Applied via vapour deposition in a vacuum chamber, the Parylene Coating Process exhibits superior characteristics and addresses shortcomings of traditional coating processes.
The Parylene coating process involves the CVD method or the Chemical Vapor Deposition method. As a result of the process, parylene is coated on the substrate facades and the molecular level surface. The pin-hole free coatings are conformal, effectually cover crevices, edges, points, sharp ends, internal regions, and there are no gaps at all. The uniformity of the coat is what makes it different from liquid-based coatings like silicone, acrylic, urethane, and more.
The Parylene coating process requires specialized equipment because the deposition happens at the molecular level – typically, the coat grows one molecule at a time.
The process, in short, involves
• The raw material called dimer is heated and vaporized into its gaseous state in a vacuum deposition equipment
• The next process involves pyrolyzing the gas. The dimer is cleaved into its monomeric form.
• Next, in the deposition chamber maintained at room temperature, the monomeric gaseous form gets deposited on the surface as an ultra-thin transparent polymeric film.
The distinct advantage of parylene being deposited in the gaseous form is that the coat penetrates deep into gaps and crevices and successfully covers multi-layered components. The good thing is that the thickness of the polymer coat, which is typically in the microns range, can be changed as per the application and properties desired.
Contact Dawntechsb for a flawless parylene coating process. Dawn Tech is one of the top parylene coating companies in Malaysia.
1. The substrate surface or the material is one of the key variables affecting the process. Parylene can be successfully used on various substrates, including plastic, metals, glass, elastomer, paper, etc. Typically the surface is first treated with A-174 silicone prior to the coating process.
2. The cleanliness of the substrate is another crucial aspect. The presence of oils, particulates, human oils, and other materials can influence parylene adhesive properties.
3. Preparation of the substrate is another key feature that needs to be considered. Parylene is extremely good in covering all areas, crevices, and multiple layers of the substrate until and unless the technicians mask the areas that do not require the coating.
Considering all the three factors above, it is important to ensure that the best coating company is hired to do parylene coating. Dawn Tech offers a high-reliability parylene coating process to diversified industries because we have a highly qualified team of experienced technicians in-house backed by a strong quality management system. Be it any size of the order, volume coating requirements, or small engineering samples; we are here to meet all your requirements with precision.
