Résumé : |
Waterbornes have been experiencing technological growth for the past 20 years, but it is not a steady growth. In the last five years we have seen an unprecedented increase in new technologies available to the formulator - technologies such as improved dispersions, high performance latexes, new formulation techniques, and unique additives. These changes are the result of regulatory and environmental concerns which make it necessary for formulators to constantly keep up to date with the technology just to compete. Staying informed is worth the effort because, with current information, you can develop waterbornes with equal or better properties than conventional systems. The challenge : finding, using and personalizing the new technologies, to come up with a truly superior low VOC coating. As we have all experienced, meeting the challenge can be difficult.
Almost every coatings magazine you pick up tells you about these successful low VOC waterbornes by using comparison charts and testing results ; but they invite you to the party but forget to give you the directions. Most of the high performance low VOC coatings referred to in these articles are blends of latex and water-reducible or dispersion and water-reducible systems. So what you need to know is how to formulate so you can yield the best of both worlds. This article will overview waterbornes from a practical formulating point of view and attempt to shed some light on how to achieve specific properties in water systems. First we will deal with the odd dilemma of differentiating between the types of waterbornes, then we will look into resin choices, facets of formulation, and finally, where to expect new technologies. |
