Appli-Thane® Aerospace Adhesives

Our lowest viscosity Appli-Thane product, 7125 is ideal for potting and encapsulation of advanced electronic assemblies. With a Shore A hardness of 70, the soft material provides resistance to vibration, as well as low shrinkage, for minimal stress on components during cure.

The material passes NASA’s outgassing requirements and provides strain relief for many bonding applications where high thermal conductivity isn’t required.

Key Features: Low viscosity, self-leveling, D.O.T. non-hazardous, transparent, and flexible. De-airs easily. Pre-mixed, degassed, tested, and frozen polyurethane adhesive.

Ideal for aerospace applications as it meets NASA’s outgassing requirements. The cured material’s ability to not crack or harm bonded rigid components during thermal cycling is a major plus. Appli-Thane 7300 is also used in manufacturing and automated dispensing applications due to its 4-hour pot life. Provides best-in-class thermal conductivity for applications requiring aggressive heat dissipation of components.

Key features: Self-leveling, injectable; cures to a semi-flexible material with relatively low modulus and very low Tg. Pre-mixed, degassed, tested and frozen polyurethane adhesive.

The perfect choice for automated dispensing. A self-leveling injectable compound, Appli-Thane 7308 maintains its dispensability for over 8 hours. The material can be cured during mass-reflow without disturbing the placement of components, thus eliminating several costly “component level” processing steps. It also eliminates the need for a separate cure cycle. The material meets NASA’s outgassing requirements and cures to a semi-flexible material with low modulus and a very low Tg.

Key features: Electrically insulative, semi-flexible, will not crack or harm bonded rigid components during thermocycling. A red pre-mixed, degassed, tested and frozen polyurethane adhesive paste.

Because epoxies are hard and high modulus after cure, many aerospace epoxy systems will fail when exposed to extreme thermal cycling and vibration environments. Designed as replacement material for these systems, Appli-Thane 7340 is an easy-to-use polyurethane. It won’t harm, bend or break highly fragile substrates, such as glass and ceramic, when exposed to vibration and extreme thermal cycling. A thixotropic, thermally conductive compound, Appli-Thane 7340 passes NASA’s outgassing requirements and is suitable for electro-optics bonding and staking and may be used as a fillet as well.

Key features: Thixotropic, electrically insulative; cures to a tough and flexible material with low modulus and very low Tg. Ideal for electro-optics applications. A dark gray, pre-mixed, degassed, tested and frozen polyurethane adhesive.

This thixotropic, easily reworkable aerospace urethane is ideal for bonding and staking applications. The material features a room temperature cure while also meeting NASA’s low outgassing requirements. With low modulus and low Tg, Appli-Thane 7800 is a suitable substitute for many silicones in electronic applications. Choose from translucent or a blue color if visual inspection is needed.

Key features: Thixotropic, electrically insulative, flexible; features long pot life, short cure time and a long shelf life. A pre-mixed, degassed, tested and frozen polyurethane adhesive.

The free-flowing version of our 7800 material, Appli-Thane 7810 is ideal for coating applications. Both 7810 and 7800 are often used together for “dam and fill”: use the higher viscosity 7800 to create the dam, then 7810 to fill in. Appli-Thane 7810 features good flow and wetting, is easily reworkable, and meets NASA’s low outgassing requirements.

Key features: Free flowing, electrically insulative, and low outgassing. A room temperature cure and long pot life. A pre-mixed, degassed, tested and frozen polyurethane adhesive.
