Some Vistamatt grades undergo post-treatment with organic or inorganic surface modifiers to enhance dispersion, matting efficiency, or compatibility with specific resin systems. These treatments are applied at low levels (≤5% by weight typically). If you require confirmation of TSCA status for a specific treated grade, please contact us with the grade number and we will provide the full ingredient disclosure for your regulatory review.
