CEMEDINE UT100B Urethane Elastic Adhesive is a one-component, room-temperature curing elastic adhesive developed for bonding and sealing electrical and electronic components. It provides excellent adhesion to engineering plastics, synthetic rubber and metals while maintaining a flexible and durable cured bond.

UT100B uses a reactive special-polymer system that combines high strength with high elongation. After curing, the adhesive can absorb vibration, impact and dimensional movement between different materials, making it particularly suitable for electronic devices and assemblies that require long-term bonding reliability.
