A coating stick is a laboratory tool used to evenly coat liquid materials on a variety of material surfaces, such as coatings, inks, glues, adhesives, etc. Their design and construction can affect the thickness, uniformity and quality of the coating and therefore play a key role in the coating process. Coating rods are usually made of stainless steel, plastic and other materials with different groove shapes and sizes to meet different coating needs.

Coating rod type
There are various types of coating rods, which can be selected according to the purpose and requirements of coating. For example, a wire-wound coating rod has a filament winding line to control the distribution of the coating material during the coating process; The extrusion coating rod is formed into a groove by extrusion to realize coating. In the manufacturing process, the coating rod adopts an integrated molding process, and different groove shapes can be customized to achieve precise coating effects of different fluids.

Coating rod has been widely used in the fields of laboratory preparation of coating film, sample preparation, coating research and so on. By selecting the right coating rod, researchers can explore the properties of different coating techniques, coating materials, and precisely control the thickness and uniformity of the coating during the experiment.

Application field
Coating rods are widely used in different types of coating processes such as coatings, inks, glues, adhesives, etc., covering many fields, such as paper printing, packaging, electronics, pharmaceuticals, cosmetics, etc.

Material and groove design: The material and groove design of the coating rod are crucial to the coating effect. Different materials and groove shapes can produce different coating effects, affecting the uniformity, quality and thickness of the coating.

Coating thickness control: The coating rod can be used to control the thickness of the coating during the preparation of the coating in the laboratory. By adjusting the pressure of the coating rod, the coating speed and the fluidity of the coating material, different thickness coating layers can be achieved.

Experimental design and research: In the coating research, the coating rod can be used as an important experimental tool. Researchers can explore the parameters of the coating process and optimize the coating technology by testing the coating effect under different coating rods and different coating conditions.
