Graphene 3D Lab develops carbon-silver adhesive, files patent

2017-03-09 09:29 ET - News Release

Mr. Daniel Stolyarov reports


Graphene 3D Lab Inc. has completed the development of an innovative carbon-silver adhesive material and filed a provisional patent application to secure the intellectual property rights. This new material is a highly electrically conductive epoxy adhesive based on the proprietary combination of carbon and silver fillers, and other additives. The company is planning to add a product based on this formulation to the G6-Epoxy line of adhesives.

The key unique feature of this material is the low weight load of silver needed to achieve high electrical conductivity. According to results of internal testing, the volume resistivity of the material is 0.007 centimetre and can be achieved with a silver weight load as low as 40 per cent. Most commercially available silver-based adhesives typically require a 75-per-cent to 80-per-cent silver load by weight to attain conductivity.

Silver is currently priced near $550 (U.S.) per kilogram and is the major factor contributing to prices of silver-based adhesives ranging from $600 (U.S.) to $3,000 (U.S.) per kilogram. The company believes that the invented formulation that has a significantly lower silver content, while still providing similar levels of conductivity, will result in a product that will be well positioned to compete with current commercially available conductive silver-loaded epoxies.

In addition, the higher content of the epoxy polymer in the formulation of this product offers the additional competitive advantage of improved bond strength to a wide variety of substrates including glass, plastic and fabrics. Low load of fillers allows tailoring the formulation for better flexibility making this material well suited for wearables, smart textiles, sensor networks and medical devices.

The electrically conductive adhesives (ECA) market was estimated to be $1.2-billion (U.S.) in 2015 (according to IDTechEx) and is projected to reach an estimated $2.53-billion (U.S.) by 2021, a compound annual growth rate of 8.48 per cent from 2016 to 2021, according to the report by the market research firm MarketsandMarkets. ECAs are considered to be a replacement for traditional tin-lead solders, and their fast growing demand is driven by the increase in the use of electronic components in various industries such as aerospace, automotive, 3-D printing, consumer electronics and medical devices.

The company invites commercial enquiries for this product.
