What is the chemical name for a green coating on a coin?
For copper or some copper alloys coins the coating is hydrated copper carbonate.
How can use styrene acrylic in coating?
Styrene acrylic can be used in coating applications by mixing it with other additives and resins to improve adhesion, durability, and chemical resistance of the coating. It can be applied as a water-based emulsion, delivering low-VOC benefits and easy clean-up. When properly formulated, styrene acrylic coatings can provide good film formation, color retention, and weatherability properties.
Is rusting of a can physical or chemical process?
it is a chemical process, as rust is the chemical reaction of the oxidation of iron. rust, or iron oxide, is formed when iron reacts with oxygen in the air. this can be prevented by either already reacting the iron with something like sulphur, or by coating the iron with a thin inert layer such as oil or plastic.
