help Richard Drew FAQ

Why did Richard Drew invent masking tape?

While working for 3M, Drew saw automobile painters struggle to create clean two-tone paint lines without damaging fresh paint. He developed a pressure-sensitive paper masking tape for them in 1925.

Did Richard Drew also invent transparent tape?

Yes. Drew later helped develop transparent cellophane tape, which 3M introduced under the Scotch name around 1930.

Was Richard Drew a trained chemist when he joined 3M?

No. He left the University of Minnesota without completing a degree and joined 3M as a laboratory technician, initially testing sandpaper.

What is the difference between Drew's masking tape and Scotch transparent tape?

Masking tape used a paper backing that could be removed after painting, while transparent tape used clear cellophane for sealing and repairs. Both were early modern pressure-sensitive tapes developed through Drew's work at 3M.
