Doublecure® BDK is a highly efficient photoinitiator where inherent yellowing is not important. High photospeed combined with improved shelf life helps make it the initiator of choice for many applications, including coating on wood, metal and plastic as well as photo-resistant dry film. Doublecure® BDK, when irradiating with UV light , undergoes a homolytic and intramolecular type of breakage to generate a pair of free radicals to initiate the polymerization of UV curable systems.
It does not require hydrogen donor to initiate its radicals. However, its radicals are very sensitive to oxygen in the air. Because its polymerization end products contain quinone type of compounds which result in the yellowing effect, its application has been limited. It is usually used to initiate polymerization of systems based on unsaturated acrylic monomers as reactive diluents.
