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...

UV-Curable, Biodegradable Medical-Grade Adhesives

"Is there a UV-curable, medical-grade (safe to use in the body) biodegradable adhesive of any kind on the market right now? If not, would it be possible to formulate the adhesive?"

Dymax does not presently pursue implantable applications for our...

Guidelines for Protecting Light-Sensitive Adhesives from Curing in Dispensing Equipment

Unfortunately, manufacturing facilities that use standard fluorescent lighting sometimes have a problem with the polymerization of UV/Visible light-curable adhesives in dispenser tips and lines. The chemistry of these products make them extra sensitive...

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...

How do I Reverse Syneresis in an Adhesive?

"One of the materials I’m using has exhibited syneresis. What is the best way to reverse the syneresis?"

A few thickened adhesives (VT and GEL grades) occasionally exhibit syneresis. Syneresis appears as a thin film or puddles of low-viscosity adhesive...

What is an appropriate gap size when using DYMAX 204-CTH?

"I would like to attach 72D Pebax extruded tubing into the ID of a Polycarbonate tube. What is the appropriate gap-per-side if I want to use DYMAX 204-CTH UV- curable adhesive?"

The optimum gap size for UV bonding applications (in general) is 0.002-0.006...

What adhesive should I use to bond a polyurethane tube to an ABS adapter?

"Can you recommend the most appropriate UV-curable adhesive to bond ABS connectors to polyurethane tubing in a medical device application? It is a polyether aromatic polyurethane tube to a transparent ABS connector."

For this type of application I...

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...

Removing Oxygen Inhibition From Cured Parts

  "Can oxygen inhibition be removed from cured parts without damage to the fully-cured substrate area? We are looking to change our process to include a nitrogen blanket, but have many components that cannot be completed due to the tackiness on the outer...
