AOI-VM is highly hazardous and can corrode eyes, mucous membrane and skin. Therefore, observe the following precautions.
1)
Give regular education to operators regarding the toxicity and reactivity of Karenz AOI.
2) Be careful to avoid direct contact of skin, eyes, or clothing with Karenz AOI, make sure not to inhale vapor.
3)
In case Karenz AOI has splashed on clothing, take the clothing off immidiately. As for skin, wash the affected area thoroughly with water. Then wash with soap and water. Contaminated clothing should be disposed off.

Curing condition
- Initiator ： Irg184, 5mol%
- UV exposure ： Ultra high pressure mercury lamp,25mW/cm2
Curing method
Dissolve the monomer in a solvent and create a coating film on the PET film with an applicator. After dry with 80℃×0.5hr, UV irradiation.
Result
It evaluated on the time it took for the polymerization rate to reach 50%
UV Curability: ｢Karenz AOI｣ > ｢Existing acrylate｣ > ｢Karenz MOI｣ > ｢Existing methacrylate｣
can scroll| Karenz AOI | Acrylate | Karenz MOI | Methacrylate | |
|---|---|---|---|---|
| Time for the polymerization rate to reach 50% ( sec ) | 10 | 20 | 72 | >200 |
It shows higher reactivity than the aliphatic isocyanates IPDI and HDI, and shows the same reactivity as aromatic isocyanates.
