Hiding Power and Transparency

The transparency of a pigmented system denotes its ability to scatter light as Uttle as possible. The color change of a transparent pigmented system when applied to a black substrate has to be very small the lower the color change, the higher is [Pg.36]

The definition of hiding power is based on a black and white contrasting support upon which the film of coating is applied. The thickness h of the applied film is determined at the point at which the contrasting surface just disappears, as judged [Pg.30]

A modem well-equipped color measurement laboratory can use the principle of spectral evaluation described above [1.38] to simulate this procedure with a computer. The thickness of the hiding film can then be calculated in advance from the reflectance curves of a single film on a black/white substrate at a known film thickness. [Pg.31]

Transparency. Transparency is expressed quantitatively as the transparency number. This is defined as the reciprocal of the increase in color difference AE b on a black substrate obtained on increasing the film thickness h of the pigmented medium. The transparency number has the unit mm ( = L/m2). It indicates the number of liters of pigmented medium needed to coat 1 m2 of a black substrate in order to obtain a color difference of AE%b = 1 relative to this substrate. In a simplified method the transparency number can be determined by evaluating one or two points on the straight part of the AE b(h) curve. A computer method is more exact, furthermore calculations can be made using the spectral principle of spectral evaluation (see above). For standards, see Table 1 ( Transparency ). [Pg.32]

Finishing not only improves the application properties of a pigment, such as hue, tinctorial strength, brilliance, transparency/hiding power, dispersibility, and flow behavior, but also considerably enhances its lightfastness and weatherfastness and its solvent and migration resistance. [Pg.203]

Disazopyrazolone pigments, for instance, can be tailor-made for various applications in order to provide features such as high transparency or good hiding power, easy dispersibility, and high tinctorial strength. [Pg.265]

P.O.36 is a reddish, somewhat dull orange pigment which provides very good lightfastness and weatherfastness. It is a highly important pigment. The commercially available types differ considerably in their hiding power/transparency. Different types vary even in terms of shade - the opaque version is redder and noticeably cleaner - and other properties, as well as fastness properties. [Pg.359]

OPACITY. The optical density of material, usually a pigment the opposite of transparency. A colorant or paint of high opacity is said to have a good hiding power or covering power, by which is meant its ability to conceal another tint or shade over which it is applied. See also Paints and Coatings. [Pg.1152]

Significant pigment attributes are tinctorial strength, durability (photochemical stability), hiding power, transparency, and heat and solvent resistance. Other properties include brightness (saturation), gloss, rheol-ogy, crystal stability, bleed resistance, flocculation resistance, and other properties associated with specialized applications. [Pg.1308]
