Cure Test Methods for Coatings and Inks / Structured Urethane Acrylates in LVT Applications

JUNE 2023

CURE TEST METHODS: UV/EB/LED COATINGS AND INKS

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 coatings which have the same level of cure or greater.

STRUCTURED URETHANE ACRYLATES IN LVT APPLICATIONS

Free-radically cured acrylate coatings are known for their fast cure response and enhanced performance properties when compared to conventional thermoplastic coatings. This is, in part, due to the presence of cross-linking, which has been known to improve properties such as stain resistance, hardness and chemical resistance.

NEW CHAIRS NAMED TO RADTECH SUSTAINABILITY COMMITTEE

Sustainability was the focus of meetings at RadTech's recent BIG IDEAS for UV+EB Technology conference. In addition, RadTech's new sustainability site aims to be a streamlined way to understand the whole of the organization’s sustainability missions in one easy place. Finally, the committee's co-chairs have announced they are rotating out, and two have been named to take their place.

UV+EB QUARTER 3 ISSUE TO INCLUDE BUYERS RESOURCE GUIDE

The 2023 third-quarter issue of UV+EB Technology will include the only Buyers Guide of its kind for products and services offered to those companies involved with ultraviolet and electron beam curing technologies. This guide will reach more than 11,500 readers through its print and digital distribution.

LOW-ENERGY ELECTRON BEAM BIOBURDEN REDUCTION AND STERILIZATION

Electron beam has been used to cure coatings and cross-link films, but did you know that it can sterilize, too? Radiation-based bioburden reduction and sterilization methods have been used commercially for several decades. These methods work by harnessing ionizing radiation to break bonds within microbial DNA.
