The object of this study was to determine the effect of various levels of different adhesives on the scattering coefficients of a coating. Once the relationship of the adhesive effect on the scattering coefficient was determined an equation was to be developed to predict the optical properties of the coated sheet. This study shows that there is an increase in scattering coefficient from 5 to 10pph adhesive and after 10pph a steady decrease in the scattering coefficient as more adhesive is added. The increase is theorized to be due to flocculation of fines within the coating and the decrease due to the filling of voids in the coating. The scattering coefficient of the coating can be predicted for the adhesive addition range of 10 to 30pph by a linear equation. The data obtained in this work correlates with results of other workers using black glass and foil substrates.
