Adhesives that can be cured in seconds with UV light have been standard in industrial manufacturing for some time. Discharge lamps having a relatively wide emission spectrum used to be the standard technology. These days, LED is the leading UV technology for fast and reliable curing of adhesives for the following reasons:
- High intensity, yet compact dimensions
- Long lifetime (20,000 h and more)
- No warm-up
- No substrate heating
- Narrow, well-defined emission spectrum
- High energy efficiency
Polytec PT offers UV LED sources for serial manufacturing processes as well as for manual or semi-automated production. Polytec lamps feature high light intensity, despite their compact dimensions.
Polytec PT offers a comprehensive range of UV-curing and dual-curing adhesives (UV plus second curing by heat or moisture) for a wide variety of applications. Our products are formulated so that they can be cured at either 365 nm or 395 nm.
