Résumé : |
During the 50 years since the development of organoclay Theological additives, organoclay manufacturers, the coatings industry, and other consumers of organoclays have found that measuring the theological properties of solvent pregels does not provide an accurate assessment of the performance of formulated products. Different lots of the same type or similar grades from various producers have been subjected to various pregel viscosity measurements as incoming raw material performance tests. Organoclay pregels have also been used to assess the efficiency of an organoclay, to provide a basis for comparison with other guides, and to determine finality differences between manufacturers. It is the objective of this article to provide practical information regarding the problems encountered by the organoclay user when attempting to measure quality by testing pregel viscosity. Using some common test criteria use also explain why the better indicator of true organoclay quality is performance of a complete paint formulation (or other product reflecting the intended final application/product evaluation). |
