To protect against damage from water, dust, voltage discharge, vibration, and physical contact, potting compounds are used as encapsulants. The potting material is introduced during the electronic assembly and has excellent adhesive properties; as a result, it is very challenging to remove them once they have been placed because they adhere to the surface permanently, making rework impossible. The potting process can be done manually or automatically using meter-mix-dispense (MMD) machinery. The potting compound market is expanding globally due to its perfectly suited properties for electronic applications. Additionally, during the anticipated period, the output of the consumer electronics industry will increase, and miniaturization will become more prevalent. However, it is anticipated that the market growth during the examined timeframe will be constrained by improper potting resin selection for various applications. In the coming years, the key players in the global potting compound market should benefit from the end users' gradual adoption of two-component polyurethane potting compounds.Increased middle-class disposable income encourages the purchase of advanced electronics products, which drives the expansion of this industry.

Potting Compound Market Growth Factors 

Perfectly suitable properties for electronic applications

Potting compounds in electrical and electronic applications areprevalent for an excellent reason. They have advantageous characteristics that shield electrical equipment and electronics from the outside environment. Potting materials have outstanding electrical insulation, super adhesive strength, excellent thermal conductivity and stability, and chemical resistance. Electronic equipment and products are expected to operate at higher temperature ranges as they deliver more power while delivering desired services. Thermally conductive potting materials have developed into an efficient way to manage the heat that accumulates in an electronic assembly. Thermally conductive potting compounds provide a reliable route for the heat to move away from a heat-generating source consistently and toward a metal enclosure because electrical equipment is frequently used in low, medium, and high-voltage applications. This is the main factor causing the demand for potting compounds to increase.Once the potting liquid has been added to the electronic assembly, it hardens, permanently shielding the device from moisture and enabling it to function in harsh environments, ensuring its security.

Increased Consumer Electronic Industry Output And Trend For Miniaturization

The consumer electronics sector experienced a boom fueled by technological advancements and economic reforms, which were visible to the world. The industry is renowned for its ongoing product innovation and widespread uptake by all demographic groups worldwide. The leading cause is an increase in middle-class people's disposable income. As a result, the consumer electronics industry is anticipated to grow in every way. The increase in single-family households led to a massive increase in high-tech appliance sales, benefiting the consumer electronics sector. Because potting materials are used in electronic assemblies to ensure safety, demand for potting compounds is increasing at a rate consistent with rising sales of consumer electronics products. They serve as encasing materials for corrosion, electrical, and thermal resistance. Encapsulants offer minimal curing time in integrated circuits (IC) and printed circuit boards (PCB) by providing the best protection. Due to the demand for portable and smaller-sized electronic devices, miniaturization is one of the most recent trends in the consumer electronics sector.

Market Restraints

Improper selection of potting resin

When choosing the potting resin, extra care must be taken to ensure a high level of protection. To achieve ideal adhesion, specific potting materials require surface preparation and primers. During application, the liquid potting material must flow easily to cover the component and leave no void. Every instance of a discrepancy eventually causes corrosion and component or product failure.One-part, no-mix systems can also be used for potting, even though two-part systems are the norm for epoxy and silicone potting compounds. However, the electronic components may be harmed because they typically cure at temperatures between 125 and 150 ºC. This should reduce the use of these potting compounds in turn. One-part epoxies can also cause thermal damage because they are exothermic.

Market Opporunity

Adoption of two-component polyurethane potting compounds over time

Various electronic devices use potting resins as an encapsulant to shield the device from the environment. Specific uses for electrical potting compounds include protection from mechanical and electrical faults and moisture, corrosion, and electrical short circuits. Some players have begun to offer two-component polyurethane potting compounds to address the issues with using epoxy resin in potting compounds. This is because polyurethane potting materials offer more benefits than epoxy potting materials, including good electrical properties, lower temperature curing, chemical resistance, no odor issues, and low shrinkage. Since polyurethane potting compounds are appropriate for industrial and commercial applications, more businesses are anticipated to start producing two-component polyurethane potting resins in the upcoming years. Therefore, two-component polyurethane potting compounds will soon present manufacturers with lucrative opportunities.
