Post-it
A Post-it note (or sticky note) is a small piece of paper with a re-adherable strip of glue on its back, made for temporarily attaching notes to documents and other surfaces. A low-adhesion, tack pressure-sensitive adhesive allows the notes to be easily attached, removed and even re-posted elsewhere without leaving residue. The Post-it's signature adhesive was discovered accidentally by a scientist at 3M. Originally small yellow squares, Post-it Notes and related products are available in various colors, shapes, sizes and adhesive strengths. As of 2024, there are at least 28 documented colors of Post-it notes. 3M's Post-it has won several awards for its design and innovation. Post-its are versatile and can be used in various settings for various purposes. They are commonly used in classrooms and workplaces but can also be found in art, media, and social media. Post-its have also been used as tools for public engagement and persuasion. Although 3M's patent expired in 1997, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Per- And Polyfluoroalkyl Substances
Per- and polyfluoroalkyl substances (also PFAS, PFASs, and informally referred to as "forever chemicals") are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million known such chemicals according to PubChem. PFAS came into use with the invention of Teflon in 1938 to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. They are now used in products including waterproof fabric such as Nylon, yoga pants, carpets, shampoo, feminine hygiene products, mobile phone screens, wall paint, furniture, adhesives, food packaging, firefighting foam, and the insulation of electrical wire. PFAS are also used by the cosmetic industry in most cosmetics and personal care products, including lipstick, eye liner, mascara, foundation, concealer, lip balm, blush, and nail polish. Many PFAS such as PFOS and PFOA pose health and environmental concerns because they are persi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotchgard
Scotchgard is a 3M brand of stain repellent and durable water repellent applied to fabrics, upholstery, and carpets to protect them from stains. Scotchgard products typically are based on organofluorine chemicals dissolved in a petroleum distillate solvent. History In 1938 Roy J. Plunket, a recent hire at DuPont, discovered polytetrafluoroethylene (or Teflon)—a fluoropolymer that led to the invention of synthetic rubber. His early discovery led 3M scientists to develop the formula for Scotchgard, discovered by accident in 1953 when Joan Mullan—a 3M lab technician—spilled a few drops of a fluorochemical liquid destined for rubber jet fuel hoses onto her tennis shoes. Despite common cleaning methods, the coating resisted removal. 3M chemists, Patsy Sherman and Samuel Smith, continued work on the properties of fluorochemicals, culminating in products that could treat most fabrics with a stain resistant coating. They jointly hold 13 patents regarding fluorochemical po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nexcare
Nexcare is 3M's personal health care brand. The brand competes with Johnson & Johnson's Band-Aid brand in the adhesive bandage and first aid market.

In 2018, as part of an ad campaign for the brand called "Tough Love" intended to prompt parents not to be over-cautious about their children's play, 3M signed ''American Ninja Warrior'' contestant Jessie Graff as a spokeswoman. The brand is also a sponsor of the American Red Cross The American National Red Cross is a Nonprofit organization, nonprofit Humanitarianism, humanitarian organization that provides emergency assistance, disaster relief, and disaster preparedness education in the United States.

Paint Protection Film
Paint protection film (PPF, also called clear bra, clear film or clear paint film) is a thermoplastic Polyurethane, urethane often self-healing film applied to painted surfaces of a new or used car in order to protect the paint from stone chips, bug splatters, and minor abrasions. This film is also used on airplanes, RVs, cell phones, electronics, screens, motorcycles, and many other areas. Paint protection film is OEM approved by virtually all car manufacturers. Paint protection film is installed on a limited basis by manufacturers on various pieces of cars at the factory (e.g. the rear arches of Porsches). This film is most commonly applied to high-impact areas of vehicles which include: the hood, the front fenders, the front bumper, the side view mirrors, the rocker panels, the lower portion of the doors, and the rear guards behind the rear wheels. This is because these specific panels are the most susceptible to damage from rock chips and other forms of road debris from other ...

Sandpaper
upright=1.35, Sheets of sandpaper with different grit sizes (40 (coarse), 80, 150, 240, 600 (fine)) Sandpaper, also known as coated abrasive or emery paper, is a type of material that consists of sheets of paper or cloth with an abrasive substance glued to one face. In the modern manufacture of these products, sand and glass have been replaced by other abrasives such as aluminium oxide or silicon carbide. It is common to use the name of the abrasive when describing the paper, e.g. "aluminium oxide paper", or "silicon carbide paper". There are many varieties of sandpaper, with variations in the paper or backing, the material used for the grit, grit size, and the bond. Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, whether to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing). The grit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adhesive
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, and welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. Adhesives are typically organized by the method of adhesion followed by ''reactive'' or ''non-reactive'', a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
