Résumé : |
Over the last twenty years the surface coatings industry has undergone dramatic shifts in the direction of formulation work. Demands for increasing performance have certainly always been present, but in the last two decades consideration for the environment and worker safety have become even more important than cost effectiveness. Much of the safety improvements that have been implemented have occured as a direct result of legislation imposed upon the industry.
Historically anti-corrosive coatings relied upon resins which required large quantities of volatile organic solvent and lead or hexavalent chromium pigments. These are no longer acceptable in today's environmentally conscious world. The move towards water-based coatings and away from toxic pigments is already well underway, but the need for improvements is (and always will be) there. Current pigments have approached the performance of lead and chrome pigments, but, as yet, have not surpassed them. In addition, these materials are more complicated to work with than their toxic forbearers.
Meticulous formulation is required to optimize performance of non-toxic corrosion inhibitors. The proper loading level and pigment volume concentration must be obtained. The old adage 'more is better' does not apply to these new pigments. While the research is still underway to find the perfect replacement for leads and chromes, formulators today need techniques which will help them now. It has been found that several of today's non-toxic corrosion inhibitors can work synergistically with each other to give a performance greater than either one alone. |
