Radiation curable materials - Principles and new perspectives

Increasing environmental concerns and the ensuing legislation to cut emissi ons of volatile organic compounds (VOCs) have been major driving forces beh ind the development of radiation cured coatings over the past 25 years. Tod ay radiation cured coatings are known for their good overall performance an d their excellent resistance against chemical and physical surface damages. Advanced photoinitiator systems allow the light stabilisation of UV-curabl e formulations and the outdoor application of the coating. The rapid curing , combined with the possibility of immediate processing of the coated objec ts opens the way for radiation curing - in 100%-, water based-, and dual cu re systems as well as for radiation curable powder coatings - for a wide va riety of application.
