![]() The tapes left gummy residue that ruined the car's finish. The tape that painters used either didn't seal effectively or stuck so tightly that it peeled the paint. At the auto shops, Drew watched painters struggle to seal off areas for the two-color painting process. While on a delivery in 1923, he noticed that the auto shops had a problem.Īt the time, two-tone paint jobs were very popular. He was hired to take trial samples of 3M products to auto shops, which used the sandpaper to prepare cars for painting. Drew, then an engineering student, had been putting himself through school by playing the banjo in several Twin Cities dance bands. When it put out a call for new engineers to join the company, Richard Drew wrote to ask for the job. By 1920 the company had developed some of the best sandpapers in the world. Minnesota Mining and Manufacturing (3M) was founded in Two Harbors in 1902. 3M's Scotch-brand masking tape and cellophane tape were small inventions that started a consumer revolution. Soon the sandpaper company invented a line of products that changed household life around the world. Because of the property of the adhesive though, this kind of tape is not ideal for strong bonds where significant weight or pulling forces will be applied.When 3M began doing business in 1902, it made sandpaper. It's also gentle enough to use on paper, particularly wrapping paper, allowing it to be pulled off without tearing.Īnd the matte finish blends in on whatever surface you use it on. Or foiling screen watching siblings in Mario Kart. Part of the "magic" is you can apply it to monitor screens, windows, or porcelain and it won't leave behind residue, so it can be ideal for adhering something to a screen or finished porcelain object temporarily if required, such as covering a vase or other finished piece with a layer of packing paper to prevent dirt and casual marking before adhering further layers of wrappings. It's "magic" in that its adhesive is strongly bonded to the tape itself and takes a very long time to leave residue behind on any surface (if it leaves any behind at all before failing). Scotch tape (also Scotch Magic tape) is typically not an ideal tape for packaging. I'll echo the hive mind, in Canada we call that packing tape since it's broad and adequately seals boxes when packing. r/languagelearning for general discussion about second languages. r/languagebuds for finding people to practice your English with. r/Eloquent for learning to speak in a more cultured and sophisticated manner.
