Sparc Technologies Limited announced positive results from its ongoing coatings test work performed with the University of Adelaide. These results deliver another milestone in the development of a range of graphene based additives for use in Marine and Protective Coatings. 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 current test work addressed adhesion# and scribe corrosion creep.
