Bonding Solutions for Low Surface Energy Substrates

Edward Petrie – Feb 27, 2017

Bonding Low Energy Surface (LSE) MaterialsCertain polymeric substrates, such as polyolefins, fluoropolymers, and silicone rubber are difficult to bond and present challenges to both the formulator and the end-user. The main reason that these materials present problems is their low surface energy.

The low surface energy simply prevents conventional adhesives from making intimate contact with the substrate surface and this reduces adhesion.

This article will help you understand why these substrates are difficult to join and offers insight into possible solutions including:

  » Optimizing interface
  » Appropriate surface treatment processes
  » Right selection of adhesive system

Corona is good for flat and plane materials.It last for a very limited time. TACKTREAT or Plasma+TACKTREAT are als for 3D materials.It last much longer up to 30 days or even more ,depending on the material.Very important is to use the rigth,adopted and devolped to the process waterbased UNIBOND WB adhesives

I miss there in the treatment the - PLASMA - TACKTREAT-UVC - Combination of PLASMA and TACKTREAT all VOC-free use with waterbased UNIBOND WB adhesives 1com,blocked or 2 comp. This are already in use and published
