Heavy duty anti-corrosion coatings may exhibit layering during long-term storage,especially in large volume paint barrels,resulting in uneven coating or unusable coatings.It is mostly a two component coating and must be stirred evenly before use.In order to explore the influence of different mixing methods on the performance of coatings under large volume,homogenization mixing experiments were conducted on coatings from three factors:mixer structure,mixing time,and mixing speed.The viscosity of the coating after mixing and the adhesion of the coating after curing were measured.The experimental results were analyzed to verify the influence of different stirring methods on the performance of the coating under large volume.
