Why Speed Matters in LiDAR Manufacturing
DELO's advanced DELO PHOTOBOND LA formulations solve the fundamental bottleneck facing manufacturers. While traditional silicones and established light-activatable solutions need up to one hour to reach handling strength, the new light-curable adhesives generation achieves this in minutes.
The technology builds on proven silane-modified polymer chemistry with light activation at 400 nm or 460 nm. After one hour, the adhesives reach 1.1 MPa compared to 0.2 MPa for previous solutions, while maintaining essential flexibility for stress-sensitive optical applications.
Your advantages at a glance:
- Up to 5x higher production throughput compared to traditional solutions
- Handling strength is achieved in minutes instead of one hour
- Maintains flexibility essential for optical precision
- Low Young's modulus across automotive temperature range (-40°C to +125°C)
- Improved outgassing performance with condensable outgassing below 0.1%
Perfect for Critical LiDAR Applications
The new formulations excel in both mirror bonding and cover window bonding applications critical for LiDAR systems. Despite accelerated strength development, the Young's modulus remains consistently low across the automotive operating temperature range, preventing stress in precision optical components.
For closed optical systems, outgassing performance has been significantly improved. This makes the adhesives ideal for automotive LiDAR applications where optical clarity is paramount.
Proven Reliability Across Applications
DELO's comprehensive reliability testing confirms long-term durability:
- Aluminum/glass mirror bonding: consistent 5 MPa strength retention
- Aluminum/polycarbonate cover window bonds: 4 MPa performance after 500 hours
- Testing conditions: 85°C/85% relative humidity and thermal shock
