First Cool Shades Collection Project secured by Jotun Powder Coatings UAE
The Abu Dhabi One Tower is the first project world wide that has specified The Cool Shades Collection as announced by Jotun Powder Coatings UAE in February.
Located in the Capital City of Abu Dhabi, the total quantity of powder to be used in this project
will be 6MT. Supply of powder coating has already started and according to A.P.G., the architechural firm
handling the project, the Abu Dhabi One Tower is on track to be completed by end of 2011.
The Cool Shades collection has attracted a lot of interest from architects, specifiers and facade consultants who see this product as the way forward to improve sustainability and 'green' credentials of their facade designs. In Feb 2011, Jotun Powder Coating UAE was the gold sponsor of the Facade Design and Engineering Summit 2011 held in Dubai, in which the Cool Shades Collection was highlighted.
The event is an annual one and is focused on the facade industry and its needs. Among the participants in event were industry experts comprising of leading developers like Emaar and Sorouh; Architechural firms such as RMJM and Benoy and Facade specialists such as Arup and Ramboll, to name a few.
UAE General Manager Ram Ramnath and Architechural Specifications Manager Monesh Aidasani conducted a presentation entitled "Advance in Powder Coating technology for the aluminum facade industry" which showcased how Jotun Powder Coating has kept pace with the exacting demands of the facade industry on the three most important dimensions - performance, aesthetics and sustainability.
Architectural Powder Coatings
Jotun Powder Coatings, one of the world’s leading producers and suppliers of powder coatings, has launched the ‘Cool Shades Collection’, a new collection of energy-savingand environmentally friendly powder coatings formulated to reduce the temperature of aluminium building components that are exposed to the sun, thereby effectively contributing to lowering buildings’ energy consumption and cooling costs.
The unique range is based on heat management pigment technology that reflects the infrared energy to allow colours to maintain their vibrancy. The ‘Cool Shades Collection’ offers a wide range of colours to match both modern and traditional architecture, and is in an ideal application for window frames, curtain walls, shutters, louversand wall panels. Furthermore, the new collection is available in industry-leading high performance polyester powder coatings Corro-Coat PE-SDF Super Durable, as well as the standard architectural grade Corro-Coat PE-F Façade. “Sustainable architecture ensures that what we do today will not limit opportunities for future generations, and we have created ‘Cool Shades Collection’ based on this belief,” said Claudio Lurili, Divisional Marketing Director of Jotun Powder Coatings. “The environmentally friendly properties of our new range speak of our commitment addressing the issues pertaining to green building, green living and constructions of buildings that enhance quality of life and minimize environmental impact.”
As more and more structures are being completed in accordance to green building codes, with aims to achieve sustainability and increase efficiency, solutions that lessen the buildings’ energy consumption are witnessing increasing demand. Complementing the most important green construction and maintenance processes, Jotun’s ‘Cool Shades Collection’ makes a real difference on indoor temperature by lessening heat build up indoors, thereby contributing to reduce the use of cooling systems that use precious resources and energy. “The ‘Cool Shades Collection’ is another testament of our strong support for sustainable architecture.

Test Method and Equipment
The physical performance of any powder coating on a substrate is extremely dependent upon the adhesion forces between the two. Adhesion is very dependent upon the cleanliness of the substrate, the appropriate selection and maintenance of pretreatment, and the proper melt and cure of the coating powder. Inadequate adhesion will affect properties such as impact, flexibility, slow penetration, outdoor durability and corrosion resistance. Adhesion may be tested by several different methods. A commonly used technique is the cross hatch and tape method. In this method, crossed or lattice cuts are made through the coating. Adhesive tape is then applied to the cut coating and then remove quickly. The coating adhesion is then rated by its ability to remain on the substrate and to not be removed by the tape. Through this method offers a very quick determination, a crosshatch failure only indicates very poor adhesion.
Measurement of adhesion by Cross-cut
Test and tape pull off
This standard specifies a procedure for assessing, by means of simple empirical test, the resistance of a powder coating to separation from substrate when a lattice pattern is cut into the coating, penetrating through it to the substrate. A tape with specified adhesion strength is put over the lattice pattern and peeled off.
This method is an unauthorized abstract of ISO 2409
Cross – cut Tester
Hold the cutting tool face in a plane normal to the test panel surface and make cuts with a length at least similar to the width of the tool. Make new cuts overlapping the original cuts and at 90o to them so that a lattice pattern is formed (25 squares)
Use a cutting rate of 2-5 cm /sec and make the cuts in an even. All cuts must penetrate through to the substrate but shall not cut too deeply into the latter.
Brush the panel lightly with the polyamide brush five times forwards and five times backwards along both diagonals of the lattice pattern. Press an adhesive tape onto the lattice pattern. Press firmly to avoid air entrapment between tape and substrate. Pull the tape of with a firm movement, keeping an angle of 45o between tape and substrate.
Powder Coating Facades Maintenance
A maintenance –free surface coating for the construction industry is up till
now unavailable in the marketplace. No maintenance-free surface coating for
the construction exists. This includes products specially designed for parts of
the world where climatic conditions put extreme strain on the exterior coating.
Correct maintenance has a major influence in maintaining the aesthetic appearance of a coating, thus expanding its year of service. Since the coating is usually exposed to a variety of environmental conditions, depending on what weather zone in the globe it is exposed to, maintenance should be handled differently in different parts of the world.
Periodical Cleaning and Routine Maintenance (Cleaning frequency)
Powder Coated Objects or Components Used Outdoors
Cleaning is typically used to remove dirt and stains to maintain the aesthetic impression of the coating. When the coated objects or components are located in maritime sites, highly polluted areas, aggressive stains may result on the coating surface and the gloss will gradually fade away. This may accelerate degradation of the coating’s surface through corrosion, and will reduce the coating’s years of service.
Cleaning is generally recommended at 6-month intervals; however, in highly exposed areas the frequency should be increased, depending on the severity of climate conditions on the coated object or components. Ordinary dirt and stains can be removed using a household neutral detergent (ph 5 to 8), diluted with water. The cleaning agent should not contain abrasive materials or solvents as they might have an adverse effect on the coating.
Powder Coated Objects or Components Used Indoors, Behind Glass
Typically, powder coated objects or components located or placed behind glass show no deterioration. However, their visual and aesthetic appearance might be affected by dust, dirt and splashes. It is recommended that these objects and components are washed periodically with a mild household neutral detergent (ph 5 to 8) to keep the surface in excellent condition.
Restoration through Rubbing
In general, coatings are subject to alterations. It is formulator’s responsibility to assure that such changes occur evenly and that they will not have an effect on the uniform appearance, or the aesthetic impression of the building. Nevertheless, after several years of exposure, coatings might eventually need to be refreshed, even I periodical cleaning has been conducted. This is essential in those parts of the world where climatic conditions put extreme strain on the coating.
Rubbing one effective way for refreshing the coating
1. Prior to rubbing, remove ordinary dirt, oil grease by using a household neutral detergent (ph 5 to 8) diluted with water.
2. Apply the rubbing solution on a lint free cloth or tack and wipe the coating liberally by hand or with a machine. Repeated wiping will enhance the result.
3. Remove the solution with a clean cloth.
Cost Savings with Oven Temperature Profiling
By understanding and controlling thermal cure process, it can improve operating efficiency and maximize the company’s profitability. This article discusses how oven temperature profilers help companies improve the finishing output
Using an oven temperature recorder on a powder coating line
The majority of today’s oven temperature profiling systems is used to simply check that the coated product reaches and maintains the specified temperature for the correct time (dwell time), ensuring the coating is thermally cured. This is an essential step to improving operating profit by simply reducing the risk of rejects or the need for costly rework. Not getting the cure schedule right could significantly increase the true costs to company and affect the whole operation: labor, energy, coatings, and lost business. Guaranteeing cure quality is the mere tip of the iceberg in terms of how profiling can help to achieve the full potential of coating operation
Oven Control: Cost Saving Potential
To be able to control the oven first, understand the way it works.
A temperature profiling system is an ideal tool for maximizing the
efficiency of the process and for getting the most out of cure oven.
Many oven temperature profiling system can be used for such purposes.
For example, systems are available for measuring up to six product or
air temperatures inside an oven, providing protection for up to 2 hours
at 400oF (200oC). This type of system is ideal for standard paint and powder
coating applications. These units have been designed for ease of use and are
rugged, reliable and affordable
Match process conditions: In many coating operations, maximum productivity levels are limited by the rate at which the cure process is performed. Optimizing the oven line speed accurately can significantly affect the throughput of product, and hence its operating profit. After analyzing the oven profile data, it’s possible that optimal line speeds can be determined for each batch of product, ensuring that oven works at maximum capacity for each job, Increasing the line speed by 10 percent doesn’t seem like much, but over the period of a year can have a significant effect on productivity without any significant increase in operating costs because the energy and labor costs would remain unchanged.
Monitor process variations. Monitoring the process regularly allows to identify how oven performs. Using such information is possible to then identify any gradual drifts in process variations, which left unchecked may eventually create cure problems. Such action is made at the company’s convenience so that it can be planned on a weekend or service period without any compromise to the production schedule.
Minimize downtime. When problems occur, identify them immediately. Use the profile data to identify the possible cause of the problem, and allow corrective action. Remember, every minute your oven is non-operational, your operating profit is affected.
Balance the oven, Use an oven profiling system to balance the heating conditions over the entire oven (vertical height or across mesh belt). Place the maximum load in the oven, and optimize throughput. Even today, it’s not uncommon to find powder coating lines operating with the rack only partially loaded. Cure lines with product excluded from the top of the rack to avoid over cure or from the bottom to avoid under cure will benefit significantly from any level of temperature balancing. Often, in convection ovens such imbalance can be corrected by adjusting or servicing air inlet baffles, resulting in a changed airflow through the oven. By using the temperature profiling system, it’s possible to monitor the air temperature over the entire height and length of the oven, which is essential in a temperature balancing operation. Increasing the rack load immediately increases productivity. For example, by increasing the load from eight to ten aluminum extrusions, productivity increases by 20 percent. Successful balancing operations may even allow the set point temperature to be reduced, allowing additional fuel savings.
Energy savings: The financial justification
In a powder coating plant, the operating cost of the cure oven is significant in the total operating cost. Making small percentage changes in the operating efficiency of the cure process can make a significant contribution to the overall operating profitability.
Promote your company’s quality procedures. In a competitive market, providing the product or company’s services with that added extra can make the difference between winning and losing business. With coating functionality and prices being very similar, an excellent means of adding value to the service you offer is to provide validated evidence of the coating cure quality in the form of profile graph. The temperature profiling system was use to determine the maximum temperature and process changes to ensure proper cure of the product. Such information can make all the difference and gives the customers confidence in the product.
Regular use of temperature profiling equipment can not only guarantee the quality of coated products, but also significantly enhance the efficiency and operating profitability of the cure process. Oven profile systems can help you get the best out your oven and maximize your business potential. http://pc112008.ecndigitaledition.com
EQUIPMENT AND TEST METHOD
The impact resistance of a powder coating is an indicator of its ability to withstand sudden physical stress, as hit by a hammer. Rapid indentation of the coated substrate from the coated side is referred to as direct impact. Alternatively, if the rapid indentation is from the uncoated back side, it is reverse impact. Both methods are used to evaluate impact resistance. The thickness and ductile properties of the substrate are significant factors in this test and must be controlled for reliable results. The most common apparatus used to measure impact is the Variable Height Impact Tester, which consists of a cylindrical weight that falls freely within a vertical tube. A table is located below the bottom of the tube to support the test panel. The weight is dropped from various heights, forming indentations of various depths, to determine the impact resistance of the coating. Result is normally reported in inch-pounds. The reported value is the maximum impact that did not crack the coating at a specific film thickness on a specific substrate where evaluated with an aided eye
