raphene can now be produced on large industrial scale. Most of these
processes generate few layer graphene. This sets the focus on how
graphene can be incorporated into industrial applications. The Sixth Element
has established a proprietary process to manufacture different types of
graphene with specific designed properties for different applications.
Products of Sixth Element are registered according REACh. Research on
how using graphene in coatings started 2013 focusing on reducing zinc in
solvent based corrosion protection primers. In standard primers with high
zinc content, zinc acts as cathodic sacrifice layer, as zinc is the more ignoble
metal, therefore protecting the underlaying metal substrate. When the zinc is
oxidized, the resulting zinc oxide builds up a barrier, which prevents the attack
of the surrounding media to the metal substrate. The idea was to design a
graphene type, being electrical conductive enough to support any cathodic
function of the systemand able to act as a barrier without producing a battery
cell. A further requirement was that such a graphene can be processed
with standard equipment used in the coating industry. Cooperating with
an industrial partner in China, Toppen Co, the graphene type SE1132 was
developed, a few layer graphene with a medium conductivity. Addition of 1%
SE1132 to an epoxy primer system and reducing the zinc content to 25%
(basedon dry substance) showsignificant improvements in salt spray testing
and water condensation testing compared to a standard zinc rich epoxy
primer. The results have been confirmed by measuring the corrosion current
of such a system. The 1% addition shows the lowest current. In China Sixth
Element has received a patent for this development. Based on independent
tests of Chinese authorities the system containing 1% graphene (based on
dry substance) is approved for off-shore applications. The system was first
applied to protect the steel construction of an off-shore wind energy tower in
2015. Meanwhile more off-shore projects have used this system. Contrary to
this, in Europe the development of such systems is in the prototyping stage.
Based on these findings, prototypes of water-based and powder coating
systems have been developed; showing that graphene also in these systems
enhances corrosion significantly. Development of commercially available
products is ongoing. An update on latest developments will be given at the
conference

Biography
Bernhard Münzing has started his career at BASF
selling fibre reinforced prepreg-systems mainly to
the aerospace and sports industry, being an Eco-
nomic Engineer. He then joined L. Brüggemann
responsible for Materials Management and intro-
duction of new products to the market. After short
period as Sales Manager for a coating company, he
worked for more than 17 years for GELITA, world
leading gelatine manufacturer. Covering all appli-
cations areas for gelatine, he helped customers to
adopt the gelatine products during the critical phase
of the BSE disease, followed by a position in busi-
ness development for more than ten years. Aside
that he was the responsible key Account Manager
for one of the largest GELITA customers in Asia.
Since Jul’ 2016, he is Sales Director of The Sixth
Element, a leading supplier of different graphene
products, responsible for all markets outside China
with focus on EMEA region.
