  2. Paint sheen - Wikipedia

    en.wikipedia.org/wiki/Paint_sheen

    The sheen [4] or gloss level of a paint is principally determined by the ratio of resinous, adhesive binder, which solidifies after drying, and solid, powdery pigment.The more binder the coating contains, the more regular reflection will be made from its smooth surface; conversely, with less binder, grains of pigment become exposed to the surface, scattering the light and providing matte ...

  3. Powder coating - Wikipedia

    en.wikipedia.org/wiki/Powder_coating

    Example of powder coating spray guns. The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a negative charge to the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the ...

  4. Acrylic paint - Wikipedia

    en.wikipedia.org/wiki/Acrylic_paint

    Acrylic paints with gloss or matte finishes are common, although a satin (semi-matte) sheen is most common. Some brands exhibit a range of finishes (e.g. heavy-body paints from Golden, Liquitex, Winsor & Newton and Daler-Rowney); Politec acrylics are fully matte. [22] As with oils, pigment amounts and particle size or shape can affect the paint ...

  5. Electrostatic coating - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_coating

    Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.

  7. Paint - Wikipedia

    en.wikipedia.org/wiki/Paint

    The paint type known as Emulsion in the UK and Latex in the United States is a water-borne dispersion of sub-micrometer polymer particles. These terms in their respective countries cover all paints that use synthetic polymers such as acrylic, vinyl acrylic ( PVA ), styrene acrylic, etc. as binders. [ 22 ]

  8. Superhydrophobic coating - Wikipedia

    en.wikipedia.org/wiki/Superhydrophobic_coating

    In industry, super-hydrophobic coatings are used in ultra-dry surface applications. The coating can be sprayed onto objects to make them waterproof. The spray is anti-corrosive and anti-icing; has cleaning capabilities; and can be used to protect circuits and grids. Superhydrophobic coatings have important applications in maritime industry ...

  9. Salt spray test - Wikipedia

    en.wikipedia.org/wiki/Salt_spray_test

    The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
