  2. Roof coating - Wikipedia

    en.wikipedia.org/wiki/Roof_coating

    Typical roof coating dry film thickness vary from paint film thickness (plus or minus 0.075 mm (3 dry mils) to more than 1 mm (40 dry mils). This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the ...

    en.wikipedia.org/wiki/Superhydrophobic_coating

    In contrast, the oxide polystyrene composites are more durable than the gel-based coatings, however the process fof applying the coating is much more involved and costly. Carbon nano-tubes are also expensive and difficult to produce with current technology. Thus, the silica-based gels remain the most economically viable option at present.

  4. Hydroxyapatite - Wikipedia

    en.wikipedia.org/wiki/Hydroxyapatite

    Hydroxyapatite is widely used within dentistry and oral and maxillofacial surgery, due to its chemical similarity to hard tissue. [34] In the future, there are possibilities for using nano-hydroxyapatite for tissue engineering and repair. The main and most advantageous feature of nano-hydroxyapatite is its biocompatibility. [35]

  5. Bituminous waterproofing - Wikipedia

    en.wikipedia.org/wiki/Bituminous_waterproofing

    Replacing the roofing felt on a Scout hall in Wales. Bituminous waterproofing systems are designed to protect residential and commercial buildings.Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous, and waterproof. [1]

  6. Potential applications of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Potential_applications_of...

    The potential of carbon nanotubes was demonstrated in 2003 when room-temperature ballistic transistors with ohmic metal contacts and high-k gate dielectric were reported, showing 20–30x higher ON current than state-of-the-art Si MOSFETs. This presented an important advance in the field as CNT was shown to potentially outperform Si.

  7. Ceramic nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Ceramic_nanoparticle

    Ceramic nanoparticle is more than 85% air and is very light, strong, flexible and durable. The fractal nanotruss is a nanostructure architecture [3] made of alumina, or aluminum oxide. Its maximum compression is about 1 micron from a thickness of 50 nanometers. After its compression, it can revert to its original shape without any structural ...

  8. Asphalt roll roofing - Wikipedia

    en.wikipedia.org/wiki/Asphalt_roll_roofing

    Asphalt roll roofing or membrane is a roofing material commonly used for buildings that feature a low sloped roof pitch in North America. The material is based on the same materials used in asphalt shingles ; an organic felt or fiberglass mat, saturated with asphalt , and faced with granular stone aggregate.

  9. Slot-die coating - Wikipedia

    en.wikipedia.org/wiki/Slot-die_coating

    Slot-die coating is a coating technique for the application of solution, slurry, hot-melt, or extruded thin films onto typically flat substrates such as glass, metal, paper, fabric, plastic, or metal foils.
