Potting is the act of filling a circuit board with an insulation liquid. The liquid hardens to protect circuit boards from shock and other environmental factors. Because electronic assemblies are frequently exposed to extreme temperatures and shock, this is crucial. Circuit board protection potting can be used to protect your circuit board components from extreme environmental conditions like temperature swings. It provides long-term protection.
Epoxy resin
PCB potting is an essential part of PCB protection. It is capable of providing reliable protection for operation in harsh environments. Epoxy resin is superior to other materials in terms of chemical, vibration, and corrosion resistance. Plasma Ruggedized Solutions’ two-part electronic potting compound, Kryptos-17 ™, fulfills these requirements. It is extremely wet and cureable. It provides greater circuit board protection and a longer life span.
Most circuit board potting is made of epoxy or urethane. Epoxy and urethane are both heat-resistant, so they won’t cause any damage to the components. Both materials have excellent adhesion and dielectric barrier. Both epoxy and urethane have their drawbacks. It can be very difficult to work with. Potting compounds can be difficult to get rid of, in addition to their physical limitations.
Urethane
A process called urethane circuit board protection, potting provides a protective layer for a PCB assembly. It protects electronic components from heat and increases structural strength. The final step is to place the PCB assembly in an open box. The components and PCB are then placed in an appropriate open box. The potting compound is dried to create an encasement which becomes part of the final product.
PCB potting works in a similar way to conformal coating. This process makes use of organic polymers to provide thermal, chemical and electrical insulation. This protects PCB components against physical shock and other dangerous elements. It improves the electrical performance. Visit our website to learn more about potting.

Silicone
Silicone compounds are used in thousands electronic systems to protect, bond, seal, and coat electronic components. Its versatility ensures that the compound can perform under extreme operating conditions. Silicone potting technology has made it easier to use and improve the properties. This article will discuss some of the advantages of silicone potting to PCBs. Continue reading to learn more about silicone potting for PCBs.
Silicone or epoxy can also be used for PCB potting. This is because it has high thermal conductivity which dissipates heat from electronic components. Most silicone products are excellent thermal conductors. Some urethane and epoxy compounds have special fillers to improve thermal conductivity. A silicone potting product is preferred, but a polyurethane potable compound is also an option. It is important to choose the right potting material for a PCB in order to ensure the highest quality parts.
China waterproof glue
A popular waterproof glue in China is made from polyurethane. These glues bond two surfaces together without the use of air, creating strong bonds. This waterproof glue is best used indoors and is not recommended for outdoor applications. Make sure to work in an area that is well ventilated when using epoxy-based glue. This will ensure you don’t breathe in any fumes. After the glue has dried, you can sand, paint, or stain it however you like.
Silicone Urethane
Visit https://www.deepmaterialcn.com/, Here are several options for silicone urethane circuit board protection potting. US5520 ™ is one such urethane potting material. 5145(tm) is another option. It is a non-slumping, UV silicone that has a high degree adhesion. Silicone potting compound also offers dielectric barrier and EMI/RFI protection.
The chemical composition is a major difference between silicone potting and urethane. Urethanes can cause eye irritation and trigger asthma attacks. Silicones on the other side are more stable and environmentally friendly. Silicone is used frequently in medical devices where its chemical composition is low-risk. Silicone is an excellent choice for certain applications, despite its low cost.
