Uni-form epoxy performs from Multi-Seals feature low outgassing properties. The highly cross-linked preshaped thermoplastics release minimal amounts of trapped gasses or condensable material under vacuum conditions and elevated heat. Low outgassing properties are key for aerospace applications, particularly in vacuum environments in which volatiles from other adhesives often condense on optics and electronics, adversely affecting their function. With a typical total mass loss of 0.35% and typical collected volatile condensable materials of 0.03% (tested per ASTM-E-595-93), these epoxies meet NASA requirements for most spacecraft materials. The resins are solid at room temperature and when heated, they melt and cure, forming a consistent seal that protects components from dust, moisture, oil, flux, solvents, conformal coatings, and other contaminants. They can be dispensed as rapidly as 200-600 parts per minute with little operator training.

Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.
