What are the advantages and disadvantages of painting and powder coating on the surface of thermos cup?

Hello everyone, "Dong Dong Talk Cup" is here. I remember that the last time I shared the surface spraying process of thermos cups was more than a year ago. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlRecently, some customers were confused about whether to spray paint or powder coat the product, so today I will share with you the advantages and disadvantages of spraying paint and powder coat on the surface of thermos cups.

When choosing or manufacturing a stainless steel thermos, surface treatment is a crucial step, which not only affects the appearance of the product, but also involves durability and other functional factors. Painting and powder coating are two common surface treatment technologies. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlAlthough their purposes are similar, that is, to improve the appearance and protective performance of the product, they differ in application process, effect, function, advantages and disadvantages.

Process Differences

Spray painting is a liquid coating process that involves spraying liquid paint evenly on the surface of the thermos cup through a spray gun. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlThis process may require multiple coating and drying to ensure that the paint layer is even and dry.

Powder spraying, also known as powder coating, is the process of spraying powdered paint onto the surface of the thermos cup by static electricity or pressure, and then baking it at high temperature to melt the powder into a thin film. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlThis technology does not involve solvents, so it is also seen as a more environmentally friendly coating method.

Effects and functions

The surface of the thermos bottle after spray painting is usually smooth and colorful, and can achieve high gloss or matte effects. Liquid paint can easily create a variety of visual effects, such as metallic texture, pearlescent effect, etc. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlHowever, spray painting may not perform well in terms of scratch resistance and corrosion resistance.

The surface after powder coating is usually thicker and harder, with better wear resistance and impact resistance. Since the powder coating layer is usually thicker, it performs better in resisting external physical damage. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlThe color selection may not be as diverse as spray painting, but the consistency and coverage of powder coating are stronger.

Advantages and disadvantages

Advantages and disadvantages of spray painting:

Advantages: Various appearance effects and wide range of color choices. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlHigh gloss or special texture can be achieved.

Disadvantages: Greater environmental impact, contains volatile organic compounds (VOCs). Relatively low durability, easy to scratch or peel.

Advantages and disadvantages of powder spraying

Advantages: Environmentally friendly, does not contain VOCs. Strong durability, good abrasion and impact resistance.

Disadvantages: Relatively limited choice of colors and effects. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlHigh initial investment cost and equipment cost.

For example, my customer likes the visual effect of spray painting, but is worried that the surface coating of the painted thermos will easily fall off after sale, thus affecting your brand reputation and sales situation. http://www.zhanyict.com/en/ProductsDetail-VB-10384.htmlIn the next article, I will tell you how to improve the adhesion of the thermos surface after spray painting.
