OB-100-1/4 is an OMEGABOND® 100 fast (8 to 12-minute setting time), room temperature, two-part epoxy. Recommended for easy temporary and permanent bonding of beaded wire and "cement-on" thermocouples. Adheres to metals, ceramics, epoxy laminates, glass, wood, concrete and many other materials-for temperature measurements up to 129°C (265°F). It is not recommended for those endeavoring to achieve the ultimate in precision and speed of response, since this unfilled system has a relatively low thermal conductivity.
