Compounds for Electronic Waterproof Materials

The most common waterproof electrical materials in the business are as follows:

  • Epoxy resins are frequently utilized as electronic product potting materials. The material completely encases the PCB. This procedure assures that the electrical gadget is waterproof as well as strong mechanically.
  • Silicone is used as a conformal covering or for potting. It doesn't have the same mechanical strength as epoxy resin, but it's a lot more flexible.
  • Choose urethane if you require a waterproof material with a good combination of mechanical strength and flexibility.
  • The fluorine-containing polymer is a nano-coating with a thickness comparable to p-xylene and a low production cost.
  • Acrylic resin is a good PCB waterproof technique since it dries quickly and is easy to rework. It also has a high level of moisture resistance.
  • Paraxylene can be used to create a very thin moisture-resistant coating. However, because applying paraxylene to PCBs is costly and laborious, it may not be appropriate for all designs.

Suitable Electronics Waterproofing Coating Solution

The nature of the product, your budget, and your requirements all play a role in determining which of our coating options is best for your application. In terms of PCB protection, for example, the PCB may be subjected to high temperatures or chemicals. Acrylic is not a good choice in this scenario since it cannot resist high heat. P-xylene is a superior alternative when complete protection is required at severe temperatures. The negative is that it is extremely costly.

Waterproof materials can assist decrease damage from damp situations, but to cope with all of the other primary difficulties, you'll need a good PCB design program. You must first ensure that your design is reasonable before worrying about how it will react to moisture. Our engineers may perform DRC checks to confirm that the circuit meets industry standards and has all of the features and functions it needs.

Alfa Chemistry can supply a variety of electronics waterproofing nanocoatings, including but not limited to:

Parylene Conformal Coating

Electronic goods in a variety of areas can benefit from parylene's strong and proven protection. It has the ability to penetrate deep into the smallest gaps in some of the most intricate printed circuit board assembly topography, and it acts as a formidable barrier at the microscopic level.

On the package components that make up the PCBA, we employ chemical vapor deposition (CVD) to create a homogeneous and ultra-thin parylene conformal coating that can withstand environmental dangers such rain, salt water, humid air, minerals, and bodily fluids.

The coating has ultra-thin and light weight properties, as well as a uniform coating thickness, a transparent layer, thermal stability, and high chemical resistance.
