How to Distinguish Real from Fake Eco-friendly Water-based Anti-corrosion Paint

Anti-corrosion paints are varied: by composition - epoxy, polyurethane, acrylic, inorganic, perchloroethylene, chlorinated rubber, high-chlorinated polyethylene; by use - pipe, marine, metal, furniture, automotive, rubber; by solvent - water-based or oil-based. Chemically they are mixtures of hydrated silicate minerals whose main oxides are Al2O3 and SiO2; the closer the Al2O3 content and Al2O3/SiO2 ratio are to the kaolinite theoretical value, the purer the clay. 1) Anti-corrosion coating is not paint - many confuse them; the coating is water-soluble while paint contains oil. Environmentally, more consumers choose water-based coatings because paint odor is pungent and unhealthy. 2) Anti-corrosion coatings have fewer colors than paint, so paint decorates better, but the coating protects objects far better and is thick, needing specialized application rather than an ordinary brush. When choosing: match the environment (acidic -> phenolic resin; alkaline -> epoxy), consider constructability (use air-dry cold-cure types for non-brushable items), and ensure the primer/base match to avoid micro-pores that let corrosion through (e.g., perchloroethylene coating with phosphating primer).
