Time Domain NMR for rapid assessment of adhesive and coating molecular mobility
This solution utilizes Time Domain NMR (TD-NMR) to evaluate molecular mobility in adhesives and coatings, linking these metrics to performance. It offers insights into molecular dynamics during adhesive setting, enhancing formulation and application processes.
Overview
Time Domain NMR (TD-NMR) offers a novel approach for rapidly assessing the molecular mobility of components within adhesives and coatings. This solution bridges the gap between molecular dynamics and performance, providing real-time insights into the setting processes of coatings and the fibril formation in pressure-sensitive adhesives. The ability to measure and analyze molecular motion through TD-NMR can significantly enhance the understanding and development of high-performance adhesive products.
Technical specifications
Key features:
- Utilizes TD-NMR to quantify molecular mobility, providing insights into cross-link formation and solvent evaporation in coatings.
- Analyzes molecular dynamics in pressure-sensitive adhesives to assess fibril formation.
- Employs Multiple Quantum methods for detailed evaluation of entangled and crosslinked systems.
- Initial validation involves measuring NMR relaxometric parameters such as T1, T2, and multiple quantum coherence.
- Use of microparticle reference samples accelerates data collection by maximizing surface/volume ratio.
Technology readiness level
The technology is currently at Technology Readiness Level 4. Initial validation has been conducted, with ongoing efforts to refine data collection and analysis methods to suit various adhesive and coating formulations.
