Important results from the project
1-Selection of graphene grade 2-Preparing graphene dispersions. 3-Analysing and selection of the graphene dispersions using optical microscopy 4-Incorporation of graphene dispersion into the GreenCoat® BT paints by SSAB 5-Application of the graphene-incorporated green paints and investigation of anti-corrosion properties of the final coatings by SSAB
Expected long term effects
The two project partners, RISE (RISE Research Institutes of Sweden AB) and SSAB (SSAB AB) closely collaborated in the incorporation of graphene into the clear coat and testing. In this study, graphene is incorporated into SSAB patented green anti-corrosion coating (GreenCoat®) formulation to study the performance of graphene containing anti-corrosion coating on hot-dip galvanized steel. Our result showed that incorporation of graphene flakes into GreenCoat® formulation resulted in improved anticorrosion performance when applied on hot-dip galvanized steel substrates
Approach and implementation
WP1. Selection of graphene grade and preparation of graphene dispersions by RISE. WP2. Incorporation of graphene dispersion into the GreenCoat® BT paints by SSAB WP3. Application of the graphene-incorporated green paints and investigation of anti-corrosion properties and durability of the final coatings by SSAB.
