Doublecure® 200 is a liquid-type non-yellowing photosensitizer. Good solvency proprieties make it ideal for making photoinitiator blends. It is the initiator of choice for coating on wood, metal and plastic as well as UV-cured adhesives where non-yellowing properties are important. This product, when irradiating with UV light, undergoes both of a homolytic and intramolecular type of breakage to generate a pair of free radicals and a bimolecular hydrogen abstraction reaction to initiate the polymerization of UV curable systems.
Its photospeed acting as a photoinitiator is not as fast as Doublecure® 173 for example, but it gives better non-yellowing performance and better surface curing. This product is a light yellow and clear liquid.
