UV Powder coating Drying Time is under One minute

Yes its true UV powder coating is the next game changer in the powder coating industry where you can dry UV powder in less than a minute compared to traditional powder coating which takes between 20 -25 minutes to dry. A UV-cured powder system can produce more material in a given period of time. This results in an increased operating capacity, reduced WIP inventory, lower cost of quality, less energy usage, and increased profits per hour. All of these factors lead to a higher ROI. UV-curable powder coating is faster and uses less energy than other finishing processes. This key benefit allows you to coat more products in less time while using less energy without damaging the substrate. This increases productivity and reduces running costs.

UV powder is  safe to use, and can easily be recycled. Manufacturing and use of UV-curable powder coatings do not require any permits, special air handling, operator breathing devices or flammability restrictions or controls.Material handling and cleanup are very simple and easy. A spill can be swept up or vacuumed with no residual damage to equipment or property. Leftover powder can also be recycled. UV powder coating technology can be used in automotive components, industrial products, steel furniture, plastic parts, composites etc.

Why Distribution Transformers Must be Powder coated And Not Painted?

Many distribution transformers up-to 220 kVA are designed to have fins all over the tank. These fins have upto 440 mm depth and have around 50 mm gap between them.It is difficult to find a spray painting gun that can penetrate the paints between the fins and deposit effectively protecting it against corrosion.These transformers are mounted on top of a post /poll and are subject to hot, humid, rainy and harsh weather conditions through out the year. The chances of repainting are very less hence the quality of coating should be able to withstand these conditions.

The conventional practice is to have a 3 coat paint system with manual shower coating as the primer coat followed by intermediate and top coat using spray painting. This 3 coat system is an efficient process wasting a lot of paint, not environmental friendly and does not cover all the surfaces between the fins.Hence in order to obtain C4 or C5 quality standards Prism has introduced a special technology where you can powder coat the distribution transformers, tanks, lids and conservators.When you powder coat the transformers you reduce on your running costs as you can reuse the powder rather than disposing it. With powder coating you also get better protection compared to painting especially when it is exposed to harsh weather conditions.
