5 Factors to Consider Before Selecting an LCM

Fast on-demand curing, cost and energy savings, environmentally friendly are just a few of the many benefits to using light-curable materials (LCMs) in the manufacturing process. But that process could come with some headaches if good process control...

Reversing Adhesive Crystallization

"How can I reverse adhesive crystallization? Will the adhesive be compromised in any way?"
Only a very small number of adhesives are susceptible to crystallization and the likelihood of this phenomenon actually occurring is slight. If you do experience...

The Effects of Overexposure During the Curing Process

"Will overexposure during curing have any effect on the adhesive?"
 
The effect of underexposure is obvious… incomplete cure. The effects of overexposure are more complex. Double and triple exposures (two to three times the dosage required to cure)...

What adhesive should I use to bond an epoxy-coated magnet to a copper-clad FR4 PC board?

"We need to glue an epoxy-coated magnet to a copper-clad FR4 PC board. The UV-cure glue needs to resist mechanical shock without cracking. Any Ideas?"  

Dymax offers 6-625-SV01-Rev-A, a flexible light-curable adhesive with secondary heat cure and...

Light-Curable Adhesives and Permanent Implantation

"Is there a UV-curable adhesive that when cured conforms to USP Class VI and passes ISO 10993 requirements for permanent implant?"
 
Unfortunately, not that I am aware of. Technically, most light-curable adhesives are acrylated urethanes or epoxy-based...

Creating Smooth, Tapered Edges with Adhesives

"I have an application where the cuff is glued to the tube and I require a smooth, tapered transition between the cuff edge and the tube.

Writing will take place over this area; that is why I need the smooth, tapered glue connection."

How does humidity affect the adhesive?

In the uncured state, humidity under most normal conditions of 0-70% Relative Humidity (RH) has no impact on a light-curable adhesives . It does not affect the curing time, chemical properties, or adhesion to the substrate. At 70% RH or higher, we...

Determine When Full Adhesive Cure is Accomplished and Create a Robust Light Curing Process

"I am trying to understand the UV-curing process. How can I determine when an adhesive is fully cured? What are the critical parameters that I need to control in order to gain good consistency for the curing? Also, I was trying to cure some adhesive on a...
