Powder Coating and Powders Used

Powder Coating Machine

Powder coating is the mechanical method used for the dry finishing process. It is mostly used in the industrial finishing market on a wide range of products. Powder coatings provide products with high quality, durable finish, and improved efficiencies. These coatings are a perfect way to get protective and decorative finishes as they are available in a limitless range of colors, textures, and technological advancements that result in super excellent performances.

Powder coating gives resistance against wear and tear to the roughest and toughest machinery. It provides a more durable and attractive finish by giving resistance against moisture, chemical, and extreme weather conditions. Also, it reduces the risk of abrasion, corrosion, and many more wear issues.

How does powder coating work?

Powder coatings are mainly based on polymer resin systems which are combined with other additives. They are melt mixed and cooled. A process of electrostatic spray deposition is used for powder coating. In this process, a spray gun is used which applies an electrostatic charge to powder particles that go on the grounded part. After this process, the part goes under a curing oven where with the help of additional heat, the coating results in high density. This is how powder coating is applied. Powder coating can also be applied to the nonmetallic substrate too.

Types of powders used

• EPOXY - Epoxy powders are used for the powder coating process. They have strong adhesion properties. Also, they provide excellent resistance against chemicals and corrosion. Even so, epoxy powders cannot withstand UV exposure, that’s why they have generally used for interior-based applications.
• HYBRID - Hybrid powders are consist of epoxy and polyester resins. Hybrid powders provide excellent mechanical and chemical properties. However, they are not preferred for those applications where weather resistance is critical. Due to better flexibility and smoothness, they are generally used for indoor applications.
• METALLIC - Metallic coating powders have highly attractive visual attributes with excellent strength and durability. They are an ideal choice for thermal coating applications. Metallic coatings have metallic particles added in their composition for aesthetic purposes.
• NYLON - Nylon powders are mostly used for protective coatings. They provide strong resistance against damages caused by impact and abrasion. In many cases, primer is used in the coating to get higher performance.
• POLYESTER - Polyester powders provide strong adhesion properties. They have strong weathering characteristics and lower chemical resistance due to which they are used for decorative items.
• POLYURETHANE - Polyurethane powders are mostly used for decorative and functional exterior applications. They have strong weather ability characteristics and offer excellent anti-corrosion performance.
