Application
- Preparation and properties of toluene-diisocyanate-trimer-modified epoxy resin: Discusses the enhancement of epoxy resin properties through the self-polymerization of TDI, aiming to improve performance in industrial applications (X Zhang, L Qiao, X Lu, L Jiang, T Cao, 2019).
- A simple method for the quantification of free isocyanates on the surface of cellulose nanocrystals: This research focuses on the carbamation of cellulose using TDI, which is critical for the modification and enhancement of nanocellulose surfaces for various applications (H Abushammala, 2019).
- Fluorescent linear polyurea based on toluene diisocyanate: Reports the preparation of a TDI-based polyurea that exhibits broad emission spectra, suggesting potential uses in sensor applications and material science (H Cao, B Li, X Jiang, X Zhu, XZ Kong, 2020).
