Enamel Paint
Enamel paint is paint that air-dries to a hard, usually glossy, finish, used for coating surfaces that are outdoors or otherwise subject to hard wear or variations in temperature; it should not be confused with decorated objects in "painted enamel", where vitreous enamel is applied with brushes and fired in a kiln. The name is something of a misnomer, as in reality most commercially available enamel paints are significantly softer than either vitreous enamel or stoved synthetic resins, and are totally different in composition; vitreous enamel is applied as a powder or paste and then fired at high temperature. There is no generally accepted definition or standard for use of the term "enamel paint", and not all enamel-type paints may use it. Paint Typically the term "enamel paint" is used to describe oil-based covering products, usually with a significant amount of gloss in them, however recently many latex or water-based paints have adopted the term as well. The term today means " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Vinyl Group
In organic chemistry, a vinyl group (abbr. Vi; IUPAC name: ethenyl group) is a functional group with the formula . It is the ethylene (IUPAC name: ethene) molecule () with one fewer hydrogen atom. The name is also used for any compound containing that group, namely where R is any other group of atoms. An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as ''vinyl''. Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups. (A styrenic crosslinker with two vinyl groups is called '' divinyl benzene''.) Vinyl polymers Vinyl groups can polymerize with the aid of a radical initiator or a catalyst, forming vinyl polymers. Vinyl polymers contain no vinyl groups. Instead they are saturated. The following table gives some examples of vinyl polymers. Synthesis and reactivity Vinyl derivatives are alke ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) is a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane term does not refer to the single type of polymer but a group of polymers. Unlike polyethylene and polystyrene, polyurethanes can be produced from a wide range of starting materials resulting in various polymers within the same group. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and polyurethane laminate (PUL). Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting a polymeric isocyanate with a polyol. Since a ...

Nail Enamel
Nail polish (also known as nail varnish in British English or nail enamel) is a lacquer that can be applied to the human fingernails or toenails to decorate and protect the nail plates. The formula has been revised repeatedly to enhance its decorative properties, to be safer for the consumer to use, and to suppress cracking or peeling. Nail polish consists of a mix of an organic polymer and several other components that give it colors and textures. Nail polishes come in all color shades and play a significant part in manicures and pedicures. History Nail polish originated in China and dates back to 3000 BCE. Around 600 BCE, during the Zhou dynasty, the royal house preferred the colors gold and silver. However, red and black eventually replaced these metallic colors as royal favorites. During the Ming dynasty, nail polish was often made from a mixture that included beeswax, egg whites, gelatin, vegetable dyes, and gum arabic. In Egypt, the lower classes painted their nails ...

Testor Corporation
Testor Corporation (or Testors) is an American manufacturer of tools and accessories for scale model kits. The business is based in Rockford, Illinois, and is part of RPM International. It was founded in 1929 and its products are made in the US and marketed to customers worldwide. The Testors' line of products include enamel paints, acrylic paints, aerosol paints, adhesives, brushes, cutting tools, commercialised under the Testors, Model Master, Spray Chalk, and Testors Craft brands. History Beginnings Axel Karlson had been producing a product known as "Karlsons Klister" (''klister'' being Swedish for glue), which was originally intended for use in the repair of women's stockings, but had quickly found use in other applications as well. In February 1929, Karlson convinced Nils F. Testor (1903–1967), then the manager of an F. W. Woolworth store in the Swedish district of Rockford, Illinois, to serve as office manager of his new enterprise. It was a relatively risky move ...

Humbrol
Humbrol Limited is a British brand and former manufacturer of paints, solvents, and other accessories for scale model kits and toys. In the past, Humbrol produced under its own brand and the Airfix, Sky Marks, Young Scientist, 1st Gear, High Speed and W. Britain brands. In 2006, the company entered administration, but later the same year was acquired by Hornby plc, who has since re-launched the brand. History Humbrol was founded in Kingston upon Hull as the "Humber Oil Company" in 1919. After supplying oil for bicycles the company produced black paint for renovating them and then a range of twelve colours. During the 1950s and 1960s, Gerald Barton turned Humber Oil Company into "Humbrol" which developed a range of model paints and other modelmaking paraphernalia. From 1967 to 1989 the company produced a Humbrol Authentic Colours range that was not only aimed at modellers but specifically reproduced historic colours, such as RAF Duck Egg Blue, ''Luftwaffe'' Dunkelgrun or ...

Model Building
Model building is a hobby and career that involves the creation of physical models either from kits or from materials and components acquired by the builder. The kits contain several pieces that need to be assembled in order to make a final model. Most model-building categories have a range of common scale model, scales that make them manageable for the average person both to complete and display. A model is generally considered physical representations of an physical object, object and maintains accurate relationships between all of its aspects. The model building kits can be classified according to skill levels that represent the degree of difficulty for the hobbyist. These include skill level 1 with snap-together pieces that do not require glue or paint; skill level 2, which requires glue and paint; and, skill level 3 kits that include smaller and more detailed parts. Advanced skill levels 4 and 5 kits ship with components that have extra-fine details. Particularly, level 5 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rotproofing
Rot-proof or rot resistant is a condition of preservation or protection, by a process or treatment of materials used in industrial manufacturing or production to prevent biodegradation and chemical decomposition. Decomposition is a factor in which organic matter breaks down over time. It is commonly caused by fungus, mold or mildew. There are natural conditions where the environment is inhospitable to animals, bacteria and fungus, for example in high altitude and the freezing subzero temperatures of the Arctic and Antarctic, which creates a similar suspension. The proofing of materials may also prevent dry rot and wet rot. See also {{Wiktionary, rotproof, rot * Dust resistant *Fireproofing *Rustproofing * Thermal resistant *Toughness *Waterproofing Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resists the ingress of water under specified conditions.

Exhaust Pipe
An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of the following: *Cylinder head and exhaust manifold *A turbocharger to increase engine power. *A catalytic converter to reduce air pollution. *A muffler (North America) / silencer (UK/India), to reduce noise. Design criteria An exhaust pipe must be carefully designed to carry toxic and noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with poisonous exhaust gases such as hydrocarbons, carbon monoxide and nitrogen oxides, if they are not properly vented to the outdoors. Also, the gases from most machines are scorching; the pipe must be heat-resistant and not pass through or near anything that can burn or be damag ...

Brake Calipers
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc (sometimes called a rakerotor) to create friction. There are two basic types of brake pad friction mechanisms: abrasive friction and adherent friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into heat, which must be dissipated to the environment. Hydraulically actuated disc brakes are the most commonly used mechanical device for slowing motor vehicles. The principles of a disc brake apply to almost any rotating shaft. The components include the disc, master cylinder, and caliper, which contain at least one cylinder and two brake pads on both sides of the rotating disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated similarly to a modern disc-brake sys ...

Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ...

Lacquer
Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity. Asian lacquerware, which may be called "true lacquer", are objects coated with the treated, dyed and dried sap of ''Toxicodendron vernicifluum'' or related trees, applied in several coats to a base that is usually wood. This dries to a very hard and smooth surface layer which is durable, waterproof, and attractive in feel and look. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved lacquer, carved, as well as maki-e, dusted with gold and given other further decorative treatments. In modern techniques, lacquer means a range of clear or pigmented coatings that dry by solvent evaporation to produce a hard, durable finish. The finish can be of any sheen level from ultra wikt:matte, matte to high Gloss (material appearance), glos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
