Photoinitiator PBZ function
Suggested levels of use are 0.5–3% w/w Speedcure PBZ together with 2–5% w/w Speedcure EDB or DMB (quantities vary depending on individual formulations and applications).
Photoinitiator PBZ Usage
1. photoinitiator PBZ is a highly efficient free radical (II) type solid photoinitiator, mainly used with tertiary amine synergist for unsaturated prepolymer (such as: acrylate) UV curing.
2. photoinitiator PBZ belongs to the long-wave absorbing molecular structure of the initiator, mainly used in colored UV curing formulations as a light-curing initiator.
3. PBZ unique odorless characteristics, can be used in direct contact with food, widely used in a variety of food packaging UV ink, varnish and other systems have strong absorption properties. The recommended dosage is 2-5%w/w.
