Parylene F Powder is a good alternative solution for heavy liquid coatings and potting materials. It is very thin, lightweight and has good moisture, chemical and dielectric barrier properties. In addition, Parylene provides unparalleled stability in high temperature and ultraviolet environments, providing maximum protection for LED applications.
Parylene is the name of a polymer series, an organic coating material. They have polycrystalline and linear properties, have good dielectric properties and barrier properties per unit thickness, and are chemically inert. Parylene is a molecular-grade polymer with an ultra-thin coating, optical transparency, and good compliance, regardless of the size or complexity of the surrounding components.
Parylene is applied by vapor deposition, eliminating the need for spot, spray, brush or dip processes. The coated part is placed in a deposition chamber, and a powder material called "dimer" is placed in an evaporator, which is located at the other end of the deposition system. The dimer is heated to sublimate it into steam and then heated to decompose it into steam with a single molecular structure. This steam is transferred to a room-temperature gas cell, where the dimer spontaneously polymerizes on the quilt to form a thin parylene film. The coating parylene process is performed in a closed vacuum-controlled system, and the deposition chamber is kept at room temperature during the deposition process. There are no solvents, catalysts and plasticizers in the coating process.
Because there is no liquid body during the deposition process, the meniscus, silting or bridging of liquid coating applications is not seen. The "growth" of Parylene coating molecules not only forms a uniform conformal coating layer with a specific thickness, but also penetrates into every gap, because the film is formed from gas, and has nothing to do with the inaccessibility of the coated part. Completely encapsulated substrate.
In addition to excellent protection, Parylene Coating also has good biocompatibility, biological stability, excellent self-lubricity, uniform controllability of the coating, and good physical and mechanical properties. Over the years, it has been widely used in aerospace, microelectronics, semiconductors, sensors, magnetic materials, medical equipment, cultural relics protection and other fields, and has slowly penetrated into people's daily life.
Parylene is a common name for a series of unique polymers. The basic member of this family is called Parylene, or parylene, which is a completely linear, highly crystalline material. Parylene is a protective polymer material. It uses vacuum vapor deposition process to form a protective film. This film has the characteristics of uniform thickness, dense no pinholes, transparent and no stress, etc., and has excellent electrical insulation and protection.
