A coating material developed by the coating of Parylene material in recent decades has been widely used in many fine industries. Just entering the market has been widely welcomed.
The parylene-based organic coating is prepared by vapor-deposition polymerization of the active monomer. The vapor deposition of the monomer and the formation of the coating are performed simultaneously without an intermediate liquid transition state. This gives the following advantages. Parylene Powder Supplier to share with you:
1. Parylene materials are generally formed by vapor deposition. Compared to the conventional solution-forming coating method, parylene does not use any solvent or additives during polymerization, thereby avoiding air leakage and surface stress.
2. Parylene-based organic coatings can be polymerized at room temperature to form a coating compared to conventional solutions.
3. Vapor deposition allows the Parylene Material coating to penetrate and coat the hard-to-reach surface of the liquid coating and does not form a bridge between adjacent surfaces.
4. Parylene Material organic coating is formed by the coagulation of active monomers on the surface of the polymer into a high polymer. Compared with the traditional solution forming coating, the molecules are closely connected, which makes it have unparalleled consistency and uniformity. And there are no pinholes and defects.
5. The production process of the parylene organic coating is completed instantaneously, and no condensation time is required during coating so that there is no condensation crystal residue on the surface of the coating, so the coating is purer and chemically inert than the conventional coating. To make the coating more stable.
6. The parylene-based organic coating is grown on the surface of the substrate, and the polymer can be controlled at 100 angstroms to several hundred micrometers. This property is the same as the para-xylene organic coating. Together with the low permeability properties, it can be made to obtain the most needed protection with a minimum amount of coating.
7. Useful properties of Parylene Coating include dry coating lubricity, particle stability, hydrophobicity, biocompatibility, chemical insolubility, no by-products in the formation process, unclear sensibility to hydrolysis and erosion, thermal stability, low permeability, and high insulation. This coating can be removed by several methods to facilitate repair of the covered substrate, such as expensive circuitry, and the repaired circuit can be recoated with a parylene-based organic coating.
At present, there are many applications of Parylene C (PC) Parylene D (PD) Parylene N (PN), etc., and the main coatings used to produce coatings are their monomer C powder, D powder, N powder.
