There are some coatings and coating systems for zero-low VOC (volatile organic compounds) in anti-corrosion coatings.
High solid and non-solvent coatings are widely applied in heavy-duty coating systems. In other case, these coatings are taken into service to avoid solvent poisoning in a closing up environment.
As old style water-borne coatings are too hard to show good rust preventive performance for steel structures, and the drying or the hardening of wet film is influenced by low temperature, high humidity, rains or other weather conditions, they are seldom applied for anti-corrosive use.
In recent years, some new drying or hardening techniques of water-borne coatings have been developed.
Now we are able to get some water-borne coatings which perform excellent corrosion and weathering resistance.
