FOCUS ON ZINC‐2: Metallic zinc paints Available to Purchase

There are many ways of protecting ferrous metals with zinc, and coating them with paint incorporating metallic zinc powder as a pigment is the most versatile. Although hot dip galvanizing remains the standard by which other forms of protection are judged, zinc paints have some very great advantages:— they are easy to apply, which may be in factory or on site; the thickness of coating can be controlled to that required for a given duration of protection; there is no limit on the size or weight of the object which can be protected (both the world's biggest ship and largest building are protected with zinc rich paints). They are preferable to galvanizing where welding or flame cutting operations are carried out subsequently, and can be made to withstand temperatures up to dull red heat.
