Ten Tips for Getting the Best Performance from Photocurable Adhesives

From Ablestik Laboratories
 

 
Photocurable, ultraviolet (UV)- and light-curing adhesives are value-added replacements for traditional adhesives and are essential for many high-tech assembly operations where high throughput and delicate components are required. OEMs and other assemblers are switching to light cure products to meet the need for lower temperature curing and faster setting adhesives and coatings. Here are ten tips to get the best performance from photocurable adhesives. 1. Choose the appropriate adhesive for the application. This involves: • Understanding how the adhesive will be applied • Choosing the right adhesive for the substrates involved • Understanding what performance requirements are necessary. 2. Use a lamp system that provides • Sufficient intensity at the appropriate wavelength • An emission spectrum matched to the absorption of the photoinitiators • Complete coverage of the area to be bonded.
