ThreeBond 2045B/2145B
Room-temperature curing-type heat dissipation epoxy resin suitable for lithium ion batteries
05/05/2025
In the evolving landscape of electronics and electric vehicles (EVs), efficient thermal management and robust bonding solutions are paramount. ThreeBond addresses these needs with its innovative epoxy resin systems : ThreeBond 2045B and 2145B.
ThreeBond 2045B and 2145B constitute a two-component, room-temperature-curing epoxy resin system. Designed for applications requiring superior heat dissipation and strong adhesion, this system is particularly suited for :
- Electric and hybrid vehicle battery modules
- Lithium-ion batteries in smartphones and tablets
- Bonding and sealing around heat-generating components
The system comprises:
- ThreeBond 2045B: Epoxy resin (pink)
- ThreeBond 2145B: Polyamine hardener (light blue)
Upon mixing, the components cure at room temperature, forming a durable bond with excellent thermal conductivity
Features
- The cured resin exhibits high thermal conductivity, effectively dissipating heat from electronic components and batteries, thereby enhancing performance and longevity.
- This epoxy system provides robust adhesion, eliminating the need for mechanical fasteners in many applications, which simplifies assembly and reduces weight.
- Meeting the UL94 V-0 flammability standard, the resin enhances safety by resisting ignition and inhibiting flame propagation.
- The ability to cure at ambient temperatures reduces energy consumption and simplifies processing, aligning with environmental sustainability goals.
- Ideal for use on EV battery modules, consumer electronics or industrial equipment.
