Yuan Lei's Little Knowledge | The Difference between Powder Coatings and Waterborne Coatings

Powder coatings and water-based coatings are a kind of coatings, which are widely used in various industries. In order to let everyone know more about the difference between the two, let's take a look at powder coatings and water-based coatings.

powder coating

Powder coating is a solid resin and pigments, fillers and additives composed of solid powder synthetic resin coating.

water-based coatings

A coating that uses water as a solvent or dispersion medium. Water-based coatings do not require a dissolving agent, and are roughly divided into three types of water-soluble coatings, water-diluted coatings, and water-dispersible coatings, and are widely used in the industry.

 

 

 

Difference

The essential difference between powder coatings and water-based coatings is that one is a liquid coating and the other is a solid coating.

Compared with water-based coatings, powder coatings are VOC-free, theoretically 100% utilization, more environmentally friendly.

The thickness of one-time coating of powder coating is generally 60 ~ 80u, and it is difficult for liquid to do so.

Powder coatings are currently mainly coated by charging, so it is difficult to use all substrates. At present, metal substrates are the main substrates. Liquid does not have this restriction.

Powder coatings are difficult to achieve some surface effects of liquid coatings. For example, the mirror effect, even the best powder coating is difficult to avoid defects such as orange peel. Therefore, it is difficult for powder coatings to completely replace liquid coatings.

6. Coating resin system: the resin system of both water-based coatings and powder coatings is quite similar. Popular indoor and outdoor systems are available. The text is all: polyester, epoxy, acrylic and other water-based coatings and powder coatings. Therefore, the use of both occasions, the application industry also has a common, but not completely universal.

7. Water-based coatings can be made with strong metal feeling and bright enough metal effect. The problem that the limited metal particles of powder coating are arranged inside the powder coating, at present, the bonding metal powder can only partially replace the paint or achieve the effect of water-based metal paint. But on the whole, the application of bonding metal powder is still very wide. Water-based coatings and powder coatings on the surface effect of the difference, mainly in the metal effect, plain color effect, almost the same.

Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.
