Designed for use in the
aerospace and defence sectors, this combines low outgassing, dielectric stability and on- demand UV curing to address the reliability and production throughput requirements in these industries.
Dymax 9773 is very low outgassing, passes ASTM E595 with low Total Mass Loss, and is NASA MAPTIS listed. It also satisfies MIL-STD-883 Method 5011, which shows that it remains electrically insulating, dielectrically stable, and physically intact after prolonged high- temperature exposure. The threat of ionic migration is a critical reliability risk for electronics in remote environments, so the adhesives used must show stable electrical performance. In addition to demanding extreme reliability, defence manufacturers now also need to produce
more, faster and at scale. Meeting the demands, Dymax 9773 is a single part, non-slumping, adhesive which cures in seconds with UV/visible light. This represents an important upgrade on slow, multi-part epoxies or silicones. It is also compatible with automated dispensing and jetting within scalable production settings. No solvents or halogens are used in Dymax 9773, and it is Restriction of Hazardous
Substances (RoHS) compliant, helping manufacturers to meet Defence Environmental Protection (DEPR), Environmental Protection Agency (EPA), and any other environmental regulations that apply. “This adhesive was designed to fulfil a range of purposes in mission-critical aerospace,
defence and optics applications,” said Matt Baseley, head of sales at Intertronics. “This includes shock and vibration absorption, encapsulation, ruggedisation and reinforcement of electronic components, and underfill.”
Despite being designed for easy installation, these aluminium components are said to
feature an incredibly high pull out force to permanently retain two plastic components to each other. The pin has raised barbs that are angled opposite to the direction of insertion, which allows the pin to provide a secure, tamper resistant, assembly. For industries with heightened requirements, these pins can also be manufactured from austenitic stainless steel. According to the company, the Press-N-Lok Pin’s permanent seating makes it ideal for
plastic medical housings such as the handles for arthroscopic surgical instruments and diagnostic equipment enclosures. SPIROL also offers complementary Application Engineering support in tandem with a
comprehensive line of Solid Pins and other engineered fastening options. Its Application Engineering Team will review your application details and assembly requirements and assist in not only selecting the most appropriate engineered fastener, but also in recommending the appropriate hole size, tolerances, and installation method. If installation equipment is
required, SPIROL offers a standard line of Pin Installation Technology, ranging from manual to fully automatic models, that can be customised to suit requirements.
20 With satellite components exposed to extreme
temperature swings, ranging from -100˚C to +120˚C every 90 minutes, a cycle that repeats roughly 16 times per day, maintaining thermal stability is vital to ensuring a spacecraft’s reliability and lifespan. Leveraging the open-cell structure of AeroZero Tapes, engineers can create a thermal barrier that limits temperature differentials, helping to create smoother, more predictable component performance. The AZ-Tapes also function as a structured
vacuum gap that significantly limits conductive heat transfer and insulates sensitive electronics and batteries. Even those positioned near heat-intensive solar array and between sensitive components are protected – providing robust thermal protection for the cyclical thermal events experienced by spacecraft in LEO. This next- generation thermal stability sets the foundation for more efficient, reliable satellite systems. “Our AeroZero Tapes are helping to deliver a
new standard of passive thermal management for LEO satellites,” commented Tim Burbey, president of Blueshift. “Our customers are using our tapes because satellite designs are evolving to fit smaller, more compact footprints, and thus require materials that survive the extreme temperature swings of space without adding the bulk or weight that typify traditional TPS. By leveraging a structured vacuum gap and open- cell architecture, our AZ-Tapes empower engineers to extend the lifespan of their satellites.”
The testing concluded that the tapes provide 19x
lower thermal conductivity (0.008 w/mK) and 6x lower thermal diffusivity when compared to traditional polyimide tapes, marking a significant advancement in satellite thermal protection.
