Radiation curable compositions

摘要

The use of bio-derived products will increasingly become attractive as petrochemical-derived materials increase in cost. Bio-derived cyclic ether polyols can be obtained from various crops and present a unique chemical structure that could fulfil the need for a source of safer and more sustainable radiation cured resins. The non-aromatic structure of these derivatives provides a high tensile modulus and high glass transition temperature. For instance, isosorbide di(meth)acrylates show unexpectedly high cure speeds combined with low viscosities and acceptable inks and coatings properties. There is a particular need for renewable compounds of oligomeric or polymeric nature that can replace bisphenol A.
