What is the difference between sealant and hot melt adhesive? Understand clearly in one minute!

In manufacturing industries such as electronics, automotive, and home appliances, potting adhesive and hot melt adhesive are often used for sealing, fixing, insulation, and other processes. But many people are not clear about the difference between these two types of glue. Today, Elaplus will explain their definitions, application scenarios, advantages and disadvantages, and selection suggestions in one go 👇 🔍 What is sealant?Potting compound is a liquid two-component or single component adhesive that can flow and completely encapsulate electronic components. After curing, it forms an elastic or rigid body with properties such as waterproof, moisture-proof, high and low temperature resistance, insulation, and chemical corrosion resistance.📌 Typical applications:LED driver power supply encapsulationTransformer, power module, sensor packagingAutomotive Electronic Control Module (ECU) Packaging🔥 What is hot melt adhesive?Hot melt adhesive is a thermoplastic adhesive that melts after heating and quickly solidifies after cooling. It is usually in the form of solid rods or particles and is commonly used in automated dispensing or spraying equipment.📌 Typical applications:Packaging industry sealingFurniture edgingQuick bonding of plastic parts for household appliances📊 Potting compound vs hot melt adhesive: key differences at a glanceItem                                                     potting compound                                                   hot melt adhesivePhysical state                                    liquid, needs to solidify solid                                  heated and melted for useCuring method:                                chemical reaction…
