Sparc Technologies Limited (ASX:SPN) has received positive results from ongoing coatings test-work performed with the University of Adelaide.
Testing to date confirms that a range of Sparc graphene additive formulae added to coatings significantly improves anti-corrosive performance.
The results, when compared to a control coating (without graphene), showed:
- Up to 73% performance improvement inscribe creep (corrosion); and
- Up to 19% performance improvement in adhesion.
These results deliver another milestone in the development of a range of graphene-based additives, particularly for use in marine and protective coatings.
“Extremely encouraging”
Sparc managing director Tom Spurling said: “The results from this round of test work are extremely encouraging.
“Test-work has been undertaken to conform to ISO standards which enables us to target our vast industrial customer base to assess the results objectively.
“Sparc will now use the data derived from this test-work, build on it, and continue to refine the optimal graphene formulation for the coatings additive so as to maximise performance.”
Performance evaluation
Using ISO testing methodology, Sparc has evaluated the performance of a range of graphene-based additives produced using variations of raw material sources, processing methods and graphene quantities.
The testing has highlighted the performance benefits of graphene additives in general, with a number of the additives generating significant improvement in adhesion and/or scribe creep results at very low graphene additive levels.
Improvement in adhesion of up to 19% was observed in single coat systems and reduction inscribe creep of up to 73% in three coat systems.
In the context of Sparc’s targeted customer industries, these results represent a potential for substantial cost efficiencies and performance improvements.
