Effect of Aluminum Flake Orientation on Coating Appearance

January 1, 2001
Author(s)
L Sung, Maria Nadal, M E. McKnight, Egon Marx, R Dutruc, B Laurenti
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using

New Primary Standard for Specular Gloss Measurements

December 1, 2000
Author(s)
Maria E. Nadal, E A. Thompson
The measurement of specular gloss consists in comparing the luminous reflectance from a specimen to that from a calibrated gloss standard, under the same geometric conditions. The standard recommendations for the gloss standard are discussed. A new primary

Standardization of Reflectance Colorimetry for Manufactured Products

October 1, 2000
Author(s)
Maria E. Nadal, E A. Early
The National Institute of Standards and Technology is conducting a study to advance the science of characterizing and modeling the appearance characteristics of coatings. This paper briefly describes two projects in the area of reflectance colorimetry

Characterization of Coating Microstructure Using Laser Scanning Confocal Microscopy

August 1, 2000
Author(s)
Li Piin Sung, Maria E. Nadal, Paul E. Stutzman, M E. McKnight
The appearance of coating materials depends on the physical attributes of the object's interaction with light. These physical attributes include the light source, the angle of illumination, the viewing angle, and the optical reflectance properties of the
