Dendritic Oligomers for LED Curable Formulations
James Aerykssen, Dymax Oligomers & Coatings
Abstract: The present work addresses a strong market demand for oligomers that can be used in LED curable formulations. Dendritic acrylate oligomers, with their hyper-branched, highly functionalized structures, are known to impart excellent properties to traditional UV formulations including increased cure speed, chemical resistance, and scratch resistance. This presentation expands on this knowledge by discussing the properties of coatings formulated with these dendritic materials when cured with an LED light source. As expected, we have found that when cured with LED these oligomers offer very fast curing, possess excellent chemical and scratch resistance, and experience less oxygen inhibition. These oligomers would then be suitable for use in LED-curable pigmented ink applications.
