Aquapel (glass Treatment)
Aquapel is a rain repellent glass treatment created by PPG Industries. It is a competitor to the more widely known Rain-X product, but unlike Rain-X, is not a silicone-based compound. Aquapel Glass Treatment consists of fluorine, fluorinated compounds called silanes, fluoroalkylsilanes which create a chemical bond with glass surfaces, causing water to bead up and roll off. Because of this chemical bond with glass, Aquapel is reported to last much longer than silicone-based rain repellents. Aquapel has gained popularity in microfluidic based biochemistry, specifically the Drop-Seq method pioneered by the McCarroll lab at Harvard.

PPG Industries
PPG Industries, Inc. is an American Fortune 500 company and global supplier of paints, coatings, and specialty materials. With headquarters in Pittsburgh, Pennsylvania, PPG operates in more than 70 countries around the globe. By revenue it is the largest coatings company in the world followed by AkzoNobel. It is headquartered in PPG Place, an office and retail complex in downtown Pittsburgh, and is known for its glass facade designed by Postmodern architect Philip Johnson. History 19th century Pittsburgh Plate Glass Company was founded in 1883 by Captain John Baptiste Ford and John Pitcairn, Jr., at Creighton, Pennsylvania. Based in Creighton, Pennsylvania (about 20 miles north of Pittsburgh along the Allegheny River), PPG soon became the United States' first commercially successful producer of high-quality, thick flat glass using the plate process. PPG was also the world's first plate glass plant to power its furnaces with locally produced natural gas, an innov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rain-X
Rain-X is a synthetic hydrophobic surface-applied product that causes water to bead up and run off surfaces, most commonly used on glass automobile surfaces. The brand has since been extended to a range of automotive and surface care products, including wiper blades. Products The Rain-X brand includes seven categories of products: wiper blades, glass and windshield treatments, plastic cleaners, windshield washer fluid, car washes, car wax, and bug and tar washes. Rain-X Online Protectant was introduced to commercial carwashes in 2005. It is a water-based compound that is applied to the entire car's surface, working much like consumer grade Rain-X products. Competing products include Pittsburgh Glass Works' (formerly of PPG) Aquapel. Uses Due to its general water-repellent properties, the original Rain-X formulation is used in a wide variety of consumer, commercial and industrial settings. The primary use of Rain-X is for automotive applications. Commercially sold "Original G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silicone
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk. Chemistry More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common siloxan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorine
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative reactive element, it is extremely reactive, as it reacts with all other elements except for the light inert gases. Among the elements, fluorine ranks 24th in universal abundance and 13th in terrestrial abundance. Fluorite, the primary mineral source of fluorine which gave the element its name, was first described in 1529; as it was added to metal ores to lower their melting points for smelting, the Latin verb meaning 'flow' gave the mineral its name. Proposed as an element in 1810, fluorine proved difficult and dangerous to separate from its compounds, and several early experimenters died or sustained injuries from their attempts. Only in 1886 did French chemist Henri Moissan isolate elemental fluorine using low-temperature electrolysis, a process still employed for modern pr ...

Silanes
Silanes refers to diverse kinds of charge-neutral silicon compounds with the formula . The R substituents can any combination of organic or inorganic groups. Most silanes contain Si-C bonds, and are discussed under organosilicon compounds. Examples: *Silane , the parent. *Binary silicon-hydrogen compounds (which are sometimes called silanes also) includes silane itself but also compounds with Si-Si bonds including disilane and longer chains. *Silanes with one, two, three, or four Si-H bonds are called hydrosilanes. Silane itself is the parent member. Examples: triethylsilane () and triethoxysilane (). *Polysilanes are organosilicon compounds with the formula . They include all binary silicon-hydrogen compounds except the parent, although these tend to be less useful because they are fragile. Attracting more interest, are the organic derivatives such as polydimethylsilane and dodecamethylcyclohexasilane *Chlorosilanes have Si-Cl bonds. Examples: trichlorosilane () and tetrachlo ...

Chemical Bond
A chemical bond is a lasting attraction between atoms or ions that enables the formation of molecules and crystals. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds, or through the sharing of electrons as in covalent bonds. The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bonds" such as covalent, ionic and metallic bonds, and "weak bonds" or "secondary bonds" such as dipole–dipole interactions, the London dispersion force and hydrogen bonding. Strong chemical bonding arises from the sharing or transfer of electrons between the participating atoms. Since opposite electric charges attract, the negatively charged electrons surrounding the nucleus and the positively charged protons within a nucleus attract each other. An electron positioned between two nuclei will be attracted to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitu ...

Glass Trademarks And Brands
Glass is a non-crystalline, often transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and eyeglasses, are so commonly made of silicate-based glass that they are simply called by the name of the material. Despite bei ...
