What is the difference between a potting compound and a sealant? Is it the same product?

Many customers have heard of potting and sealant, but they don‘t know if the two products are the same product, let alone what the main differences between the two are. In fact, potting compound and sealant are two different products, but some differences are not easy to spot.

Encapsulants are known for their excellent flow and filling capabilities, and they act as a light liquid before curing, allowing them to easily penetrate into every corner of complex structures such as electronic components and circuit boards for comprehensive and detailed potting. This process not only enhances the integrity of the electronic product, but also significantly improves its ability to withstand shock, vibration, and harsh environments. The curing of potting compound is like a solid armor for electronic products, effectively isolating the intrusion of moisture, dust and corrosive substances in Egypt, and ensuring the long-lasting and stable operation of its internal components. Sealants, on the other hand, focus more on the precise execution of bonding and sealing, and with their unique adhesion and tight fit after curing, they become the key to connection and protection.

Liquidity is different

　　The encapsulant exists in a liquid state before curing, and the viscosity is not high and the flow is good. It can penetrate directly into each crevice and play the role of filling and potting. Whereas, the sealant is less susceptible to flow and can be changed according to the shape of the sealing surface.

The sealing object is different

　　Encapsulant is mostly used to seal and protect electronic components, circuit boards, etc., and the performance is very good. Sealants can be used in daily life to bond and seal.

The specific performance is different

　　After successful curing, the sealant is waterproof, leak-proof, heat-insulating, sound-proof, and shock-proof. Comparatively, the performance of potting compound is more, which can effectively prevent moisture, dust, high and low temperature resistance, corrosion resistance, heat conductivity and insulation. In order to use high-quality products, cooperate with powerful suppliers, and be more assured, not only can focus on potting compound research, but also can provide customized potting compound application solutions, which are widely used and can be used in new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

Can potting compound and sealant be mixed?

　　For industries with low adhesive requirements, potting adhesives can be purchased as well as sealants. Both have some similar properties that can be brought to play. If you have high requirements for certain performance, you need to purchase them in a targeted manner.

Before you buy an adhesive, you should have a detailed understanding of your specific needs. Once you‘ve figured out what you want the adhesive to do, consider whether to buy a potting compound or a sealant. Moreover, the two adhesives are divided into epoxy resin adhesives, silicone adhesives and polyurethane adhesives, etc., and different types of products are suitable for different working environments. Choose carefully and strive to achieve the desired effect.
