Why use protective coatings

If regular maintenance is not performed, underfilm corrosion begins and the coating can fail in a relatively short period of time. There is no cathodic protection provided by paints and powder coatings, which limits their time to first maintenance to ten years or less in most environments. Both paint and powder coatings can be used in conjunction with hot-dip galvanizing, known as a duplex system.

The two coatings work in synergy to provide surperior corrosion protection, while allowing a specifier to suit any aesthetic preference. Login Close. Paint Publications. Necessary Required.

They also dissolve other raw materials and are the carriers of the binder. The most common solvents are white spirit, xylene and water. Solvents are only used in wet paints and not in powder coatings.

Additives are substances that are added to the paint or powder coating in small quantities to impove or modify its properties. Additives are used to prevent corrosion or growth, as a thickener, as a preservative to prevent the coating from degrading in the tin, to prevent foaming paint, and to make the paint flow out and give a smooth surface.
