For high-quality automotive lamp assembly, lighting manufacturers trust our adhesives for their design requirements and production processes.
There are two main applications when OEM dealing with housing in automotive lighting industry:
- Bonding Lens to Housing
- Gasketing for Lens Cover
- Residues Removing and Surface Preparation
And for special positions and other assistive lamps such as Head/ Fog lamps, Tail Lamps, Center High Mount Stop Lamp (CHMSL) Third Brake Lamp, we have more than two:
- Foam Gasketing
- Signal Lights
The main consideration when choosing adhesive for the light housing assembly
- Process: One-component or Two-component Adhesive, Hot-applied or Cold-applied Adhesive
- Fast and high green strength allows short cycle times and quick leak testing
- Excellent durability and high heat resistance
- Low emission (fogging) technology
For high-quality automotive lamp assembly, lighting manufacturers trust PROSTECH adhesives for their design requirements and production processes.
