| Résumé : |
Dimerized fatty acids have long been used in polyamide hot-melt adhesives. It can be expected that some of the benefits they add to these adhesives, like flexibility and hydrophobicity, can be transferred to other adhesive resins.
Polyurethanes, where the dimerized acid is easily introduced via a polyester polyol, is an obvious candidate. Uniqema has developed a range of derivatives of dimerized fatty acids under the product name of Priplast. These dimerized acid-based polyester polyols were studied as building blocks for reactive hot-melt adhesives. Initially, the influence of dimerized fatty acid-based polyester polyols on the properties of polyurethane elastomers was tested.
Subsequently, the properties of reactive polyurethane hot-melt adhesives were studied after full cure (final adhesive properties). Thirdly, a study was performed on the initial bond of the adhesives (green strength) and ways to improve the green strength. The results of the study are presented here. |
