Who invented the 3M Post It note?

Spencer Silver
They became one of the most ubiquitous office products ever conceived.

He was 80.

What is the adhesive on post it notes?

Post-it® Notes are mainly composed of a smooth and opaque paper coated with one or several stripes of 3M unique repositionable adhesive. The ability to stick and re-stick indefinitely a Post-it® Note is given by a Pressure Sensitive Acrylate (PSA).

How the sticky note was invented?

In 1968, Dr. Spencer Silver, a scientist at 3M in the United States, attempted to develop a super-strong adhesive. Instead, he accidentally created a “low-tack”, reusable, pressure-sensitive adhesive.

Why was the post-it note so successful?

The notes became an overnight success. “It was always a self-advertising product because customers would put the notes on documents they sent to others, arousing the recipient’s curiosity. Silver said, that like many ground-breaking innovations, theirs was a product nobody thought they needed until they did.

The original notes’ pale yellow color was chosen by chance, from the color of the scrap paper used by the lab next door to the Post-It team.

Did 3M invent sticky notes?

How did Art Fry invent the post it note?

That’s how Fry learned about 3M researcher Spencer Silver’s “failed” (not-sticky-enough) adhesive. Fry used the adhesive to create his hymnal bookmark. After using one of his hand-made Post-it® Notes to make a notation on an internal report, Fry found himself inundated with requests from co-workers for more of that sticky notepaper.

When did Stephen Fry invent the 3M adhesive?

The item for which he is best known was born in 1974. That year, Fry attended a seminar was given by another 3M scientist, Spencer Silver, on a unique adhesive Silver had developed in 1968. Silver’s innovation had an unusual molecular structure, yielding an adhesive strong enough to cling to objects but weak enough to allow for a temporary bond.

When did 3M start making post it notes?

A 3M product developed in the mid 1970’s, Post-it® Notes have become an office-supply staple and are now produced in myriad sizes and colors. But how do they work?
