First Graphene Limited provided an update on its work with University of Adelaide (UoA) on FireStopTM fire retardant coatings. Background: Development of the FireStopTM product is being conducted in collaboration with the University of Adelaide as part of the Company's participation as a Tier- 1 member of the ARC Research Hub for Graphene Enabled Industry Transformation. The Flame Retardancy market is worth $8 billion in 2016. The most valuable segment is in plastics $5.7 billion; followed by textiles $1.1 billion and wood/paper $0.33 billion and coatings/paints $0.31 billion. Test Work Conducted: Following the successful development of a fire-retardant coating formulation the product was tested according to the UL94 standard test method with simultaneous testing of a commercially available competitor product. Performance in the UL94 test was evaluated in relation to the thickness of coating required for effective fire protection. Sample Preparation for UL94 Testing: Coating formulations were applied to untreated balsa wood test pieces with a paint brush. The coating thicknesses were controlled by using a fixed number of coats. The coating thicknesses were then measured after deposition. Balsa wood is used in the test specimens because of its high flammability. Test specimens were prepared with the following dry thicknesses: 1. Untreated balsa wood. 2. First Graphene FireStopTM at 450 microns. 3. Competitor coating at 700 microns. 4. First Graphene FireStopTM at 700 microns. 5. Competitor coating at 1020 microns. Results of UL94 testing: First Graphene FireStopTM performs well at both 450 microns and 700 microns; meeting the UL94-V0 requirements at both thicknesses. The competitor product does not meet the UL-94-V0 standard at a coating thickness of 700 microns and requires a much thicker coating, in this case, measured at just over 1000 micron (or 1mm) to reach the UL94-V0 standard. Summary: The graphene based FirestopTM product offers a new approach to fire retardant coatings which facilitates fire protection using thinner coatings - reducing both coating material consumption and labour costs during application. This performance is enabled by the excellent gas barrier and thermal conductivity properties of First Graphene graphene additives. Future work: While these initial tests are very encouraging, the University of Adelaide continues to carry out performance testing using recognised test procedures, including LOI (Limiting Oxygen Index) to confirm these findings. This will be followed by independent verification by an external test house such as CSIRO.
