- The Halthane series of urethane adhesives synthesized by Lawrence Livermore Laboratory (1) are being studied for application to Pantex assembly processes. The series consists of three each two-part systems designated 73-14, 73-18, and 87-1. The 73-18 system to be used was chosen as the first of the three for physical property testing. Each system has certain advantages, and is designed for a specific application. Systems 73-14 and 73-18 have a lower viscosity than 87-1. System 73-18 has a lower tensile and compressive modulus than 73-14 and 87-1. The increasing order of pot life would rank 73-18, 87-1, and 73-14. All three systems reach two-third hardness in 16 hours. These new adhesives will be investigated and utilized by several production plants in the ERDA complex. The Pantex study effort will include measurement of bulk viscosity, cure time, butt tensile strength, lap shear strength, hardness and compatibility. One significant part of the study is familiarization with process and handling requirements that may be unique with the Halthane series.
