| Résumé : |
Direct-to-Metal (DTM) applications require reactive materials having the correct balance of physical properties including both flexibility and toughness. These features are necessary to ensure that the finished part will withstand the rigors of forming and process handling with scuffing and surface abrasion. Also the final coating must adhere to a wide variety of metal types that may have surface contamination that make adhesion a challenge.
This work will investigate and report the performance results of acrylated monomers and oligomers when subjected to typical end-use tests designed to measure the flexibility and adhesion characteristics of coatings. Oligomers having adhesion promoting characteristics will be tested alone or in combination with monomeric acid functional adhesion promoters to determine thebest type of oligomer to use for a given substrate.
Also the correct level of addition of the adhesion promoters will be determined to obtain optimum performance results. In addition moisture resistance will be explored as it relates to oligomer type.
Another significant development in the can manufacturing industry has involved the elimination of Bisphenol A (BPA) from coatings that are intended for food packaging applications. The performance benefits of polyester acrylate oligomers will be highlighted compared and contrasted to those of Bis A epoxy acrylate oligomer. Each of the formulations used in this study are in fact BPA free. |
