Demands on coating materials in terms of cost efficiency, optimized cycle times and VOC emissions have changed significantly during the last 10 years. Industry has offered several solutions to match today’s needs for new coating materials. In terms of short cycle times, reduced VOCs and outstanding film properties, radiation-curable coatings show great potential. This technology offers manufacturers the possibility to formulate highly versatile coatings for nearly every field of application.
Compared to conventional coatings (i.e., waterborne 1-pack or 2-pack systems), radiation-curable coatings have different challenges in formulation and curing. Many of these challenges are caused by the curing mechanism.
