Powdercoating
Powder coating is an alternative, environment friendly method of applying Paint.
Normally, to apply a 'wet' Paint, solvents are required to allow the Paint to become a liquid thus allowing it to be applied to the object to be Painted the solvent also make the paint sticky, causing it to adhere to the surface.
With Powder Coating, only the Paint solids are sprayed onto the product, in an atomised powder form.
The Powder is drawn to the product and adheres to the product due to an electrostatic charge applied to the Powder during spraying.
The Product, thus covered with the Powder Paint is then heated (to around 200 degrees Centigrade) in an Oven, wherein the powder fuses (melts) on to the product and thus forms a smooth, tough and resilient coating.
What are the benefits of Powder Coating?
High Quality. Because the powder is fused onto the product, it has excellent scratch resistance properties. It also has a pleasing 'smooth' appearance and forms a sealed skin around the product thus minimising corrosion risk.
Recoverable. Unlike wet paint, 'Over spray' powders can be collected and re-used! When you consider that in any paint spraying system, only around 50% of the paint for powder actually lands on the job, then large savings are clearly possible if the over spray can be re-used.

Simple Automation.
Because powder is applied electrostatically, is fully recoverable and is easily cleaned away, powder is ideally suited to simple, automatic application thus minimising labour requirements.

All crocodillas products are powdercoated twice for excellent climatic interface
First powder is a long life Zinc primer which is then allowed to cool before a high gloss finish extra life powder is applied
Tested to worldwide standards
Extra Life powders
Offers peace of mind because we have extensively benchmarked our systems against ISO12944: 1998*, which is the worldwide standard for the corrosion protection of steel structures by protective paint systems.
Suitable for differing environments
Extra Life powder coating systems are suitable for most types of light industrial applications.
Externally, these include urban and industrial atmospheres, moderate sulphur dioxide pollution and coastal areas with low salinity.
Internally, the most aggressive are production rooms with high humidity and some air pollution – e.g. food processing plants, laundries, breweries and dairies. (The life expectancy will vary between various internal and external environments). |
