The Advantages of Advanced Gasketing in Automotive Applications
You wouldn’t want a gas leak in your house – the same holds true for your car. The auto industry holds this same quality-focused mindset, and is taking on this notion to ensure that lighter, reliable cars are held to the highest quality standards.
The Effects of Lightweighting
2025 CAFE standards are influencing a host of lightweighting trends from interior design to changes to the paint shop process. Powertrain designs are also being affected in major ways. A combination of new materials such as plastics and aluminum, as well as traditional materials like compressed graphite iron are being incorporated. This allows for lighter engine designs, but also requires gasketing that can handle the different thermal expansion rates of these materials in order to create a seal and protect against engine oils.
AEV/EE also have new gasketing requirements due to increased electrification, hybrid systems, and 48-volt systems. These require sealing against cooling system fluids and protection of connectors.
Gaskets and seals are crucial in preventing fluid and gas leakage in vehicles, and need to be airtight. They must be altered to work with lighter materials to achieve a higher level of sealing performance, longevity and cost effectiveness. In fact, due to the increase in vehicle production across the globe, the U.S. gaskets and seals market is expected to expand by 3.8 percent annually through 2018 to the tune of $10.6 billion.
Henkel Advanced Gasketing Solutions
To continue to address industry needs, Henkel has introduced new moisture-cure polyacrylate gaskets. They’re highly resistant to all automotive fluids and conditions, ensuring an airtight endurance.
These products provide an excellent cost-to-performance ratio. They are a low-cost gasketing solution (reducing material costs as much as 95 percent compared to conventional molded gaskets) while offering superior performance. They also offer higher joint movement capabilities than alternatives, and automated robotic application allows for lower production cost, less material usage and increased reliability.
Henkel recently hosted a smart chemistry spotlight event that focused on its advanced gasketing technologies, including:
- LOCTITE 5188 – highly flexible anaerobic gasket, designed to function in the most demanding applications with superior adhesion and flexibility after heat cure.
- LOCTITE 5810 – one solution that can seal automotive engines, transmission and driveline application.
- LOCTITE 5970 – a RTV silicone, neutral curing that can be used in engine, gearbox, transmission and axle construction.
Attendees were able to see these technologies first-hand. If you missed the event, here’s a glimpse into what we covered:
