In automotive manufacturing, precision and reliability are everything. You’re responsible for people's lives and safety on the road. If a small component fails, it can ripple across production lines and lead to costly repairs, recalls, delays, and safety risks.
A major automotive manufacturer faced that challenge within one of its exterior assemblies. The double-sided tape used in production couldn’t accommodate the varying tolerances between parts—causing poor surface contact, visible gaps, and field failures over time.
Seal Bond stepped in to help, delivering a versatile, durable, proven solution for current repairs and future production.
The Challenge
The manufacturer’s existing double-sided tape performed inconsistently. It was effective in some applications but struggled when part tolerances varied. This caused uneven gaps that weakened the bond, ultimately resulting in product returns from the field.
To solve the issue, the manufacturer needed a bonding material that could:
- Fill variable gaps between mismatched or uneven parts
- Bond to multiple substrates, including stainless steel, plastics, and leftover tape residue
- Deliver long-term weather and UV resistance for exterior use
- Withstand vibration, temperature swings, and environmental stress
The solution would have to integrate seamlessly into their manufacturing process—fast, clean, and consistent.
Our Solution
After a thorough evaluation, the automotive manufacturer partnered with Seal Bond to find a high-performance adhesive that could replace the unreliable tape.
Seal Bond’s technical team recommended Seal Bond® 105 High Performance Adhesive/Sealant, a hybrid polymer formulation known for its versatility and proven success in demanding industrial applications. Its strengths include:
- Fills tolerance gaps easily: Its smooth dispensing allows it to adapt to variable gap sizes without extra cleanup.
- Bonds to multiple substrates: Performs even over acrylic tape residue, stainless steel, and plastics.
- Remains permanently elastic: Handles movement, vibration, and thermal expansion without cracking.
- Built for harsh environments: Resistant to UV exposure, weathering, and long-term stress.
Seal Bond’s technical specialists worked with the manufacturer’s engineering team to test and validate SB 105 in multiple use cases, ensuring reliable performance across repair and new production applications.
