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...

Is Surface Preparation Needed When Applying a Light-Curable Material?

"How should a substrate be prepared or treated prior to applying a light-curable material?"

Cleaning substrates prior to the application of a light-curable material is almost always a best practice. Removing contaminants allows for the best wetting of...

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...

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 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

Bonding a Steel Cannula onto an Opaque PP Hub

"I’m looking for a UV-fixating adhesive to bond a steel cannula onto a polypropylene hub. The hub will be plasma or corona treated prior to gluing to increase the bonding performance and the hub will have annular rings as well. However, since the...

What is the Smoke Coming off the Light-Curable Adhesive?

"I see smoke coming off the light-curable adhesive…what is it?"

Before we can answer this question we have to first understand what it’s not. By definition1, it’s not smoke or vapors or outgassing.

What you really are seeing coming off of the curing...

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...
