A new series of oligomers for PSAs

A new series Chemists have developed a new series of oligomers which are finding applications in of oligomers high speed in-line UV-curable PSA labelling applications. Other PSA applications are also for PSAs expected to use these oligomers after proper research and testing. 

The search for such oligomers was driven by the concerns about the adhesive performance and long-term stability of radiation-curable PSAs It is important to reiterate that the greatest influence on PSA performance comes from proper curing of the PSA. 

To better understand the PSA chemistry, there is a need to define what is known as the optimal process conditions. This refers to the optimal energy range where the cured adhesive is able to achieve the best possible performance specifications at a desired level of thickness. The same processing conditions cannot be used for the same adhesive with twice the application thickness it becomes necessary in that case to define different process conditions for that thickness. The optimal process conditions also depend on variations in lamps, photoinitiators, and oxygen inhibition. 

In various types of adhesives, PSAs are specifically highlighted as one of the areas with the greatest potential for widespread application, with growth rates expected to be significantly high to 2010. The key reasons pointed out by industry experts for such positive expectations are
