USE OF POWDER COATING IN FURNITURE
Powder coating is a dry painting processor method, which helps in providing customized finishes to metal furniture. It allows us to choose from a range of colors and textures for every piece they produce, without compromising its features or characteristics. It enhances any metal product with a high finishing. The method of powder coating involves the use of dry, free-flowing, and electrostatically charged resin, which is used for the furniture in even coats, then they are cured in a high-temperature so that it can stay for long period of time and improver the life of the furniture.
It starts with cleaning furniture to remove any dirt or grease. The piece is then carefully pre-heated to a specific temperature to assist the powder in adhering to the surface. Next, the powder finish is sprayed onto the furniture using an electrostatic gun. The powder helps in giving the uniform coating. Then, it is cured in a specially designed oven, which helps the powder to gain the shape and become hard, which help in getting the attractive finishing. Compared to other finishing methods, powder coating offers a host of benefits.
Liquid paint is less durable, and more resistant to scratches and chipping, while electroplating is often expensive, and may not be suitable for all furniture types. Powder coating, on the other hand, delivers a uniform, clean coverage, with reduced emissions, and minimal material waste. Compared to other finishing methods like painting or varnishing, powder coating offers phenomenal longevity. Plus, the extra tough finish means your furniture items will be less likely to corrode. The powder coating process requires fewer materials than other finishing options. With the right tools, powder coating professionals can minimize overspray and waste.
Plus, because most of the process is automated, there are fewer labor costs too. What’s more, because powder coated finishes have a much longer lifespan, there are fewer maintenance and repair costs to consider too. Manufacturers may even be able to charge more for their finished products, thanks to their exceptional lifespan. Excellent durability, UV stability, hardness, abrasion resistance and corrosion resistance combined with higher film thicknesses of powder coatings make them ideal for outdoor furniture and equipment which see rough use outdoors. School furniture such as tables and chairs are easy to powder coat.
Doorknobs can be powder coated inside or outside. But also powder coatings for kitchens and bathrooms are very suitable and decorative. Having high film weight, they give good abrasion and chemical resistance, and humidity protection.
RISE IN DEMAND FOR POWDER COATING FOR THE AUTOMOTIVE
Powder coating is used in automobile parts or components It is not applied to door and body panels, but it is making inroads in this area. In addition to their excellent durability and corrosion protection, powder coatings are attractive because they are free of volatile organic compounds (VOCs) and it is possible to recover and reuse nearly all over-sprayed material. Powder coatings are used in automotive applications because it helps in corrosion resistance. Powder coatings are also formulated for use in many applications with different colour and finish requirements, including metallic effects and high- and low-gloss color, and clear finishes.
Many different colours can be applied, creating unique special effects in a single coating layer. Shorter cure time often reduces energy consumption and eliminates VOC emissions, which is more sustainable and operator friendly. In addition, many powder coatings are single layer and offer improved productivity over liquids that are used in multilayer coating systems. Up to 95% of the overspray in a powder coating booth can be collected for reuse. Powder coatings are applied via an electrostatic charge and then cured with heat (typically 160-200 °C). Unlike liquid coatings, as powder is applied, it does not get saturated or overdiluted.
This yields a smooth surface finish on the part. Polyester, epoxy, urethane, acrylic, and hybrid powder coatings are employed based on the substrate and the specific needs of a given application—abrasion resistance, high-temperature insulation, or corrosion resistance. For instance, polyester powder coatings are available in super-durable formulations that have applications where there is extended exposure to harsh conditions. Additives are used to further boost anti-scratch performance, and stone-chip and chemical resistance.
The global powder coating market is poised for robust growth, driven by increasing demand for environmentally friendly coatings and advancements in application technologies.
