Powder Coatings For Commercial Doorsby Mike M. Door Manufacturer and Supplier
Powder coatings have long been acknowledged for outstanding finish quality in appearance, performance, affordability and ease of application in various businesses. Application of powder coatings on industrial doors by commercial doors suppliers has been the subject of interest for the door and window industry for quite a few years. It is true that a few early attempts of putting these coatings into harsh outdoor environments did not see much success but last decade has seen much development in the powder technology. For their exterior durability, powder coatings are now commonly used and specified in particularly harsh environments found in countries like Australia, Malaysia, Hong Kong and South China.
Advances in manufacturing techniques have purported that the common aluminium and silver metallic results favoured in doors, windows and other architectures have been achieved with powder coating. The technology is also supporting textured finishes in powder coating, which are unique to powder. Around the globe, these finishes have been embraced in architecture, specifically for railings, doors, entranceways and walling and partitioning.
The basic feature of powder coating, which has led to its extensive use is the non-existence of solvent content, offering a one-off environmental advantage. Waterborne technologies and high solids liquids coatings are no-doubt improving and have led to the reduction in waste products and emissions, however, both of them are still short in comparison to powder coatings that are almost 100% solids and can cover the surface in a single coat with good finish and performance properties.
Added Advantages of Powder Coatings:
- Powder coatings are awfully tough as compared to its alternatives, particularly liquid paints.
- Powder coatings offer a wide range of colours, gloss variations, finishes and textures.
- The Powder coating’s resistance to chemicals is superior to most other finishes. For instance – powder coatings are alkaline resistant, hence not stained by concrete.
There is no doubt about the fact that powder coating can be used for almost every aluminium extrusion and in many cases, provide a better result at a reasonable cost with fewer effects on the environment. Moreover, powder coatings have many constructive features compared to other coatings.
Powder Coating Process For Commercial Doors:
The basic process includes three steps:
- Powder coating metal pre-treatment process – It is basically a cleaning process, wherein the product must be thoroughly cleaned for dirt, dust, grease, oil, metal oxides and existing coatings. The cleaning process may incorporate the use of a variety of chemical and mechanical methods, depending upon the type and size of the product being treated. Abrasive blasting is an example of preparation method.
- Application of powder – After the pre-treatment step, the product is placed on the powder coating machines. The powder particles melt and join together to form a film like coating. The design and pattern can be selected for creating a unique product. These days, the commercial door suppliers make use of an electrostatic gun for applying powder coating to the metal doors and windows.
- Curing – The powder coatings cure process for aluminium and other metal doors and windows requires a precise temperature for a précised duration to achieve complete cure and to ensure that the full film properties have been achieved. The process and schedule for curing may vary as per the specifications of the manufacturer, level and finish of the dye, etc.
