The term potting means to fill in a circuit board with an insulating liquid. This liquid hardens to protect the circuit board against shock and other environmental factors. This is important for electronic assemblies because of the fact that they are often subjected to shock and temperature extremes. Circuit board protection potting is an ideal solution to protect the components of your circuit board from environmental conditions such as extreme temperature swings. It also offers long-term protection.
Epoxy resin
PCB potting is a critical part of PCB protection. It can ensure reliable operational protection in a variety of harsh environments. Unlike other materials, epoxy resin offers superior chemical, vibration and corrosion resistance. Plasma Ruggedized Solutions’ proprietary two-part electronic potting compound, Kryptos-17(tm), meets these requirements. It has exceptional wetting and curing properties. Consequently, it provides better circuit board protection and longer circuit board life.
Circuit board potting is typically made from urethane or epoxy. The advantages of urethane and epoxy are that they can withstand high temperatures without causing any damage to components. Additionally, both materials offer excellent dielectric barrier and excellent adhesion. However, both urethane and epoxy have their disadvantages. It can be difficult to work with. In addition to the physical limitations, potting compounds are difficult to remove.
Urethane
Urethane circuit board protection potting is a process that provides a protective shell for a PCB assembly. It provides thermal management for electronic components and adds structural strength. To complete the process, a PCB assembly is placed in an appropriate open box. The PCB and components are then immersed in a specially prepared liquid. This potting compound dries to form an encasement that becomes part of the finished product.
The process of PCB potting is similar to that of conformal coating. This process uses organic polymers to provide chemical, thermal, and electrical insulation. This process protects PCB components from physical shock and other harmful elements. It also improves electrical performance. To learn more about the process of potting, visit our website.

Silicone
Silicone compounds are used in thousands of electronic systems to bond, coat, seal and protect electronic components. The compound’s versatile properties ensure reliable performance under a variety of extreme operating conditions. The latest developments in silicone potting technology are designed to improve their usability and range of properties. This article discusses some of the benefits of silicone potting for PCBs. Read on to find out more about the benefits of silicone potting for PCBs.
Another benefit of using silicone or epoxy for PCB potting is its ability to provide high thermal conductivity, which helps dissipate heat away from electronic components. Silicone products are usually excellent thermal conductors, while some urethane or epoxy compounds include special fillers to increase thermal conductivity. While a silicone potting product is generally preferred, a polyurethane potting compound is another viable choice. In any case, choosing the right potting compound for a PCB is essential for the quality of the final parts.
waterproof glue China
Popular waterproof glue China is a polyurethane-based glue. These types of glue bond two surfaces without air, creating a strong bond. This type of waterproof glue is recommended for indoor applications and is not suitable for outdoor projects. When using an epoxy-based glue, make sure you work in a well-ventilated area so that you don’t have any fumes. Once the glue has cured, you can sand it down, paint or stain it as desired.
Silicone urethane
Visit https://www.deepmaterialcn.com/, Here are several options for silicone urethane circuit board protection potting. Among them are US5520(tm), which is an economical urethane potting compound. Another option is 5145(tm), which is a non-slumping UV silicone with a high degree of adhesion. Silicone potting compounds also offer dielectric barrier and EMI/RFI shielding.
A major difference between urethane and silicone potting is the chemical composition. Urethanes are flammable and volatile organic compounds, which can irritate eyes and trigger asthma attacks. Silicones, on the other hand, are less volatile and more environmentally friendly. Silicone is often used in medical devices, where the chemical composition is low-risk. Despite their low cost, silicone is a better choice for some applications.
