Graphene Coating: introduction and market status - Page 11

UK-based planarTECH has launched an equity crowdfunding campaign on Seedrs, as part of Graphene-Info's Graphene Crowdfunding Arena. planarTECH aims to expand its current business and also initiate new graphene endeavors. Investors are now able to participate in this financing round.

Here's our interview with planarTECH's co-founder and CEO, J. Patrick Frantz - who explains the company's technology, business and future plans.

Micro Powders, in collaboration with Garmor, recently launched GraphShield 730, a next-generation graphene-based anticorrosion additive for powder coating applications.

GraphShield 730 uses Micro Powders’ wax composite technology to deliver a high loading of Garmor’s unique edge functionalized graphene product, enabling the delivery of an advanced nanomaterial into coating formulations safely and effectively without any changes needed in the customer’s production process. Graphene imbues the final coating with significantly enhanced corrosion resistance on both bare and treated cold rolled steel, with up to 50% reduction in corrosive creep.

Scientists from Chung-Ang University, Korea, led by Prof Hyungbin SonKorea, have observed a unique way in which graphene forms a hybrid layer that prevents copper corrosion.

A challenge with using copper is that its surface oxidizes over time, even under ambient conditions, ultimately leading to its corrosion. Thus, finding a long-term method to protect the exposed surfaces of copper is a valuable goal. One common way of protecting metal surfaces is by coating them with anti-corrosive substances. Graphene is studied extensively as a candidate for anti-corrosive coating, as it serves as a barrier to gas molecules. But, despite these properties, graphene sheets have been said to protect copper from corrosion only over short periods (less than 24 hours). In fact, surprisingly, after this initial period, graphene appears to possibly increase the rate of copper corrosion, which is completely in contrast to its anti-corrosive nature.

Talga Resources has announced the commencement of a new large-scale commercial trial of its Talcoat graphene additive for maritime coatings. At the core of the Talcoat product is Talga’s new patent pending graphene functionalization technology in the form of an on-site dispersible powder that adds graphene to paints and coatings.

Following the former trial, ans supported by the same ship owner, Talga has provided its graphene additive to enhance a primer coating successfully applied over a sizeable area of a second large container ship.

Talga Resources, advanced battery anode materials and graphene additives provider, has announced a commercial-scale trial of a graphene-enhanced coating applied to a 33,000 tonne container ship.

The 700m² coating of the cargo vessel’s hull is part of advanced testing of Talga’s functionalized graphene (Talphene) additive as a performance booster for existing commercial marine coatings.

Applied Graphene Materials has announced that its graphene primer product is now on sale at Halfords, the UK's leading retailer of motoring, cycling and leisure products and services.

James Briggs (JBL) has also launched its Hycote graphene anti-corrosion primer, developed in collaboration with AGM, for sale on Amazon, and through Tetrosyl Express, the largest supplier of car care, parts and accessories in the UK.

XG Sciences, designer and manufacturer of graphene nanoplatelets and advanced materials containing graphene nanoplatelets, and Terrafilum, an eco-friendly, high quality filament producer for the 3D printing industry, announced a joint development agreement to develop, produce and market 3D printing filaments and coatings using graphene-based materials.

Chris Jackson, President of Terrafilum, points out, "The full potential for 3D printing is starting to be unlocked. The addition of XG's graphene formulations into our eco-friendly filaments will transform products allowing a greater variety of parts to be created at faster production rates using less energy."

PC gear company Cryorig has introduced its low-profile CPU graphene-enhanced cooling system for small form-factor PCs that can dissipate up to 125 W. The Cryorig C7 G is among the smallest coolers for higher-end processors available today. To make C7 G's high performance possible, Cryorig applied graphene coating on the heatsink.

As demands arise for higher-performance components, cooling designers are creating low-profile coolers rated for TDP levels of 95 W of higher. To maximize efficiency of such devices, manufacturers use copper for heatsinks, many heat pipes, and large fans. Cryorig decided to go one step further and applied graphene coating to the radiator’s fins. Thermal conductivity of graphene is considerably higher than thermal conductivity of aluminum or copper, so applying it on the fins could theoretically improve cooling performance.

The Tata group is a global enterprise, headquartered in India, comprising over 100 independent operating companies. Tata Steel, the flagship company of the Tata group, is a Fortune 500 Company with immense global reach. TV Narendran, Managing Director of Tata Steel, provided updates on the Company's graphene R&D business.

Tata Steel is working with graphene as part of its plan of focusing on developing advanced material to protect its margin and bottom line. Its Graphene Development Center has recently produced corrosion-resistant graphene paint and supplied graphene powder to renowned tyre companies. It has also demonstrated the potential of graphene inks, which are used in the printing of train tickets, plane boarding passes, and RFID (radio-frequency identification) tags.

Australia-based graphene and data analytics company, Imagine Intelligent Materials, has developed an integrated sensing solution that uses graphene coatings and edge-based signal processing devices to collect data from objects with large surface areas.

Proven over areas as large as 4,000 square meters, the system gathers data such as pressure, moisture, stress and temperature and is aimed at industrial and consumer applications in the IoT market.
