| Résumé : |
In all industrial areas, there is a constant drive to improve - from regulatory pressure for favorable toxicological profiles to enhanced technical performance and improved handling - and concerning UV-/EB-curable formulations, all application fields face similar challenges. BASF is the market leader in the supply of specialty vinyl monomers and is thus intrinsically motivated to support our'UV curing' customers. Our new monomer VMOX (vinyl methyl oxazolidinone) is a reactive diluent that helps address the current challenges. Compared to traditional reactive diluents in the industry, VMOX offers a favorable toxicological profile together with technical benefits and improved formulating capabilities. This includes it being liquid at room temperature, with a very low viscosity of 4 mPa/s (at 20°C), a high reactivity with acrylates, and low colour and odour characteristics.
Overall, VMOX is particularly suited for use as a reactive diluent in UV curing coatings, inks and 3D printing applications. While providing the beneficial technical performance vinyl monomers are known for, VMOX allows innovative formulations with a favourable toxicological profile, which recently has been a challenge and is increasingly difficult to overcome with current chemistries. |
