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...

Effects of UV Curing Energy on Unprotected Areas of a PCB

"Will exposing areas of a PCB board that are not covered by an adhesive or conformal coating to UV curing energy damage the board in anyway?"

Any frequency of energy that gets impinged onto a substrate has two options: it can get reflected, in which...

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...

Cracking in PC Bonding Application

"We are observing a cracking problem in the bonding of a PVC tube and component of PC-144R with a 50% Cyclohexanone + 50% Tetrahydrofuran solvent mixture. Please suggest an alternative solvent for bonding the above component. Also describe why the...

What wavelengths are associated with depth of cure vs surface cure?

Depth of cure is typically accomplished using long wave, UVA light (320-390 nm). Surface cure is typically done using short wave, UVB light (280-315 nm). For more information on curing with light, see Dymax's Comprehensive Guide to Light-Curing Technology

What solvent should I use to remove 1184-M-T?

"We use 1184-M-T, 1184-M-B, and 1184-M-VT epoxies for various uses. What is a good solvent that can take apart lenses glued together using 1184-M-T adhesive?"

If your lenses are made of glass you have several options, as glass is resistant to the solvent...

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...
