Whether you're planning to install a car trim or attach a new gasket, you'll most likely need to use some sort of adhesive compound. But with so many choices these days, selecting the right one can get downright confusing. So to help you figure out the right adhesive, here's the lowdown on what you should consider based on specific automotive applications.
Adhesive for vehicle interiors
If you're looking for an adhesive compound to be used on car interiors, choose one that can hold out against vibration, scratches, and exposure to UV light. A product that provides secure adhesion to a variety of materials such as composite substrates, rubber, plastic, and glass is a good choice because a vehicle's interior usually consists of different materials.
Epoxy- and silicone-based adhesives are your best bets because they're perfect for overhead assemblies and headliners, airbags, consoles, car seats, sensors, and display units.
Adhesive for car electronics
For vehicle electronic systems, stick to adhesives made from polyurethane, silicone, polysulfide, epoxy, and UV-resistant compounds. These types provide improved resistance against chemicals, moisture, and extreme temperatures. They also enhance an electronic assembly's mechanical strength and durability. The right adhesive can help you make the most of your car's vehicle stability control, navigation, transmission control, anti-lock brake, and engine control systems.
Adhesive for structural parts
When dealing with flanges for the deck lid, hoods, doors, dashboards, and roof panels, invest in an epoxy-based adhesive that can adhere to various substrates such as magnesium, steel, and aluminum. To make sure it securely glues various hard surfaces together, the adhesive should provide proper stress distribution, properly fill in gaps, be solvent free, have a wide temperature range, and be able to bond surfaces with various contraction and expansion specs. High resistance to chemical and moisture are also important factors since you'll be using this adhesive compound on parts that are usually exposed to harsh external elements.
Adhesive for lighting assemblies
When installing or fixing busted connectors, housings, or any type of automotive lamp, choose a sealant or adhesive that is highly resistant to UV light, extreme temperatures, vibration, impact, and harsh weather conditions. The right adhesive should also be able to bond plastic, metal, and glass surfaces together. It shouldn't contain solvents or cause lamp lenses to yellow or fade.
Adhesive for powertrain components
Powertrain parts such as intake manifolds, water pumps, engine covers, and radiators need a silicone- and epoxy-based adhesive that's tough, flexible, and can offer thermal stability. Keep in mind that such components are regularly exposed to the harshest conditions and are some of the most hard-working parts under the hood. For increased lifespan, an ideal adhesive should also have excellent heat dissipation capabilities and fast curing properties.
Adhesive for vibration and noise management
If you're looking for an adhesive compound that can help reduce vibration and noise, invest in a urethane-, silicone-, and epoxy-based product designed to absorb noise and vibration. Other factors to look into include quick curing capabilities, superior resistance to chemicals, and excellent bonding strength. With the right product, you'll be able to get rid of buzzing, rattling, and squeaking noises that can come from arm rests, alternators, engines, and HVAC assemblies.
