to keep the slips of paper in the hymnal.
Fry then suggested to Nicholson and Silver that they were using the adhe-
sive backwards. That is, instead of sticking the adhesive to the bulletin
board, they should “put it on a piece of paper and then we can stick it to
anything,” Fry exclaimed.
Doing so proved easier said than done, in terms of practical application.
Although it was easy enough to get the adhesive onto the paper, the adhe-
sive would often detach from the paper and stay on the object the paper
was stuck to. Silver’s bulletin boards did not suffer from the problem as he
fabricated the boards to bond better with the board than with the paper.
Two other 3M employees now entered the scene: Roger Merrill and Henry
Courtney. Merrill and Courtney were tasked with devising a coating that
