DuPont launches BETASEAL™ 900EI, an electrically-isolating battery pack sealing and bonding adhesive. The adhesive enables efficient battery assembly and field serviceability.
PU-based Adhesive & Sealant
With BETASEAL™ 900EI, EV battery packs and panels can be assembled and serviced without compromising sealing performance. The adhesive, bonds coated metals, pretreated thermoplastics, and composites – or any multi-material combination. It is a one-component moisture-curing non-conductive
polyurethane-based adhesive and sealant.
Currently in production and prototyping with multiple global automotive manufacturers, BETASEAL™ 900EI benefits include:
-
Reliable environmental sealing and durable bonding
-
Reduction or elimination of mechanical fasteners
-
Electrical insulation for sensitive battery components
-
Room temperature curing – withstands 0.5 psi leak testing after five minutes
-
Meets debris and water ingress performance per IP67 & IP6K9K
-
Resistant to high pressure and high-temperature spray (car wash simulation)
-
Optimized hardness to enable efficient field serviceability and pack recyclability
-
Acts as a secondary barrier if battery modules leak
-
Elimination of manual gasket application
