Abstract
Production of polymer coatings curable by ultraviolet radiation (UV) imposed on various types of surfaces is applicable in several industries such as printing, paints and varnishes, adhesives and sealants, furniture, automotive and electronics. The key to achieving high process efficiency is to use an effective initiation system. The constant challenge for scientists is to find initiators with absorption characteristics compatible with emission characteristics of commercially used light sources. In addition, the initiator must not generate a coloured product after the polymerization reaction, should be efficient in initiating the reaction and be cheap to obtain. Taking this into account, we propose meta-terphenyl derivatives as highly effective photoinitiating systems for various photopolymerization processes according to free-radical, cationic and hybrid mechanisms. Our photoinitiating systems can to be widely used in all processes where the oxygen access to the reagents cannot be limited, particularly for coating paints and protective layers as well as in rapid prototyping techniques. Other strong points of the presented technology are the followings: - much higher initiation efficiency; shortening of the photopolymerization induction period, and increase of monomers photocured process speed - increase the rate of photocurable polymer layer production lines - optical - advantageous properties, so that they can be used as photopolymerization processes photosensitizers for many monomers - compatibility with UV LEDs, which secure process without ozone emission and heat release - energy savings through an increase in the production rate In this research, we investigated several new derivatives in the role of the two-component initiating system for use in the coating industry.
