Electronics produce a lot of heat, and the smaller they are, the more heat they produce.
Appli-Tec’s high-performance, thermally conductive adhesives and epoxies serve two purposes:
Used in industries where performance is critical, including aerospace, defense, sensors, and devices, Appli-Tec’s adhesives are ready to use for:
All Appli-Tec adhesives come pre-tested, pre-mixed and pre-packaged in sizes ranging from 1cc – 30cc for hand dispense syringes to 3cc – 55cc for pneumatic dispensing.
The materials listed can be modified to suit your application — e.g. adding spacer beads, changing color, more or less thixotropy, and altering cure rates.
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.
Designed specifically for potting circuit board connectors. With its 4-hour pot life, the material is ideal for automated dispensing and features controlled flow – making it easy to deposit. 5302 meets NASA’s outgassing requirements and has a wide range of curing options. The material bonds well with most substrates.
Key Features: Cured material can withstand high temperature environments and is resistant to fuel, lubricants, water, and weather. A pre-mixed, degassed, tested and frozen epoxy.
An electrically isolating material, 5308 was designed specifically for underfilling, staking and encapsulating electronics on circuit boards, as well as potting and encapsulating power supplies, transformers, and coils. Featuring a 3-hour pot life, 5308 has good flowability, making it ideal for applications requiring a self-leveling material. The material meets NASA’s outgassing requirements, is resistant to solvents and chemicals, and is considered non-hazardous per D.O.T. regulations.
Key features: High Tg, low shrinkage, flowable, 3 hour pot life. A pre-mixed, degassed, tested and frozen epoxy.
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 re-mixed, degassed, tested and frozen polyurethane adhesive paste.
Because they 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 electronic 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. A dark gray, pre-mixed, degassed, tested and frozen polyurethane adhesive.
Featuring an excellent dielectric strength of 700 volts/mil, 5315 is ideal for applications involving sensitive electronics that don’t require a high thermally conductive epoxy. The material, which is self-leveling and high adhesion, is specifically designed as a casting compound to encapsulate power supplies, transformers, and coils. 5315 has a long work life, low shrinkage, and excellent electrical insulating properties, as well as being resistant to solvents and chemicals. This adhesive has a high Glass Transition Temperature of 100oC.
Key features: Environmentally friendly, D.O.T. non-hazardous. A black, pre-mixed, degassed, tested and frozen epoxy.
