Résumé : |
Wax coated silica matting agents are widely used in the coatings industry to reduce gloss and to enhance such film properties as scratch resistance, feel and flexibility. Further benefits arise when wax coated silicas are produced by co-milling the wax with the silica at temperature in a fluid energy mill. Incorporation of the wax in this manner improves the compatibility of the wax coated silica with other components of the lacquer formulation and influences the initial settling characteristics on the lacquer as well as preventing hard settlements on storage.
The paper reviews recent work within the Crossfield Group Research Laboratory in which the effect of co-milling various waxes with silica on such lacquer properties as initial dispersion, settling rates and redispersion characteristics, has been investigated and compared with the properties of the uncoated product. |
