Bonding mixer refers to a bonding mixer. The main difference between the so-called bonding mixer and the ordinary mixer is that the bonding mixer has special processing steps for heating, softening, and bonding during the mixing process. This characteristic makes it more suitable for the mixed production of powder coatings with metal pigments, i.e. metal powder. The metal powder coating processed by the bonding mixer has many advantages, such as high glossiness, good leveling, good metal realistic effect, saving metal pigments, and recyclable floor powder
