HG/T 5573 Graphene zinc powder coating performance testing scheme [with economic file instrument parameters]

The HG/T 5573 "Graphene Zinc Powder Coating " standard is applicable to coatings composed of graphene materials, zinc powder, inorganic or organic paint bases, etc. It is not suitable for zinc powder coatings with a non-volatile minute metal zinc content of less than 30%.

According to the HG/T 5573 standard, the graphene zinc powder coating needs to test the following properties: state in the container, non-volatile matter content, density, metal zinc content in non-volatile matter, pot life, qualitative properties of graphene materials, drying time, Workability, coating appearance, impact resistance, pull-off adhesion, continuous condensation test, neutral salt spray test, etc.
