Outdoor aluminum signs provide a professional presentation to any storefront or business. Aluminum signs designed with high-performance vinyl can last many years, saving you money over time. Lightweight and durable, aluminum signs easily can be paired with a metal hanging bracket attached to a post.
Powder coating is a type of coating that is applied as a free-flowing, dry powder.
The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer.
It is usually used to create a hard finish that is tougher than conventional paint.
Powder coating is mainly used for coating of metals, such as household appliances, aluminum extrusions, drum hardware, and automobile and bicycle parts.
Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.
Advantages of powder coating instead of other coatings
Powder coatings contain no solvents and release little or no amount of Volatile Organic Compounds (VOC) into the atmosphere. Thus, there is no longer a need for finishers to buy costly pollution control equipment. Companies can comply more easily and economically with the regulations of theU.S. Environmental Protection Agency.
Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
● Applied film thickness of up to 80 microns.
● Excellent weather resistance
● Excellent colour stability and consistency between batches
● Good edge coverage
● All powders are class 1 or class 2 approved
● Wide colour range
Powder coating is widely considered to be the ideal method of decorating and protecting aluminum components, products, and parts. By spraying and fusing this mixture of pigments and resins onto a surface, you can achieve a high-quality, extremely durable finish that will extend the life of your metal and ensure its continued aesthetic appeal.
The main difference between choosing a powder coating method and traditional liquid paint application is that liquid paint requires a solvent in order to preserve the binder and filler parts in a liquid form. By applying the powdered coating and then curing it with heat, the end result is actually harder and tougher than conventional paint.
With powder coating, there are zero or near-zero volatile organic compounds (VOCs), which can be harmful to humans and the environment alike. The reduced hazardous waste created by powder coating compared to liquid paints also make clean-up easier and allows the coated material to be easily recycled later on.
As far as appearance goes, powder coated aluminum is much more consistent and even than conventional painting methods. Plus, because powder coating can produce a much thicker coat with fewer visible differences (like running or sagging paint), it can be significantly more durable than traditional liquid paint. The flexibility in choices of powdered resins and pigments allow for virtually every color combination - even glosses, metallic finishes, and a variety of different textures.
