LED curing has seen significant growth in recent years and although it provides many benefits, it does have its drawbacks. Low cure speeds and oxygen inhibition are among the chief issues associated with LED curing, either of which can possibly lead to incomplete cure and inferior mechanical properties relative to traditional, broad-spectrum curing.
In light of these problems, our white paper, "Dendritic Oligomers for LED-Curable Formulations", explores the use of dendritic acrylate oligomers in LED-curable formulations. Dendritic materials are known to impart very rapid cure speeds, exceptional chemical and scratch resistance, and high film hardness when cured with traditional methods. With strengths such as these, it seems that dendritic acrylate oligomers are potentially good candidates for use in LED formulations.
