What do you have to clean the surface with (before application and after removal)?

The surface shall be wiped with a clean, solvent (isopropyl alcohol or other approved cleaning solvent) dampened cloth, followed immediately by wiping with a clean dry cloth. Residue of previously applied adhesives, sealants, or fillet sealing materials shall also be removed. An appropriate chemical conversion coating may be applied to the aircraft skin surface and allowed to dry per manufacturer's instructions.

What is the service temperature of your products?

-65°C to 135°C (-85°F to 275°F)

How long of a lead time for shipments?

Typically two weeks, ARO.

What is the gel?

The gel is a pre-cured polyurethane formulation that is formulated to retain the soft and tacky physical properties throughout the service temperature of the product.

What is the shelf-life?

The shelf life for pre-cured products (tape and gaskets) is indefinite when stored in the original packaging and protected from UV exposure. The shelf life of injectable sealants is 6 months from the date of manufacture.

Are the gaskets fully cured when we get them?

Yes, the polyurethane sealant is mixed and cured at our facility.

How do we dispose of injectables and the two part containers they come in?

Any unused material should be mixed by dispensing through a mixing straw or injected into a small container and stirred by hand. Once the material has been mixed it may be disposed of in regular trash containers along with the cartridges.

Can the antenna gaskets be re-used?

Av-DEC recommends that if the antenna is removed the gasket be replaced to ensure the best environmental protection and electrical bonding performance. We realize that some circumstances will requires reuse of a gasket. Remove the antenna carefully to prevent bending the aluminum mesh. Install the new antenna and Av-DEC recommends replacing the gasket as soon as practical to ensure the best environmental protection and electrical bonding performance is maintained.

Can the SLG be made in smaller quantities?

Injectable sealants are packaged in 50cc and 200cc cartridges. An extra mixing straw is included in all packages to allow the user to continue use if the sealant is allowed to gel in the mixing straw. The material must be used within 24 hours of opening the package.

Can the shelf life be extended?

Av-DEC does not recommend extending the shelf life of injectable products.

If the gaskets are exposed to UV and the color changes is the gasket still usable?

It depends... IF stored properly, this should not be an issue.

Do you have a mil Spec or do you qualify under a QPL?

There are currently no Mil Specs that define our materials.

Do you have any distributors foreign or domestic?

We currently do not have distributors. However, we do have representation in Asia, Europe and South America.

Can Av-DEC make gaskets from existing drawings?

Yes, if Av-DEC material is required for the application.

Are any of the products hazardous?

All of our products are considered non-hazardous and can be shipped via air.

Can customers buy factory direct?

Yes, customers can buy factory direct. We accept Visa, MasterCard and American Express.

Conductive Antenna Gaskets

Av-DEC's® pre-cured polyurethane antenna gasket has an aluminum carrier die cut to fit the antenna. It is also designed for use as an environmental sealant. The flexible nature of this system provides for easy access for inspection or repair long after the original application. The system demonstrates excellent cohesion after installation, and provides a high degree of environmental protection, while still allowing for easy removal and antenna bonding. Currently, Av-DEC® produces over 1000 different antenna gasket footprints.
