This article demonstrates the equivalence of a simple calculation for crosslink density to more sophisticated methods developed by others. By virtue of the method's simplicity it has been easily extended to more complicated UV-curing systems and serves to easily determine the effects of prepolymer architecture on the crosslink density in the cured film.
ChemQuest Technology Institute (CQTI), in partnership with Heraeus Noblelight America, has begun scheduling trials on its newly installed, state-of-the-art, microwave-powered and UV LED wide-format curing systems
UV cationic coatings present viable and attractive options to OEMs, polymer coaters, extruders, contract coaters and/or thermoformers to improve functional and/or physical properties for formed polymer film/sheet as well as an effective delivery transport mechanism for new pathogen inhibition and biocidal efficacy technologies.
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.
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.
