Polybutadiene Urethane Acrylates

Polybutadiene Urethane Acrylates

Polybutadiene Urethane Acrylates (PBDUA)

Designed to meet rigorous electronic applications, PBDUAs have many desirable properties typical of PBD resins, combined with radiation curability via UV/EB. Recommended for applications requiring low moisture pickup, thermal cycling resistance, and high dielectric constant.
