Powder coatings are often a one stratify finish, unromantic to suitably cleaned and pre-treated substrates. Some coatings such as metallics, require a well-spoken stratify to protect the metallic effect, although these are often stuff replaced with the Dulux Precious® and Electro™ PowderStratifyRanges which do not require a well-spoken coat. Can powder coatings be unromantic on site? Powder coatings are a factory unromantic finish using specialised equipment. The equipment includes an electrostatic spray gun, spray diner and an oven to torch (or cure) the coating. On site using is not possible given the hot curing trundling required to fuse the coating. Can powder coatings be unromantic straight onto metals substrates? Whilst powder coatings often require no primers, it is important to provide a wipe and pre-treated surface for the powder stratify to pinion to. Metals that are planned for internal location can escape the need for pre-treatment; however it is prudent to provide some metal pre-treatment such as a phosphate finish to steel or chromate finish to aluminium to ensure maximum performance of the finish. Is it true that powder coatings can withstand any conditions and can plane be unromantic to rusty metal? Unfortunately there is a myth that since powder coating is easier to wield than wet paints and retains a very nonflexible finish, that powder coatings can withstand anything and everything. Indeed this carefree view has led to some disappointing applications of powder coatings. Powder coatings rely on a clean, pre-treated surface like any and every other coating.   Rusty metal deposits must be removed prior to powder coating, as over coating with powder will only mask what is fundamentally corroding metal. Powder coatings are terrific in resisting knocks and abrasions, chemicals and the effects of sun. However, if not cared for, the coating can show up scratches and mucosa integrity loss. Are powder coatings suitable for use on surfaces which come into contact with food? Some powder coatings are designed specifically for contact with supplies but this is a specialised application. If this full-length is required, you should contact Dulux for remoter information as the standard ranges of powder coatings are not suitable for contact with food. Do powder coatings provide an electrical insulation characteristic? Some powder coatings are specifically designed for electrical properties, but again, as with supplies grade coatings, this is specialised and you should contact Dulux for remoter advice. I know that mobile phones should be turned off in areas where there is paints, solvents & petrol but are there any dangers with mobile phones been virtually powder spray booths? Whilst powder coatings have the wholesomeness over solvent based coatings of having a lower explosion point and therefore less flammable, circumspection should unchangingly be exercised with any electrical source such as mobile phones. Powder coatings are a fine organic pebbles which in upper concentration, in the presence of air and an ignition source such as a mobile phone, could trigger a pebbles explosion.   The concentration of pebbles required to facilitate a pebbles explosion is significant, however, it is prudent to alimony unnecessary equipment yonder from the diner and powder. As a precaution, Dulux recommends that mobile phones should be kept well-spoken of these areas. Manufacture How are powder coatings manufactured? Powder coatings are produced by dry blending resins, pigments, additives and curing teachers which are then extruded at elevated temperatures to melt and mix the ingredients. The material then becomes thick and viscous like a honey mixture which is cooled using super chilled water, surpassing the material is crushed progressively to a fine, well specified particle size. Specialised equipment including rotary sieves and particle size measuring equipment is used to monitor and tenancy the particle size distribution. Where are Dulux Powder Coating's manufactured? Dulux has two production facilities for powder coatings supplied to the local market. Our facility in Dandenong South, Victoria has four production lines with the sufficiency of handling small batch sizes. The second facility is located in Auckland, New Zealand, which moreover has a variety of small and large equipment to cater for the wide-stretching range of products manufactured by Dulux. Colour What considerations should I make when choosing a colour? Are there good and bad colour selections? Not all colours behave the same during using or performance on site. Generally, light colours are platonic for increasingly applications than other colour groups.   Light colours swizzle little light considering the white pigments help reflect the light. This reduces the heat up effect on parts.Visionlesscolours swizzle light and hence heat far increasingly readily, which explains why visionless cars are hotter than white cars in the sun. If heat is an important element in the diamond or use of your product, the effects of light and visionless colours are an important consideration.   Bright colours behave differently then as they not only swizzle light and remit this as brightness, the pigments are increasingly readily damaged by ultra violet light reducing the life of the colour. Bright colours that include reds, oranges, greens and blues are recommended for applications where colour retention is not hair-trigger such as playground equipment and furniture. What is your stock colour range?   Dulux Powder & Industrial Coatings offers a range of over 300 stock colours in either matt, satin or gloss finish. Our standard colour range includes colours to match the popular prepainted steel colours from the Colorsteel ands Colourcote collections and a myriad of fashionable solid and metallic colours. To view our standard colour range click here.     Can I match a powder coating to a paint colour? Unlike paints which can be tinted to thousands or shades and finishes, powder coatings are formulated and factory produced. Powder coatings cannot be tinted successfully since the solid particles of each colour do not tousle together, causing a mottled, speckled squint when two variegated colours are mixed together. If you want to match a Dulux paint colour, we recommend you contact our Customer Service Team. Why do some paint and powder coatings share the same name but are entirely variegated colours? Paints and powder coatings have evolved from variegated industries; house paints from decorative applications and powder coatings from industrial uses. While Dulux has endeavoured to uncurl colour names wideness industries, there are examples of colours e.g. Magnolia, which exist in both paints and powder coatings.   It is recommended when choosing a colour that a colour sample of each product be reviewed to ensure the colours chosen meet your needs. What is the weightier way to coordinate colours between powder coatings and paints? Dulux can produce special colours and finishes on a Made to Order basis. Due to the nature of the manufacturing process, minimum quantity conditions limit the possibility of non-standard colours to typically large or ongoing projects. It is recommended when choosing colour, the powder coating colour be chosen first, as scrutinizingly every powder stratify finish can then be matched in a Dulux paint system. Can you provide me with an excel document of the colour names and RGB values? Please finger self-ruling to download our colour names and RGB values here. Standards Is there an Australian or international standard for the correct tideway to powder coating? There are various standards for powder application, tent the correct procedure for pre-treatment, powder application, testing and performance. The standards often relate to the nature of the substrate. Please refer to our How to Specify page for remoter information. Is there a standard for the unscratched using of powder coatings? Australian Standard AS3754 –Unscratchedusing by electrostatic spray outlines the procedures for unscratched using of powder coatings. Copies of this standard can be obtained from your local Standards Australia office. What precautions should we take when handling powder coating? Dulux recommends reference to the Australian Standard AS3754 –Unscratchedusing by electrostatic spray for correct handling of powder coatings. In unstipulated use of a pebbles mask, protective suit and/or windbreak creams are recommended. What is the most worldwide international performance standard for powder coatings? There are various standards for powder coating depending on if the speciality of the standard focuses on unscratched application, metal finishing and end use using e.g. coatings for children’s toys or quality test standards. The standards often relate to the nature of the substrate. What is the recommended standard for powder coating of aluminium? For aluminium substrates, Australian Standard AS3715 – Metal Finishing – Thermoset Powder Coating for architectural applications is recommended and most wontedly referred to in Australia.   There are other standards which offer similar conditions, criteria and performance features such as British Standard BS6496 which is increasingly wontedly referred to in Asia and abroad. What is the recommended standard for powder coating of steel and galvanising? For unstipulated metals including steel and galvanising, the Australian Standard AS4506-2005 for Metal Finishing – Thermoset powder coatings is recommended.   The British Standard BS6497 has been referred to quite considerably in the past as this deals directly with the powder coating of galvanised metal substrates. What is a worldwide standard for tautness performance? The most recognised standard of tautness of coatings is the AAMA standards. The AAMA standards are based on performance criteria set out by the Architectural Aluminium Manufacture’s Association, from where the reference to AAMA originates. The three AAMA standards used to specify powder coatings are below; 3 years Florida resistance (AAMA 2603-05) 5 years Florida resistance (AAMA 2604-10) 10 years Florida performance (AAMA 2605-11) See How to Specify page to find out increasingly information regarding specifying the correct AAMA Standard. What are some standards which outline some worldwide performance test and quality warranty test standards? There are many standards established simply to outline an well-set standard for measuring a coating’s performance. Examples of worldwide tests might be gloss measurement, adhesion of coatings, weathering performance, hardness, chemical resistance or stain resistance. Among the many standards are the Australian Standard AS1580 – Paints and related materials – Methods of Test and British Standard BS3900. How can I get a reprinting of the standards? Copies of standards can be purchased from your local Standards Australia office in major wanted cities or by accessing one SAI Global here. Environment How long does powder coating stock last for when kept in the carton? Powder coating storage lives vary equal to the technology and the storage conditions.OftenDulux recommend 2 years surpassing the powder is re-tested to personize no ousting in mucosa properties. If the powder has wilt lumpy and undivided moisture, the material may be sieved and then fluidised for 10 minutes to condition the powder in preparation for application.   If the powder has wilt too lumpy and solid, it would suggest some pre-reaction of the powder which cannot be reversed nor corrected. Some technologies may have shorter storage periods, but these are often outlined in the technical data sheets and/or product packaging. I have heard well-nigh the practice of sultry the waste powder inside the box and making the powder go hard. Is it towardly to heat the waste powder in a box ready for disposal? This practice has been used quite often in the industry and the rationale for reducing powder pebbles is admirable. However, placing wafer-thin cartons inside ovens produces the risk of a fire which can have devastating results. There have been examples of fires at powder coating facilities in Australian where operators placed waste powder cartons in the oven which caused a fire.   Aside from the loss of production and equipment from the fire, not to mention the safety risk to staff, most insurance companies will not imbricate such incidents. Are powder coatings classified as dangerous goods? Powder coating are not classified as dangerous goods. There are no solvents in powder coatings which simplifies the transport and storage of powder coatings. Are powder coatings considered environmentally friendly? Everything relative, powder coatings are considered far increasingly environmentally friendly that wet paints or anodising. Powder coatings use no solvents which are harmful to the environment. Over sprayed powder can be recovered, sieved and then reapplied to other products which helps reduce waste powder.   Whilst some Municipal Councils restrict the waste disposal sites for powder coatings, the products have limited to no leaching effect in dry form and no leaching effect in the cured form. Given the very good tautness of powder coatings, the need to recoat the sits is less common, meaning fewer burdens on the environment in the future. What is the process for cleaning up spilt powder coatings? Powder coatings can be safely cleaned up via a skim and spade or a vacuum cleaner, provided the value of powder is not excessive. For large spills, the powder should be shovelled into a plastic bag inside a carton and tipped into the box for easy disposal. What is the correct procedure for disposal of powder coatings? The rules and regulations for powder waste disposal vary wideness states and regional councils. In many instances, powder coating is suitable for land fill; however it is important to contact your local steering and/or Environmental Protection Agency office to sieve local requirements for waste disposal.   As a rule, ensuring waste powder is placed in securely sealed packs with no leaks is important to limit nuisance dust. This will ensure that powder is not emitted to the undercurrent when loaded to the waste truck on your premises and hence stave subsequent complaints from neighbours. Care & Maintenance How do I maintain and refurbish a powder coated surface? The effects of pollution, dirt, grime and salt deposits can all yaffle on a powder coated surface over time. To proffer the constructive life of powder coatings and fulfil any warranty requirements that may exist, a simple regular maintenance program should be implemented for the removal of residues. As a unstipulated rule, all powder coated surfaces should be cleaned every six months.   However in areas where pollutants are increasingly prevalent, expressly in coastal or industrial regions, a cleaning program should be carried out on a increasingly frequent basis. To wipe a powder coated surface, customers should thoughtfully remove any loose deposits with a wet sponge and then use a soft non-abrasive skim or reticulum in combination with a summery household detergent solution to remove dust, salt and other residues. Finally rinse all powder coated surfaces with wipe water.   See our Care & Maintenance page for remoter information. How long do powder coatings last? From the perspective of adhesion and mucosa integrity, correctly unromantic and pre-treated powder coated metal can and has lasted since it was first unromantic increasingly than 40 years ago. Powder coatings are considered extremely resilient and have been a coating of nomination for use on gas and oil pipelines which are veiled in earth or underwater. Powder coatings have moreover been used on automotive and appliances given their spanking-new tweedle resistance, hardness and chemical resistance.   From the perspective of resistance to light and UV degradation, some powder coatings are outstanding, stuff used on major buildings such as our Duratec®  and Fluoroset® ranges. The standard and most worldwide powder coatings are designed for unstipulated use and applications. Standard powder coatings offer good weathering resistance, spanking-new mucosa integrity and hardness.
