JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Bonding technologies are now widely used in all types of industries. Adhesive innovation is focusing not only on improving mechanical properties, but also on integrating additional functions like flame retardancy.

CIn 2009, Huntsman Advanced Materials used its extensive knowledge in formulating self-extinguishing materials to develop and launch its Araldite 2033.
The properties of this two-component structural epoxy adhesive include flame retardancy, low smoke density and low toxic emissions, and are in compliance with the requirements for the UL94 V-0 flammability classification.
Due to its combination of good mechanical performance and self-extinguishing properties, Araldite 2033 was selected as the adhesive used to bond and stabilize the components in power packs for marine applications.
During the manufacturing process, the electronic components are assembled on a printed board. The adhesive bonds the components to the board and also acts as a damping material to prevent soldering material fatigue. The assembly needs to resist vibration and temperatures ranging from -10°C up to 100°C.
For these marine applications, the adhesive needs to combine high toughness, good temperature resistance and excellent durability.
