HM-2520 is a neutral-cure, low-VOC sealant that enables parts to be moved immediately upon application. Has a tensile strength of 700 psi and service temperatures ranging from -50° to 300°F (-45° to 150°C). Is formulated for automated assembly. Is said to combine the immediate green strength of a hot melt adhesive with the long-term performance of a reactive silicone sealant and improved resistance to movement during cure and at high temperatures under load.

The 2800 Series LLHP ultra-low frequency Vibration-Isolation Workstation is for lighter loads. Is designed to meet vibration-isolation requirements of sensitive equipment weighing around 100 lb. (200 lb. max). Uses trifilar pendulum mounts and active-air suspension; has a high level of vertical axis isolation. Tabletop is 30" sq., 2" thick and can be constructed of lightweight aluminum extruded core or a variety of composite cores. Surfaces available with or without mounting holes. Incorporates automatic leveling and low natural frequencies (1.1 Hz along horizontal axis and 1.4 Hz along vertical axis). Reportedly can achieve vertical isolation efficiency of 96% and horizontal isolation efficiency of 97% (at 10 Hz and above).

SN100C(510) Pb-free flux cored solder wire is said to generate little spatter, even with the high solder tip temperatures required to burn off polyurethane insulating enamel. Reduces risk of copper erosion during soldering and slow growth of the interfacial intermetallic layer in service. Other features include minimal cracking of flux residue, low fuming and odor, and high-temperature soldering. Can be used with soldering tip temperature up to 480°C.
