HI-TAK^® Antenna Gaskets

Pre-cured, Low-resistance, Polyurethane Antenna Gaskets That Deliver Improved Avionics Reliability.

An Applicable Sealant for Sensors and Probes.

Av-DEC HI-TAK conductive antenna gasket system is designed to satisfy environmental sealing requirements in the aviation industry. The gaskets are constructed to meet Federal Aviation Administration (FAA) airworthiness standards. They are recommended for protecting, maintaining, and repairing defective aerospace structures and assemblies. An Aesthetic Technical Build for Standard Sealing Applications

HI-TAK conductive antenna gaskets are constructed with polyurethane-encapsulated aluminum mesh carriers that are integrated to achieve excellent bonding. The gaskets are ideal for:

• Preventing corrosion from direct electrical and electrochemical corrosive agents.
• Compatibility with metallic and painted surfaces - which ensures optimal bonding when applied on antenna components
• Ease of removal after installation, simplifying periodic repairs and maintenance tasks

Pre-cured and Die Cut for Maximum Protection

Av-DEC HI-TAK polyurethane conductive antenna gaskets are pre-cured to guarantee effective application. They are also die cut to match the antenna application, which offers maximum surface protection when applied. The pre-cured polyurethane build ensures the sealant is maintained during vibration and thermal fluctuations. Excellent material memory and elasticity ensure a proper seal. Benefits include:

• Creating an extensive pressure seal that protects surfaces when extensive vibrations occur
• Providing maximum protection as an environmental seal thereby protecting surfaces from moisture
• Eliminating the use of polysulfides or other sealing agents and keeping the application surface clean and free of residues
• Excellent and even bonding which protects the entire surface. Increases the life span of antennas and decreases the costs associated with structural repairs or replacement
• Reducing the return-to-service time and speeding up maintenance durations due to quick installation and removal procedures

Increased Resistance to Corrosive Agents

The gasket properties are ideal for protecting surfaces from moisture and fluids. This includes oils, hydrocarbons and chemical substances which could harm the antennas and sensors in the airplane. The HI-TAK polyurethane conductive antenna gasket has an impressive resistance profile. The benefits relating to its resistance profile include:

• Providing complete protection even under excessive vibrations
• Protecting sealed components from the effects of moisture and humidity
• Leaving behind no silicon oil residues during application or removal
• Non-hazardous, environment friendly sealing

A Versatile Environmental Seal for Original Equipment Manufacturers (OEMs)

Due to the innovative blend of polyurethane and aluminum, the HI-TAK polyurethane conductive antenna gasket system is great for diverse industrial applications. Users can also apply it to the following components to prevent corrosion:

• Lights
• Sensors
• Probes
• Hardware Assemblies
