Introduction To Powder Coating Powder coating is one of the most advanced coating processes around and provides the ultimate finish durability and longevity. Since the powder coating process involves no solvents it is environmentally friendly since no harmful VOC (Volatile Organic Compound) emissions are released into the atmosphere when applied. Through an advanced reclamation system there is also virtually no waste since 99.9% of the over sprayed powder is recycled. What this means to you is that it will last longer and stand up better to the tasks of every day use and at the same time does not harm the environment. The powder coating process involves electro statically charged finely ground up dry plastic resin & pigments that are sprayed onto a electrically grounded object. The substrate is then heated in an oven and cured at over 390°F/190°C ( Metal surface temperature ) for several minutes while the powder is baked on. The product is then cooled down and is ready to use requiring no drying time unlike the wet painting process. The final powder coated product looks better, stands up better to the elements and lasts longer than a product painted with the conventional wet liquid paint application. . The finished coating is more durable and has a better looking finish at the same time being better able to withstand the harshness of the outdoor environment compared to the enamel and epoxy wet spray paints that are normally used. Bins-n-Benches powder coating finish is available in many custom colours POWDER COATING ADVANTAGES Economic Advantages • Up to 99 percent of over sprayed powder can be reclaimed. Captured powder is typically sieved and returned to the feed system, mixed with virgin powder and reused. The high reclaim efficiencies of Nordson powder coating booths typically allow powder coaters to achieve overall powder coating system efficiency in excess of 95 percent. • Very high material utilization rates minimize waste and associated disposal costs. • Clean-up and waste disposal costs are minimal, since practically all powder coating materials contain no VOC’s and are not considered hazardous waste. • Eliminates use of solvents and the need to maintain viscosity balance and flash-off time requirements. • Allows users to achieve a broad range of coating thick nesses (typically ranging from one to eight mils) in one pass without runs or sags. • Minimizes rejects since damaged coatings can be blown off before heat is applied to the parts. • Eliminates the need for fresh air make-up and reduces air conditioning costs since all air is typically returned to the plant. Ease of Application • One-coat coverage often reduces production time and related costs. • Wraparound effect achieves full, two-side coverage of some products after spraying only one side. • Coating process is easily controlled and automated. • Powder coatings require no pre-mixing, viscosity adjustments or stirring. Finish Quality • Several available powder materials provide coating uniformity and consistent edge coverage, and deliver a wide range of coating thick nesses for superior corrosion resistance. • Numerous powder formulations meet the broadest spectrum of requirements for final finish color, gloss, hardness, weathering, abrasion and chemical resistance. SAFETY: The total lack of solvents eliminates any problem of danger, both during application and stocking, including those of explosion or fire. ECOLOGY: All risks to human health and pollution to the environment are reduced. All our products meet the international requirements in regard to safety for the environment and human health. Our customer service centre gives all the necessary information about precautions to be adopted using the various products. EASINESS: The thermo-setting powder paints need neither particular preparation, setting-up or control before application, nor specialised labour. ECONOMY: Dry residue equal to 100% guarantees a very high hiding power and also an almost total recuperation. The exchange of air in the polymerisation oven is reduced to the minimum. QUALITY: One single coat ensures a coverage with a thickness from 40 up to 100-120 microns, with excellent resistance against the atmospheric ,chemicals, mechanical and corrosive agents, in general , also for external uses. The colour range is virtually unlimited, in any sort of finish; glossy, semi-glossy, mat or with special effects, with first -class reproduction results. What is Powder Coating? Powder Coating is a dry finishing process that uses finely ground powders of pigment and resin to coat the surface. Powder coating uses an electro statically charged technique in which the powders are charged so that the powder particles adhere to the metal surface and are then melted and fused together in the curing process. What are the benefits of powder coating versus wet painting? • Superior Scratch Resistance • Superior Chemical Resistance • Superior Impact Resistance Why change to Powder Coating? • Greater durability of Powder Coating • Cost competitive to internal wet coating expenses • Eliminates environmental issues for all • Custom colors available • Textured finishes available • Indoor, Outdoor, Harsh environmental powders are available • Excellent silkscreen results over powder • Touch up with powder or paint
