Paint Protection Film
Paint protection film (PPF, also called clear bra, clear film or clear paint film) is a thermoplastic 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 vehicles, dri ...

Perfluorooctanoic Acid
Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8 carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock. PFOA is considered a surfactant, or fluorosurfactant, due to its chemical structure, which consists of a perfluorinated, ''n''-octyl "tail group" and a carboxylate "head group". The head group can be described as hydrophilic while the fluorocarbon tail is both hydrophobic and lipophobic. The tail group is inert and does not interact strongly with polar or non-polar chemical moieties; the head group is reactive and interacts strongly with polar groups, specifically water. The "tail" is hydrophobic due to being non-polar and lipophobic because fluorocarbons are less susceptible to the London dispersion force than hydrocarbons. PFOA is one of many synthetic organofluorine compounds collectively known as per- and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dividend
A dividend is a distribution of profits by a corporation to its shareholders. When a corporation earns a profit or surplus, it is able to pay a portion of the profit as a dividend to shareholders. Any amount not distributed is taken to be re-invested in the business (called retained earnings). The current year profit as well as the retained earnings of previous years are available for distribution; a corporation is usually prohibited from paying a dividend out of its capital. Distribution to shareholders may be in cash (usually a deposit into a bank account) or, if the corporation has a dividend reinvestment plan, the amount can be paid by the issue of further shares or by share repurchase. In some cases, the distribution may be of assets. The dividend received by a shareholder is income of the shareholder and may be subject to income tax (see dividend tax). The tax treatment of this income varies considerably between jurisdictions. The corporation does not receive a tax deduct ...

The form ''Archibald'' became particularly popular among Peerage of Scotland, Scottish nobility in the later medieval to early modern periods, whence usage as a surname is derived by the 18th century, found especially in Scottish surname, Scotland and later Nova Scotia. Given name English diminutives or hypocorisms include ''Arch (name), Arch, Archy, Archie, and Baldie (nickname)''. Variants include French ''Archambault, Archaimbaud, Archenbaud, Archimbaud'', ...

Sandpaper
upright=1.35, Sheets of sandpaper with different grit sizes (40 (coarse), 80, 150, 240, 600 (fine)). Sandpaper and glasspaper are names used for a type of coated abrasive that consists of sheets of paper or cloth with abrasive material glued to one face. There are many varieties of sandpaper, with variations in the paper or backing, the material used for the grit, grit size, and the bond. 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". 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 size of san ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lucius Pond Ordway
Lucius Pond Ordway (January 21, 1862 – January 10, 1948) was an American businessman prominent in St. Paul whose investments and leadership helped create the modern 3M corporation. Early life Ordway was the son of Aaron Lucius Ordway (1822-1903), a businessman from a family long settled in and near Essex County, Massachusetts, and Frances Ellen Hanson (1831-1873). His father was a coal and iron dealer and salesman during Ordway's childhood, but by 1883 had become a business executive for the wealthy Sayles family of Rhode Island. His uncle John Pond Ordway (1824-1880) was a well-known composer and music publisher of the Civil War era. ("Pond" was the maiden name of their grandmother, Catherine Pond Ordway (1787-1851).) His brother Samuel Hanson Ordway (1860-1934) graduated from Brown University and Harvard Law School and became a prominent New York City lawyer and civil service reformer; he married painter Frances Hunt Throop in 1894.

Anorthosite
Anorthosite () is a phaneritic, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar (90–100%), with a minimal mafic component (0–10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present. Anorthosites are of enormous geologic interest, because it is still not fully understood how they form. Most models involve separating plagioclase crystals based on their density. Plagioclase crystals are usually less dense than magma; so, as plagioclase crystallizes in a magma chamber, the plagioclase crystals float to the top, concentrating there. Anorthosite on Earth can be divided into five types: # Archean-age anorthosites # Proterozoic anorthosite (also known as massif or massif-type anorthosite) – the most abundant type of anorthosite on Earth # Layers within Layered Intrusions (e.g., Bushveld and Stillwater intrusions) # Mid-ocean ridge and transform fault anorthosites # Anorthosite xenoliths in other rocks ...

Corundum
Corundum is a crystalline form of aluminium oxide () typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. Corundum has two primary gem varieties: ruby and sapphire. Rubies are red due to the presence of chromium, and sapphires exhibit a range of colors depending on what transition metal is present. A rare type of sapphire, padparadscha sapphire, is pink-orange. The name "corundum" is derived from the Tamil- Dravidian word ''kurundam'' (ruby-sapphire) (appearing in Sanskrit as ''kuruvinda''). Because of corundum's hardness (pure corundum is defined to have 9.0 on the Mohs scale), it can scratch almost all other minerals. It is commonly used as an abrasive on sandpaper and on large tools used in machining metals, plastics, and wood. Emery, a variety of corundum with no value a ...
