Electrostatic Spraying - Helps to slow the spread of contagious illnesses. Used in Hospitals, Offices, Gyms, Museums, Retail Outlets, Airports, Public Transport, Cinema's and the list goes on.... What makes Electrostatic Spraying different from other types of sprayers? With conventional sprayers, the only surfaces that will be coated are those that are in the line of sight of the spray nozzle. Electrostatically applied liquids have a wrapping effect, so that complex objects and areas hidden from the line of site get coated with the liquid. #StaySafe #ElectrostaticSpraying #GlowCleaning #Pathogens https://www.instagram.com/p/CFUz-RXjSGz/?igshid=x57vb1p4fuyh

Aluminium Powder Coating - Diamond Custom Coatings, Inc.

Generally powder coating may be regarded as an environmentally favoured method of applying a finish particularly as it avoids the use of solvent-based paints avoids overspray wastage, and any unused powder may be fully recycled and used again.

Although powder coating was conceived as a method of finishing metal, technology has evolved so that it is now a common choice for ceramics, plastics and even wood.

Research shows that powder coating is the fastest growing coating medium and with the environmental advantages coupled with its excellent finishing properties, it is a trend that is likely to continue.

The 3 steps in the aluminium window restoration process are:

1. Preparation. Preparation is what takes the greatest amount of time and there is the temptation from tradesmen inexperienced in two pac spray painting application and the DIY home renovator to take short cuts. Often the short cuts are a result of lack of knowledge rather than being lazy. However the end result of not carrying out the correct amount of preparation is a less durable poor quality finish.

2 .Paint application For two pac paint application, it's important that the substrate is free from any dirt, grease or grime build up. The outside of your windows frames can be cleaned using a non-salt based soapy water and a sponge. To be carefully rinsed with fresh water or water pressure cleaner. But, this can't be done on the inside so you can use a solvent wash such as prepsol. A solvent wash can be used on both sides. Use a commercial grade scour pad to apply the solvent. Before you wash down the inner frames, it is best to vacuum the inside tracks first to remove any dust or bug build up.

The wipe on wipe process of cleaning is important. Apply the solvent with a clean cloth in small sections because it evaporates quickly. The problem though is that the residue containing dirt and grime will remain unless you quickly wipe it off using another dry, clean cloth.

Keying up the surface by sanding is probably the most tedious part but very important. Use 120grit for chalky powder coated surfaces, 240 grit for non chalky powder coated surfaces, and 60 grit for anodized surfaces. It is imperative that the anodized surfaces are aggressively attacked and keyed up properly. Using 80 grit and lighter on anodized surfaces is a waste of sand paper and your time.

Mask and protect of all rubbers that hold the glass in place. Protecting the glass itself and all surrounding finished surfaces from overspray during paint application is critical. Skip on this process and you will have an expensive cleanup bill.

A three coat two pac paint application is recommended by the major paint manufacturers. The first coat is a light primer coat (single pac etch primer is recommended) which should be left to dry for at least 30 minutes more or less depending on the temperature and humidity. When dry, apply two medium to thick top coats. However, it is recommended to apply four light coats consecutively, having time intervals between coats for tack off to occur. This allows solvents to evaporate and the paint starts to go tacky to the touch.

3. Mechanical overhauling. Once painted and all masking is removed, the mechanical overhaul can begin. This includes replacement of all window and sliding door rollers, installation of new weather felts to stop window rattle at the openings, and checking of window latch springs and installation of new springs so that latches can be centred. Complete replacement is done when no replacement springs are available. Sliding door handles can also be replaced.

Commonly electrostatic gun or corona gun is used for applying the powder coating to metal objects. Here, lets discuss the working of electrostatic gun. Negative electric charge is imparted to the powder. The negatively charged powder is then sprayed towards the grounded object by mechanical or compressed air spraying equipment. It is then accelerated towards the workpiece by the powerful electrostatic charge. The object is then heated, and the powder melts into a uniform film, and is then cooled to form a hard coating. To achieve more uniform finish preheating could help but problems can also be created as runs caused by excess powder.
