As regulatory pressures increase inside the world of food packaging, especially in regard to monomers, the market has begun to turn to other options such as waterborne resins and polyurethane dispersions (PUDs).These products can be made into suitable solutions for food contact applications, which is illustrated through comprehensive migration tests and compliance with the current food packaging regulations.Their inherit low viscosity allows them to be the perfect partner for inkjet applications where low viscosity is a vital component of the final formulation.This chemistry also lends itself to re-dispersibility in water which is also a necessary component for these markets.Data on the performance of these systems will be presented, using LED curing methods to match today’s market needs.

Mercury, LED, and Excimer UV Curing Systems

UV curing is a broad purpose manufacturing tool. It is utilized by manufacturers to rapidly polymerize inks, coatings, and adhesives applied to diverse material substrates and constructions often in the form of sheets, webs, assemblies, and fully formed products. UV curing processes enable manufacturers to create an extensive range of desirable surface and bonding effects on the products they produce. This presentation covers the fundamentals of widely used UV curing systems including mercury, LED, and excimer.

Is UV/EB Sustainable?

UV/EB curing is often considered green technology because of it's low VOC and low energy cure profile. In this presentation, we will explore UV as a sustainable solution and the ability UV technology to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Over Print Varnishes (OPVs) Cured by LED

Insufficient surface cure is a known issue for thin coatings cured by UVA LED for printing applications. Because of thin coating thickness (2~3 µm) and low viscosity, over print varnishes (OPVs) usually encounter poor surface quality when cure by UV LED. To overcome this challenge, we studied various classes of photoinitiators (PIs) with and without amine synergists in 100% solid OPVs and compared their cure response with 395 nm and 365 nm LED lamps. Additionally, we evaluate UVA alone and in combination with UVC LEDas possible solution to the challenges of surface cure for UV LED cure systems.
