"MDF is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure.[1] MDF is generally more dense than plywood. It is made up of separated fibres, but can be used as a building material similar in application to plywood. It is stronger, and more dense, than particle board.[2]"

    * adobe

"""
Adobe (/əˈdoʊbi/ (listen);[1] Spanish pronunciation: [aˈðoβe]) is a building material made from earth and organic materials. Adobe is Spanish for 'mudbrick', but in some English-speaking regions of Spanish heritage the term is used to refer to any kind of earthen construction. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. 
"""
https://en.wikipedia.org/wiki/Adobe


    * super adobe / hyperadobe

https://en.wikipedia.org/wiki/Superadobe

http://www.earthbagbuilding.com/articles/hyperadobe.htm
"""
From Superadobe, created by the Iranian Nader Khalili, was developed  Hyperadobe by Fernando Pacheco of EcoOca in Brazil. The big difference between the two is that Superadobe uses woven polypropylene bags with barbed wire between the layers, whereas Hyperadobe uses a knit raschel, the same material used in packaging fruit. This leads to less cost compared to the poly bags. 
"""



    * bitumen/asphalt
$$$$ category
"""
Asphalt, also known as bitumen (UK: /ˈbɪtjʊmɪn/, US: /bɪˈtjuːmən, baɪ-/),[1] is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch.
[...]
The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.[4]
In material sciences and engineering, the terms "asphalt" and "bitumen" are often used interchangeably to mean both natural and manufactured forms of the substance, although there is regional variation as to which term is most common
"""






CEMENTS

"""
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together
[...]
Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as non-hydraulic or hydraulic respectively, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). 
"""

    * non-hydraulic cement

"""
Non-hydraulic cement does not set in wet conditions or under water. Rather, it sets as it dries and reacts with carbon dioxide in the air. It is resistant to attack by chemicals after setting. 
"""


    * hydraulic cement

"""
Hydraulic cements (e.g., Portland cement) set and become adhesive due to a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in water and safe from chemical attack. This allows setting in wet conditions or under water and further protects the hardened material from chemical attack. The chemical process for hydraulic cement was found by ancient Romans who used volcanic ash (pozzolana) with added lime (calcium oxide). 
"""


    * magnesium cement


    * concrete

"""
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, limebased cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual resemblance to Portland stone).[2][3] Many other non-cementitious types of concrete exist with other methods of binding aggregate together, including asphalt concrete with a bitumen binder, which is frequently used for road surfaces, and polymer concretes that use polymers as a binder.

"""
Spray foam is a chemical product created by two materials, isocyanate and polyol resin, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place. This expansion makes it useful as a specialty packing material which forms to the shape of the product being packaged and produces a high thermal insulating value with virtually no air infiltration.

"""
Polyurea and polyurethane are copolymers used in the manufacture of spandex, which was invented in 1959. 
"""

"""
Polyurea has become a preferred long term solution for narrow boats. The traditional coating with bitumen, known as "blacking" is being replaced with the practice of polyurea coatings. The clearest advantage is that it is not necessary to reapply a coat every 3–4 years. It is thought that polyurea coatings last 25–30 years.[5]

aromatic or aliphatic (?)
"""
Aromatic is generally used for black and darker colors, and is the least expensive option. 
Aliphatic can be a better option for colors because its color is more stable over time in ultraviolet light. It is produced with pure polyurethane, which drives up the cost approximately 35%. Aliphatic materials can be sprayed in a wide variety of colors, including metallic finishes.

"""
Insulative paints, or insulating paints, claim to use a technology where a broad spectrum thermally reflective coating is applied to a specific type of micro-spheres to block heat radiation in a much larger or broader range of thermal energy (heat) to dissipate heat rapidly. This type of coated thermally reflective material (coated micro-sphere) reduces heat transfer through the coating with 90% of solar infrared radiation and 85% of ultraviolet radiation being radiated back from the coated surface.[citation needed]

    * tar

sometimes confused with bitumen/asphalt:
    "Colloquially, various forms of asphalt are sometimes referred to as "tar", as in the name of the La Brea Tar Pits, although tar is a different material.[5]"

https://en.wikipedia.org/wiki/Tar
"""
Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat.[1]
[...]
Tar was used as seal for roofing shingles and tar paper and to seal the hulls of ships and boats. For millennia, wood tar was used to waterproof sails and boats, but today, sails made from inherently waterproof synthetic substances have reduced the demand for tar. Wood tar is still used to seal traditional wooden boats and the roofs of historic, shingle-roofed churches, as well as painting exterior walls of log buildings. Tar is also a general disinfectant.

    * thin film

"""
A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering. Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, Integrated passive devices, LEDs, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage (thin-film batteries). It is also being applied to pharmaceuticals, via thin-film drug delivery. A stack of thin films is called a multilayer. 
"""


    * shellac (natural lacquer)

"""
Shellac (/ʃəˈlæk/)[1] is a resin secreted by the female lac bug on trees in the forests of India and Thailand. It is processed and sold as dry flakes and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. Phonograph and 78 rpm gramophone records were made of it until they were replaced by vinyl long-playing records from the 1950s onwards. 
From the time it replaced oil and wax finishes in the 19th century, shellac was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the 1920s and 1930s.

Titanium: The fast-and-light choice

Titanium is 45% lighter than steel and stronger than aluminum. It is the lightest cookware material you can buy before you must sacrifice strength. It’s also corrosion-resistant, offering great durability.
Titanium pots are ideal primarily for boiling water because they can be made with thin walls, and transfer heat very quickly. Like stainless steel pots, they tend to develop hot spots, making them less than ideal for cooking real meals. Titanium is favored by the truly fast-and-light crowd, who count their grams and opt for quick boil-only meals after a long, exhausting day.

The radiant barrier may be one or two sided. One sided radiant barrier may be attached to insulating materials, such as polyisocyanurate, rigid foam, bubble insulation, or oriented strand board (OSB).

https://en.wikipedia.org/wiki/Thread-locking_fluid
"""
Thread-locking fluid or threadlocker is a thin, single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion. 
Most thread-locking formulas are methacrylate-based and rely on the electrochemical activity of a metal substrate to cause polymerization of the fluid. Thread-locking fluid is thixotropic, which allows it to flow well over time, yet still resist shocks and vibrations. It can be permanent or removable; in the latter case, it can be removed with heat, for example. Typically, brands are color-coded to indicate strength and whether they can be removed easily or if they require heat for removal.

* gelcoat
https://en.wikipedia.org/wiki/Gelcoat
"""
Gelcoat or 'Gel Coat' is a material used to provide a high-quality finish on the visible surface of a fibre-reinforced composite. The most common gelcoats are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins which are applied to moulds in the liquid state. They are cured to form crosslinked polymers and are subsequently backed with thermoset polymer matrix composites which are often mixtures of polyester resin and fiberglass, or epoxy resin which is most commonly used with carbon fibre for higher specific strength. 
[...]
In addition to any pigment a gelcoat will, if necessary, contain a thixotropic additive to assist its tenacity to vertical portions of the mould whilst it cures.

"""
You can't gelcoat or paint on a wax (styrene monomer) filled surface resin. The way the wax works is to float to the surface and create a seal from the air to let the gelcoat cure. If you abrade the wax off afterwards you can re gel or paint. Better to have a fully wax free surface to paint, no contamination, but it will still need some abrasion. 
"""

https://www.thehulltruth.com/boating-forum/306004-wax-no-wax-gel-coat.html
"""
Miktyri, you are right about the wax content in gelcoat. Gelcoat will not harden if it is exposed to the air, the wax rises to the surface and seals it during the curing process. No Wax is a good choice if you are laying up multiple coats, you don't have to remove the wax between coats. If you can seal the repair by placing a sheet of mylar or wax paper over the patch then the no-wax will work but if you can't you need to have the wax in the gelcoat to get it to cure. When I buy Gelcoat I normally get the no-wax varity and then get some of the wax additive so that I can make my choice when mixing up for the patch.

However, they are relatively expensive when compared with similar fibers, such as glass fibers or plastic fibers.[citation needed]

"""
Alubutyl is the trade name for a self-adhesive film, which consists of self-adhesive butyl rubber and an aluminum carrier film . 
use
Alubutyl is used in a similar way to self-adhesive bitumen sealing strips and sheets for sound insulation in vehicles (anti-drumming mats) and behind sheet metal parts such as sinks, housing parts of large household appliances. Similar products with foil or fleece as carrier material are used for gluing and sealing joints in construction or for repairing gutters. 
This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.
Alubutyl insulates a little better than bitumen, is lighter and easier to work with. However, bitumen is significantly cheaper to manufacture than alubutyl. 
The sound-absorbing effect is based on the mass (lowering the natural resonance frequency) and the plastic, vibration-damping consistency (avoidance of partial vibrations).

https://en.wikipedia.org/wiki/Warp_knitting
"""
Raschel knits do not stretch significantly and are often bulky; consequently, they are often used as an unlined material for coats, jackets, straight skirts and dresses.  These fabrics can be made out of conventional or novelty yarns which allows for interesting textures and designs to be created.[5]  The qualities of these fabrics range from "dense and compact to open and lofty [and] can be either stable or stretchy, and single-faced or reversible.[5]  The largest outlet for the Raschel warp knitting machine is for lace fabric and trimmings. Raschel knitting is also used in outdoors and military fabrics for products such as backpacks. It is used to provide a ventilated mesh next to the user's body (covering padding) or mesh pockets and pouches to facilitate visibility of the contents (MIL-C-8061).

The warp knitting process is also being used to create biotextiles.  For example, a warp knitted polyester cardiac support device has been created to attempt to limit the growth of diseased hearts by being installed tightly around the diseased heart.  Current research on animals "have confirmed that … the implantation of the device reverses the disease state, which makes this an alternative innovative therapy for patients who have side effects from traditional drug remedies".[14]

Construction: Joist

"a length of timber or steel supporting part of the structure of a building, typically arranged in parallel series to support a floor or ceiling."

"""
A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm. Joists are often doubled or tripled, placed side by side, where conditions warrant, such as where wall partitions require support. 
Joists are either made of wood, engineered wood, or steel, each of which have unique characteristics. Typically, wood joists have the cross section of a plank with the longer faces positioned vertically. However, engineered wood joists may have a cross section resembling the Roman capital letter "I"; these joists are referred to as I-joists. Steel joists can take on various shapes, resembling the Roman capital letters "C", "I", "L" and "S".
