Chemical Resistant Coatings
Chemical permeation is a major issue in markets like chemical processing and storage, oil and gas, marine and transportation, where both internal and external surfaces are exposed to chemical attack.
Prolonged contact from full submersion, splashes, spills and fumes from a range of chemical substances can lead to visual discolouration, gloss reduction and blistering, all of which can have a negative impact on coating performance. As a result, manufacturers constantly strive to develop surface protection systems that can resist chemicals and protect the substrate from contamination.
Graphene nanoplatelet dispersions enable high-performance paints and coatings to more effectively protect a substrate against harsh chemicals in highly aggressive environments.
Why Innovate with Graphene?
Outstanding barrier performance
Flexibility in formulation for improved physical properties
Cost-competitive solutions
How Does Graphene Compare?
Example Coating Performance in Lactic Acid – 28 Day Immersion Testing
Example Coating Performance in Sodium Hypochlorite – 28 Day Immersion Testing
Less Really is More!
The uplift in coating performance was seen with as little as a 2.5% addition of UM’s Genable graphene nanoplatelet dispersions, compared to a much higher 20% loading level of Glass Flake.
By reducing the amount of filler required in the coating, it is also possible that secondary benefits could be achieved such as increased substrate adhesion, higher impact resistance and improvement in flexibility.
Replacing traditional filler content with a small amount of UM’s high-performance graphene additive not only offers performance improvements from a cost-competitive solution, but enables greater flexibility in formulation to allow coating innovators to develop their next generation of chemical resistant paints.
The Performance Advantages of Graphene Nanoplatelets
Epoxy Coating Chemical Resistance Comparison
In comprehensive tests, UM compared the chemical resistance performance of graphene-enhanced epoxy resin coating formulations against an industry standard glass flake-filled alternative.
The coatings were immersed in a range of acidic and alkaline solutions to enable a broad understanding of performance, with both the graphene-only coatings and graphene-glass flake hybrid systems significantly outperforming the standalone traditional glass flake additive.
Not only was the superior performance visually clear with less blistering, but the results also showed a marked improvement in gloss retention and hardness with the addition of graphene.
UM offers a selection of different Genable graphene dispersions optimised to meet a variety of application needs.
Our dispersions have already demonstrated proven anti-corrosion performance advantages; the latest chemical resistance results offer users yet another way to innovate, perform and stand out with a graphene-reinforced paint or coating.
