Sealing materials play a crucial role in multiple industries due to their excellent properties. 

Building Waterproofing and Energy Conservation: In roof waterproofing, materials like modified asphalt sealants are used to repair cracks and prevent water seepage. For window and door installations, silicone and polyurethane sealants fill the gaps, providing waterproof and thermal insulation effects. In the joints of concrete structures such as bridges and roads, polysulfide sealants with high elasticity are used to adapt to the expansion and contraction of concrete caused by temperature changes, ensuring the integrity and waterproofing of the joints.

Electronic Equipment Protection: Epoxy resin or silicone potting adhesives are used to protect circuit boards from moisture and provide insulation. UV - curing adhesives or thermal conductive silicone gels are used to seal sensors and connectors, fixing the components firmly and preventing them from being affected by external factors.

Transportation: In automobile manufacturing, epoxy resin or PVC sealants are used to seal the welding seams and sheet metal joints of the car body to prevent rust, and silicone or fluororubber is used to seal high - temperature components such as engines and fuel tanks. In the aerospace field, polysulfide or fluorosilicone rubbers are used to seal the cabins and fuel tanks of aircraft, which can withstand high pressure and extreme temperatures.

New Energy: For solar panels, weather - resistant silicone sealants are used to seal the frames to protect the internal components. For battery packs, flame - retardant adhesives are used for encapsulation, which not only play a sealing role but also have flame - retardant properties, improving the safety of battery packs.
