Safer initiation of photo-induced radical polymerization
Market Data
Most radical photoinitiators are activated by the use of UV light, which is dangerous to manipulate (it can generate DNA damage and eventually lead to cancer). Our photoinitiators can work with less energy consuming and safer visible light, to provide almost colourless polymers.

Project terminated, no further activities are carried out
Technology Status
Visible light-triggered photoinitiators
UV technology well stablished Some visible-light activated photoinitiators (BAPO) Slow activation of the photoinitiator
The technology has been abandoned due to: residual colour left in polymer; slow reaction in comparison with benchmark photoinititators

Safety: Without using UV all the problems related to operating with UV light are avoided, as exposure of individuals to UV radiation causes health concerns. Safer Health applications of photopolymerization. Non-colored product: most photoinitiators operating under visible light are colored systems, which typically results in poor control over the aspect of the cured or dried product and does not allow for the production of non-colored products. Light from the visible spectrum: It absorbs light in the visible range of the spectrum, in particular in the 400-500 nm region (blue light). This advantageously allows for avoiding the use of UV light in polymerization applications. Control of the growth of the polymer: The growth of the polymer can be controlled by switching on and off. Accessible and cost-effective: The synthesis of initiators is Accessible and cost-effective. Current state of the art photoinitiator compounds are being scrutinized by regulatory authorities, which calls for alternative solutions.
