New conductive expoxy resin ready to launch to the market

Graphene has truly amazing properties – it’s 200 times stronger than steel, conducts better than silver, can be levitated by magnetism, is nearly transparent, can self-repair holes and tears, and has a staggering area to mass ratio (2630 m2/g). The material already has commercial applications in touch screens, solar panels, batteries and capacitors. Tennis brand, Head, has even launched a range of graphene tennis rackets.

To illustrate its strength, one square metre of graphene used as a hammock will support a fat 4 kg cat, whilst weighing only as much as one of the cat’s whiskers.

New graphene based adhesive

Scaling up production and finding practical ways of deploying it are challenges that continue to be attacked in labs and factories around the world. One new product, released in February 2017, that exploits graphene’s amazing conductive properties and its great strength is a new metal bonding adhesive range called collectively G6-EPOXY – one example being G6E-P-60.

The new adhesive cures at room temperature (although the optimum is to cure overnight at 25°C followed by 4 hours at 80°C) and has excellent temperature stability once set. After mixing, G6E-P-60 becomes an easily applied thick paste and will bond a wide range of substrates including metals, glass, composites and ceramics.

A metal bonding adhesive with excellent electrical conductivity is, of course, perfect for use with electronics and can have more flexibility and heat stability than metal solders, thereby avoiding cracked joints. One that also has good thermal conductivity should be ideal for cooling – such as bonding processors to heat sinks. To be sure the new adhesive is perfect for your manufacturing project however, always consult with an appropriate specialist, such as

3D applications

The company that produces the new adhesive is Graphene 3D Lab Inc., whose name gives away their other main focus. There are many signs that the destiny of graphene is interwoven with 3D printing technologies. For example, American Graphite Technologies formed a partnership with the Ukrainian Kharkov Institute of Physics and Technology (KIPT) in 2013, to research graphene’s use in 3D printing, a graphene-infused printer powder has been available for commercial use since 2015, and a related project at Harvard has 3D-printed a fully functioning lithium ion battery, smaller than a grain of sand.
