Cold galv paint or cold galvanizing paint is used for painting steel. It is rich in zinc due to a mixture of zinc dust with several inorganic and organic binders. This type of paint is designed to protect metals from corrosion and other harsh environmental situations. The paint which is rich in zinc can be easily applied to various shapes and sizes of steel. However, it may occur difficult to apply the cold galv paint due to the low availability of paints rich in zinc for metals. To know more about cold galv paint, read below-
Characteristics of Cold Galv Paint
These are the following characteristics of cold galv paint-
- Protection from Corrosion
Cold galv paint is found in two types- organic zinc and inorganic zinc paints. The inorganic zinc paints have the ability to sustain a temperature of up to 700F. Also, they have a high density and do not blister easily. On the other hand, the organic cold galv paint can only sustain a temperature of up to 200-300F. Also, they are less effective than inorganic zinc-enriched paints.
- Apply Multiple Coats of Cold Galv Paints
It is easy to paint cold galv paint on the metal components. The zinc enriched paints have about 65-95% of metallic zinc. It can be easily painted using brush or spray. Also, to prevent the settling of the zinc dust, it is best to keep the feed lines short.
- Cathodic protection
The cold galv paints also provide cathodic protection to the metals. To get the cathodic protection, the zinc dust should have a high concentration to provide conductivity between the steel and zinc particles.
Benefits of Cold Galv Paint
To know about the benefits of cold galv paints, you must read the following-
- Cold Application
The application process of cold galv paint is very easy. You just need a brush, spray, or even a roller. Alongside, it requires no heat because it can be applied directly on the site at normal temperature.
- Easy Process for Topcoat
You can directly paint the top cost without much hassle. Otherwise, for hot-dip galvanising, you have to clean the surface thoroughly and prepare it for the coat. You have total control over the quality of the zinc coat. Also, it is non-hazardous.
- Flexibility
The cold galv paint is highly rich in zinc that provides flexibility to the metal or steel pipes. It means that if you can apply the pain on the bend of the steel pipes. Thus, it is more flexible than other types of paints.
Where You Can Apply Cold Galv Paint
These are the following application of cold galv paints-
- Solar Structures- The solar structures consist of steel structures which are generally painted with cold galv paints to increase their durability.
- Base Structures and Frames- The base of a building that require steel structures are also painted with cold galv paints. It provides strength and protects from corrosion.
- Tower Structures- The tower structure broadly comprises bare steel. Cold galv paints are also used to paint tower structures as well.
Conclusion
The cold galv paint can be easily applied to metal components of different shapes and sizes. It is also used a primer with two or three coats. Along with that, it is also used as a substitute to repair the coating of hot-dip galvanised coatings. However, the hot-galvanising methods require the metal to melt at a high temperature. It also lasts up to more than 50 years. Hence, cold galv paints are easy to use and protect the steel structure from corrosion for a significant period.
