Company Profile

Efsen Engineering A/S was founded in 1986 by Karin Efsen with the idea of marketing electron beam curing (EB) in the Nordic countries. In 1988 a number of other agencies were added with the technology related UltraViolet lamps and UV measuring equipment. Since then the company has grown to 8 people and covers all areas within sales, design and construction, service and consultancy within industrial use of radiation. We are distributors for the following leading equipment manufacturers:

  • Fusion UV Systems, Inc - Microwave powered UV lamps
  • EIT, LLC - Radiometers
  • UV Technik-Meyer Gmbh - UV lamps and components
  • Wallenius Water AB - Water disinfection systems
  • PCT Engineered Systems, LLC
  • EXFO Life Sciences & Industrial Division

We have a well equipped laboratory with all types and combinations of UV lamps, spectral outputs and powers along with instruments for the complete process verification available for our customers for tests on site or in our laboratory.

Our goal is to be in the forefront of developments within applications of the UV technology. This knowledge combined with supplying equipment from the leading equipment manufacturers in the world makes our company the best UV partner for those customers who already use UV and those who are investigating UV.

 

 

   
 

Abstract

Light-cure adhesives offer a wealth of advantages, including very fast cure time and low energy use. The major benefit of ultraviolet (UV) curing is that it is a cure-on-demand process. The adhesive will not cure until the UV light hits it, and when that occurs, it takes only seconds to form a complete bond. The process is fast, solvent free, and economical. UV curing has come a long way, particularly in the area of automated assembly, as a cost-effective method for bonding medical devices. Several years ago, UV-cured adhesives were thought to have limitations compared with other bonding methods, but recent developments in UV chemistry and cure-system hardware have greatly expanded the applications for UV curing.
