Gas Catalytic Oven Can Cure Powder in 3-4 Minutes

Yes its true , gas catalytic oven can cure the powder with 3-4 minutes. it can also be used as a booster oven to bring down drying times and reduce the length of the conventional powder curing oven and reduce on investment costs. It can be retrofitted into an existing powder coating plant/line. Gas catalytic oven reduces your fuel/energy/running costs by 50% and increase your productivity. The gas catalytic oven uses a special radiation heat transfer technique which heats the powder and not the metal. Radiation heat is created by oxidizing the gas either LPG or natural gas using a catalyst. Gas catalytic ovens can be used on flat as well as complex shaped parts.

Prism has installed many gas catalytic ovens  around the world as well as in India along with its powder coating plants and Painting lines.

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.

Things to Consider in a UV Powder Coating Line

Over the years paints are formulated to either cure at ambient temperature or at elevated temperatures. This depends on the paint formulation. Paints which are cured in convection oven normally take between 20-30 minutes and the same paints are cured within 3-4 minutes in IR ovens. When you use UV powder system along with UV powder it takes less than a minute. This reduces your energy consumption drastically in your powder coating line/plant. This becomes a game changer. UV powder is generally followed by IR gel zone .UV technology can be used on metal, plastics, wood MDF, composites etc. The finish achieved with UV powder with far more superior compared to traditional powder coating. UV lighting technology together with the right paint formulation could offer the potential to expand to to other industries.The industries that can benefit using UV powder coating technology include automotive components, all types of steel furniture, utility vehicles, aerospace, industrial products, healthcare and many more. Prism surface coatings is a turnkey system supplier of complete UV powder coating line and systems. Prism can also supply you the UV powder.

What is UV Powder coating and its Advantages?

UV cured powder coatings are an industrial finishing technology giving a resilient and durable finish to a variety of materials and products. UV cured powder coatings are available in many colors, glosses and textures and formulated to meet specific performance requirements. UV powder coatings are produced in the same manner using the same equipment as thermoset
powder coatings – blended, extruded, chilled, chipped, milled, classified, sieved, and packaged. Prism is the turnkey supplier of complete UV powder coating plant and we also help you supply with the powder.

Advantages of UV Powder Coatings:

1.Environmentally Friendly
UV powder coatings contain no volatile organic compounds (VOCs), or hazardous air pollutants (HAPs), are solvent free, and non-toxic. They contain no chemicals or compounds that can damage the environment and waste materials can be recycled.

2· Efficient Process/Speed of Curing
UV curable powder coatings cure faster and use less energy than other finishing processes. More parts are finished in less time.

3.Ability to Coat Heat Sensitive Materials
UV cured powder coatings melt at lower temperatures and cure faster than other coatings. This advantage makes it possible to powder coat “heat sensitive” materials like wood, medium density fiber board (MDF), plastics, composites, and carbon fiber without damaging the substrate.

4. Small Plant Footprint
A UV powder application system uses less plant floor than other paint systems. Footprint could beas small as 185 square meters, potentially less depending on type of product finished and system design.

5. Ease of Material Handling
UV powder is safe to use and is easily recycled. Use of UV curable powder coatings does not require any permits, special air handling, operator breathing devices, or flammability restrictions. Faster and Greater Return on Investment
A UV cured powder system can finish more material in a given period of time. The benefits of a fast system are an increased operating capacity, reduced work in process inventory, lower cost of quality, less energy usage, and increased profits per hour – generating a faster and greater ROI.

 

Best Paint Spray Gun to Paint Steel Wheels-Magic Painter Gun

Yes the ideal paint gun to paint steel wheels is the magic painter gun. The magic painter gun is a gun that does not use compressed air and saves upto 60% paint. The special feature of this gun apart from the paint savings is its penetration capability to reach into grooves and crevices of the wheel which otherwise cannot be reached by electrostatic guns because of Faraday cage effect due to consistent grounding is required. Also paint resistivity has to be maintained. The cost of maintaining electrostatic guns are also very expensive and there is a risk of operator safety. With the magic painter gun no such earthing or grounding is required and it can penetrate to all the grooves and crevices of the wheel. We have supplied to wheel companies worldwide and they are successful in saving huge amounts of paint and money. The magic painter gun gives a transfer efficiency between 85-90%.
