Dual curing (UV and thermal) systems can be performed by using blends of the classical resins, like acrylated terminated oligomers and polyisocyanate/polyol combinations. The simplest approach of just combining the individual molecules of multifunctional acrylates, polyols and polyisocyanates results in the formation of interpenetrating networks. Dual curing systems of acrylates with thermal and photo-reactions were studied to understand the effect of curing sequence on reaction kinetics. In order to evaluate structure-property relationships between cross-linked UV curable oligomers and diluent monomers for dual curing systems, the understanding of the relationships between curing conditions, chemical structure, acrylate monomer functionalities, and network properties are investigated. Some fundamental influencing factors such as chemical composition, cure extent, and crosslink density on the main properties, like thermal and mechanical behavior, are discussed. |
