Abstract:
Objective:To evaluate the effects of pigment concentration on spectral reflectance of pigmented silicone elastomer.Methods: Six kinds of pigment at different concentrations was respectively added into MDX-4-4210 silicone elastomer to prepare six series of single-chroma-samples, including red, yellow, blue, brown, white and black.The pigment concentrations to base elastomer were set at 0.1, 0.2 , 0.3, 0.4, 0.5, 0.6,0.7, 0.8, 0.9 and 1.0C, respectively while other conditions were kept the same. C is the maximum pigment concentration in practical use. The target samples were also prepared. By spectrophotometer, the spectral data of the single-chroma-samples and target samples were measured.Results:With the increase of pigment concentration, the spectral reflectance of the six series of single-chroma-samples and target samples decreased.Conclusion:Increase of pigment concentration may result in decrease of spectral reflectance of single-chroma-samples and taget samples.
