Difficulties of Nanomaterials . . Very difficult to disperseBehave differently than traditional pigments Efficient dispersion necessary for performance benefitsNumerous nanopowder companiesSimilar chemical compositionsMany are poor quality. . . Customers become frustrated Difficult to disperseLack of performanceMost customers do not want to handle dry nanopowdersDifficult to handle and processEH
