UV LED cure is becoming more and more prevalent in several converting areas. UV-curable inkjet has used UV LED cure for pinning for many years. Acrylated amines can be used to either increase UV LED cure speed at existing PI concentrations, or maintain UV LED cure speed at reduced PI concentrations. 

UV cationic coatings present a viable and attractive option to OEMs, sheet metal mills and formable sheet metal fabricators for precoated deep draw steels to present-day conventional sheet metal forming, bending, stamping and/or fabrication operations that require secondary conventional industrial conformal coatings processing, as well as an effective delivery transport mechanism for new pathogen inhibition and biocidal efficacy technologies.

Newly designed low-viscosity oligomers allow the formulation of UV-curable soft-touch coatings without the need for solvent or water diluents.

Additives based on hyper-branched polymers with tailor- made particle-affinic groups lead to very high-performing products to be used in silica matted solvent-free UV-curing coatings.

This revolutionary UV LED curing raises work piece surface temperature less than half of traditional curing methods that utilize traditional UV or arc lights

Automotive customization and energy-curable technology are an excellent complimentary pair. On top of its fast cure, energy curing offers excellent chemical resistance that can pass many of the automotive crème standards and can also be tailored to have a wide variety of properties.

This article describes the development of siliconized UV light-cured coatings.

Ceramic microspheres may offer formulators alternatives in waterborne UV-curable coatings to serve as both a matting agent and functional performance filler.

The alternative matting agents discussed in this article offer a first step to developing new ways of controlling the light scattering properties of radiation-curable coatings.

These new blue-colored resins have been designed with input from formulators, equipment manufacturers and coating applicators, and as a result meet the needs of this sector for increased ease of application combined with high-performance properties.
