Av-DEC Hi-TAK StructureSeal® is a pre-cured polyurethane sealant with a crush-resistant nonconductive carrier.  The polyurethane sealant demonstrates an exceptional balance between cohesion and adhesion which allows it to provide a consistent seal while remaining easy to remove.  The innovative carrier provides a rigid mechanical stop to increase crush resistance.  Hi-TAK StructureSeal is available in both two-sided sticky roll form and die cut gasket form.  It can be supplied with optional PTFE backing to provide a single-sided sticky alternative.  All four configurations are available in a flame retardant (FR) formulation.  Recommended uses: under floor boards, lavatories, galleys, door sills and on top of stringers.

Av-DEC’s Hi-TAK Fuel Access Panel Gasket, with its “peel and stick” application method and its polyurethane sealant, offers many advantages over commonly-used grease-impregnated gaskets:  ease of use resulting in reduced installation time; no VOCs that evaporate over time and lead to voids that trap moisture which promotes corrosion; infinite shelf life when stored in original packaging and protected from UV exposure;  no use of grease, no need to degrease and reapply grease every five years, no greasy mess.  

The gasket’s aluminum mesh provides a conductive path for lightning strike protection over the life of the gasket and reduces fretting to the wing skin and door surfaces.  Its fuel-resistant polyurethane sealant fills voids and surface imperfections to protect the faying surfaces from moisture intrusion and corrosion, providing a long-term environmental seal.  The  flexible and cohesive nature of the gasket provides a high degree of environmental protection to help reduce or eliminate corrosion, reducing the scrap rate of tank access doors, decreasing cost and saving time, and improving the reliability of the air vehicle.

Sprayseal

 

Av-DEC SpraySeal® for aircraft interiors is a two-component urethane material that is designed to create a watertight, flexible sealant to protect aircraft surfaces against corrosion. The low viscosity allows the material to be applied via spray or brush application. Av-DEC SpraySeal's transparent nature allows for inspection of the protected surface through the material without removing the sealant from the surface. The adhesive strength and cohesive strength for this material are carefully balanced to create a durable coating that can be cleanly removed for service or access to coated parts. This product is commonly used to protect large contiguous areas as well as irregular or complex structural surfaces, particularly corrosion-vulnerable areas such as under lavatories and galleys.

QuadABC

 

The Av-DEC® Hi-TAK Quad Seal™ is Av-DEC's recommendation for the best way to achieve a complete and total seal between an aircraft antenna and the surface of the aircraft when a fillet seal is required. This process is achieved when four different Av-DEC® products are combined in conjunction with each other. The Hi-TAK® Polyurethane Conductive Gasket makes a seal between the antenna and aircraft interface, StretchSeal® is used to wrap the coaxial connector for sealing, Self-Leveling Green® is placed at the connector to antenna interface to provide ample sealant, and Thixoflex Black® is used around the antenna for a fillet seal.
