  2. Waterproof paper - Wikipedia

    en.wikipedia.org/wiki/Waterproof_paper

    Waterproof paper uses special coatings ( plastic-coated paper) and fibers to enhance durability, dimensional stability, tear resistance and resistance to changing shape or texture when exposed to water. The paper has applications for wet or damp environments, including outdoor, marine, field uses as well as printing applications for similar ...

  3. List of polyurethane applications - Wikipedia

    en.wikipedia.org/wiki/List_of_polyurethane...

    PUR is better than hotmelt or cold glue for most applications. Because of the lack of moisture in the glue, paper with contrary grain direction can be glued without problems. Even printed and supercalendered paper can be bound without problems. It is the most economical glue, with a theoretical application thickness of 0.01 mm.

  4. Superhydrophobic coating - Wikipedia

    en.wikipedia.org/wiki/Superhydrophobic_coating

    A superhydrophobic coating is a thin surface layer that repels water. It is made from superhydrophobic (also known as ultrahydrophobic) materials, and typically cause an almost imperceptibly thin layer of air to form on top of a surface. Droplets hitting this kind of coating can fully rebound. [ 1][ 2] Generally speaking, superhydrophobic ...

  5. Waterproofing - Wikipedia

    en.wikipedia.org/wiki/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 resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. Water-resistant and waterproof often refer to resistance ...

  6. Surface chemistry of paper - Wikipedia

    en.wikipedia.org/wiki/Surface_chemistry_of_paper

    Lastly, plasma coating is where material is coated to the surface in the form of a thin film. Plasma coating can be used to add hydrocarbons to surfaces which can make a surface non-polar or hydrophobic. The specific type of plasma coating used to add hydrocarbons is called plasma enhanced chemical vapor deposition process or PCVD. [7]

  7. Radiation-absorbent material - Wikipedia

    en.wikipedia.org/wiki/Radiation-absorbent_material

    In materials science, radiation-absorbent material ( RAM) is a material which has been specially designed and shaped to absorb incident RF radiation (also known as non-ionising radiation ), as effectively as possible, from as many incident directions as possible. The more effective the RAM, the lower the resulting level of reflected RF radiation.

  8. Polyurethane - Wikipedia

    en.wikipedia.org/wiki/Polyurethane

    This is of particular interest in the area of polyurethane coatings, where light stability is a critical factor and is the main reason that aliphatic isocyanates are used in making polyurethane coatings. When PU foam, which is made using aromatic isocyanates, is exposed to visible light, it discolors, turning from off-white to yellow to reddish ...

  9. Polybutylene adipate terephthalate - Wikipedia

    en.wikipedia.org/wiki/Polybutylene_adipate_tere...

    Infobox references. PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid. PBAT is produced by many different manufacturers and may be known by the brand names ecoflex, Wango, Ecoworld, Eastar Bio, and Origo-Bi.
