Dielectric Performance for Electronic Applications using UV-Curable Chemistries
By Neal T. Pfeiffenberger, Ph.D., Sartomer Americas UV-curable electronic materials require a unique set of expertise in resin formulation, processing and end-use properties. Commercial uses for UV-curable electronic products include conformal coatings, potting, photoresists, display materials and adhesives, as well as various 3D printing applications. This paper will focus on … [Read more...] about Dielectric Performance for Electronic Applications using UV-Curable Chemistries
The Problem of High Viscosity Oligomers – Part 1
People new to UV/EB polymerization quickly learn that most of the oligomers used in energy-curable formulations have very high viscosities, often more than 1 x 106 centipoise (cP). A classic example of such a highly viscous material is an acrylate-functional epoxy oligomer based on the diglycidylether of bisphenol-A (DGEBA). Figures 1 and 2 depict the molecular structure of … [Read more...] about The Problem of High Viscosity Oligomers – Part 1
Comparing EB and UV: Common Questions
If you’ve ever attended a RadTech conference and/or read an issue of UV+EB Technology, you surely know that ultraviolet (UV) and electron beam (EB) are similar technologies that also are very distinctly different. The old adage of apples and oranges applies quite well: UV and EB are both types of radiation polymerization (i.e., types of fruit), and there are instances where the … [Read more...] about Comparing EB and UV: Common Questions
