Cure Test Methods: UV/EB/LED Coatings & Inks
By Jake Staples, technical manager, Wausau Coated Products, Inc. Identifying the point at which a coating is cured is important to maintain consistent physical properties and performance, but it becomes even more critical when potential migration of uncured components is a consideration. Migration testing by extraction can be expensive, and the results are only reliable for … [Read more...] about Cure Test Methods: UV/EB/LED Coatings & Inks
Where Are They Now?
The Q4 2021 Issue of UV+EB Technology introduced us to a group of companies (The UV Band) that worked cooperatively to design, prove and implement a UV-based solution for the base coat of a guitar. The link to the original magazine issue can be found at: https://bluetoad.com/publication/?i=730064. This column provides a VH1-inspired update, “Where Are They Now.” Customer … [Read more...] about Where Are They Now?
LED Boosters to Improve Surface Cure by LED for Litho or Flexo Applications
By Tong Wang, Ph.D., allnex USA Inc.; Steven Cappelle, Ph.D., allnex Belgium; and Paul Gevaert, Ph.D., allnex Belgium Poor surface cure due to oxygen inhibition presents a consistent challenge in LED curing. Amine synergists can provide abstractable hydrogen to mitigate oxygen inhibition and improve surface cure. Three amino acrylates are evaluated as LED boosters to improve … [Read more...] about LED Boosters to Improve Surface Cure by LED for Litho or Flexo Applications
