Automotive hot melt sealant is a type of adhesive that is applied molten and solidifies when it cools to make a strong bond. Automotive hot melt sealant is used in a variety of applications in the automotive sector, including.
Sealing the gaps between metal car body components such as doors, hoods, trunks, and roofs. This keeps water, dust, noise, and exhaust gases from entering the passenger compartment and improves the vehicle's aerodynamics and fuel economy.
Bonding various materials such as plastics, metals, textiles, foams, and rubber in the car's inside and exterior. This improves the car's aesthetics, comfort, and safety.
Assembling and encapsulating the battery system components for electric and hybrid automobiles. This shields the battery from moisture, heat, and vibration, enhancing its performance and longevity.
The advantages of automotive hot melt sealant over other forms of adhesives include:Rapid curing and strong green strength minimise production time and expenses.
High elasticity and flexibility, allowing for thermal expansion and contraction of the substratesHeat, moisture, chemical, and UV radiation resistanceLow or no emissions of volatile organic compounds (VOCs), reducing environmental impact.
The following are some examples of common automotive hot melt sealants:Polyurethane (PUR) is a hot melt reactive sealant that cures by reacting with moisture in the air or on the substrates.
PUR sealant offers excellent strength, flexibility, and adherence to a variety of materials. It is used to bond plastics, metals, textiles, and foams in the car's interior and exterior.
Polyolefin (PO) is a non-reactive hot melt sealant that cures during cooling. PO sealant has a low viscosity, strong temperature stability, and good adherence to materials with low surface energy. It is used to seal metal joints in automotive bodies.
Silicone is a hot melt reactive sealant that cures by reacting with moisture or catalysts. Silicone sealant offers a high degree of flexibility and elasticity, as well as resistance to heat, moisture, and UV radiation. It's used to put together and encapsulate battery components for electric and hybrid automobiles.
The Global Automotive hot melt sealant market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Dowsil EA-4600 HM RTV is a type of silicone hot melt sealant produced by Dow Chemical Company. It is a reactive hot melt sealant that cures by reacting with moisture in the air or on the substrates. It has the following features and benefits.
Instant green strength: It forms a strong bond immediately after application, which allows for faster processing and handling of the assembled parts.Neutral cure RTV adhesive: It does not release any acidic or alkaline by-products during curing, which prevents corrosion or staining of the substrates.
Primerless adhesion: It can bond to various materials without the need for surface preparation or priming, such as glass, plastics, metals and other silicones.Long open time and pot life: It has a low viscosity and a high thermal stability, which means it can be applied for a long time without losing its properties or performance.
Service temperatures from -50 to 300°F (-45 to 150°C): It can withstand a wide range of temperatures without cracking, softening or degrading.Can be used with standard hot melt dispensing equipment: It can be applied by roller-coater, film, spot, bead or spray application using melting equipment.
Allows for UV inspection of adhesive bead for quality control: It contains a UV tracer that makes it visible under UV light, which helps to check the uniformity and consistency of the adhesive application.
Dowsil EA-4600 HM RTV is designed for PCB system assembly applications, such as bonding housings, connectors, sensors and modules. It offers protection from moisture, heat and vibration for the electronic components.
