CryoCoat™ Thermal Insulation

CTD’s CryoCoat™ thermal insulation products are suitable for aerospace and ground-based applications. These products have excellent properties at cryogenic and elevated temperatures, can be tailored to meet a wide range of thermal and mechanical requirements, and can be applied using a variety of processing methods.

CTD’s CryoCoat™ thermal insulation systems are used to:

• Prevent formation of liquid nitrogen on the upper stages of the Boeing Delta III and Delta IV launch vehicles
• Insulate cryogenic lines at the Kennedy Space Center in regions with limited space, where foam and double wall vacuum insulated pipes would not fit
• Insulate fuel densification facilities
• Insulate NASA’s ground support systems and other industrial cryogenic equipment
• Provide low thermal conductivity components for cryogenic refrigerators and near-net shape insulation components
• Insulate liquid helium chambers in a vacuum environment, slowing the liquid helium vaporization in a loss of vacuum accident

CryoCoat™ 620T was initially developed to prevent the formation of liquid air on ground-based liquid hydrogen vent lines, and has since found numerous applications as an insulation, adhesive, sealant, protective coating, and grout for ground-based and flight applications. CryoCoat™ 620T offers excellent adhesion to many substrates with minimal surface preparation, and will cure at temperatures as low as 10°C in 8 hours. These characteristics make it especially attractive for retrofit and field installations. Known for its robustness and toughness, this syntactic foam-based insulation is resistant to UV and other environmental factors, and does not absorb moisture. It can be spray applied to large surface areas, complex surfaces, and difficult to reach areas.

CryoCoat™ UltraLight™ provides the robust mechanical properties associated with syntactic foam technology in a low-density insulation system (specific gravity from 0.08 to 0.11) with excellent thermal properties. CryoCoat™ UltraLight™ can be used as a mold-in-place insulation system on large, complex and uneven surfaces, or blown into closed molds to form near-net-shape components. CryoCoat™ UltraLight™ UL79 withstands liquid hydrogen temperatures and the elevated temperatures of re-entry from space.

The CryoCoat™ UltraLight™ consists of an adhesive layer, an insulation layer, and an outer moisture barrier/protective coating. Each component can be individually tailored to best meet the requirements of a specific application. For example, for use on a cryogenic fuel tank or rocket engine hydrogen pump, the adhesive layer will use CTD’s CryoBond™ 920 adhesive, and the outer coating will be based on CTD’s CryoBond™ XVC. The outer coating can be omitted in applications where the insulation will be exposed to a vacuum, improving the overall insulation effectiveness. The outgassing of UL-79 is low enough to maintain a stable vacuum. In applications where the insulation will be formed into a near-net-shaped part, or used on equipment requiring access for maintenance, the adhesive can be eliminated. This will allow easy removal of the insulation. CryoCoat™ UltraLight™ adheres well to itself, enabling easy insulation repair or replacement.
