AI Technical Summary
Current two-component polyurethane thermally conductive adhesives suffer from poor adhesion to untreated aluminum, toxicity due to isocyanate components, and inadequate latency characteristics, which affect their practicality in thermal management applications.
A two-component thermally conductive adhesive formulation is developed, featuring isocyanate components with at least two different aliphatic prepolymers of higher functionalities and low monomeric diisocyanate content, along with a water scavenger in the isocyanate component to enhance shelf-life and latency.
The formulation achieves improved thermal conductivity greater than 1.5 W/mK, enhanced adhesion to aluminum, reduced toxicity, and extended latency, making it suitable for efficient thermal management in applications like electric vehicle battery cooling systems.
