| Résumé : |
Tomorrow's industrial coatings, printing inks and adhesives will have to face more severe requirements in terms of solvent emission, drying time, energy consumption and final properties. There is an existing technology that combines answers to all these requirements : the technology of ultraviolet (UV) or electron beam (EB) curing. This paper gives you a general introduction to this technology and covers the following aspects : advantages and limitations, applications, principles, equipment, raw materials costs. |
| Note de contenu : |
- GRAPHIC ARTS, WOOD-COATINGS AND ELECTRONICS ARE THE THREE MAIN APPLICATIONS
- PRINCIPLES : In radiation curing, two curing technologies are used : UV and EB - Essentially two different chemistries are used : free radical and cationic
- OXYGEN INHIBITION CAN BE OVERCOME IN TWO WAYS
- EQUIPMENT : Medium pressure mercury arc lamps are the most widely used UV lamps - Linear cathode type and the scanning type are two types of electron beam equipment
- RAW MATERIALS IN CAMPARISON : Raw materials for free radical curing - Raw material for cationic curing
- COST : A fair comparison is not to compare the cost per kq - No incinerator is necessary - Very low energy consumption for direct energy curing - Investment costs for UV-curing are not higher than conventional equipment
- Fig. 1 : Outline of free radical polymerisation
- Fig. 2 : OUtline of cationic polymerisation
- Table 1 : Formulation of a conventional and a UV-curing coating
- Table 2 : Amounts of water and/or solvent in solvent-based or water-based coatings and printing |
