Label free polycaprolactone triols for enhanced performance and safety

 
Polycaprolactone triols have emerged as a pivotal component in the arsenal of coating formulators, offering a multitude of enhancements to coating systems. These benefits range from improved abrasion and scratch resistance to notable scratch recovery capabilities (Jones, 2024). Polycaprolactone triols can provide an optimal balance between hardness and flexibility, thereby positioning them as a material of choice for achieving desired performance characteristics in coatings. The inherent ease of processing associated with polycaprolactone triols further solidifies their status within the industry. Their integration into coating systems not only elevates the properties of the coatings but also aligns with the processing preferences of manufacturers, making them a pragmatic option. In light of escalating environmental and regulatory concerns, it is imperative to maintain vigilance regarding the raw materials employed in polymers. The health and safety impacts of these materials are of paramount importance. Trimethylolpropane (TMP), a material traditionally utilized in a broad spectrum of industrial applications, has come under scrutiny due to potential reprotoxic effects (European Chemicals Agency). The scientific community has responded to these concerns with the development of alternative triols that circumvent the use of TMP. These novel triols are characterized by their low viscosity and absence of hazardous labelling requirements. They not only offer a safer handling experience but also demonstrate film-forming capabilities on par with traditional triols, alongside improved processing attributes. The low-viscosity nature of these alternatives contributes to a reduction in volatile organic compounds (VOCs) within coating systems, thus supporting the industry's environmental goals. Moreover, these triols provide formulators with the flexibility to customize performance characteristics, leveraging the unique properties imparted by polycaprolactone triols. This versatility is invaluable across a variety of applications, including 2K automotive refinishes, flooring, textiles, and furniture coatings. As the industry progresses, these materials are poised to play a crucial role in the development of coatings that are not only effective but also safe for both users and the environment. The data presented in this study will demonstrate the benefits of using TMP-free triols in 2K solvent borne coatings applications to achieve label free products with improved handling characteristics.
