Applications
|
General
|
Chemstab UV-22 is an in-can stabilizer that acts as a polymerization inhibitto help prevent the degradation of UV curable compositions. In addition, it helps to preserve shelf life stability. Chemstab UV-22 is recommended for:
• Printing ink formulations
• Coating formulations
|
|
Processing
|
It is generally not recommended to add more than 2.0% by weight of this additive because this may have a negative impact on the curing performance of the formulations. The final dosage should be determined experimentally inder to obtain an optimized balance between the stabilization effect the curing performance.
|
|
Recommended Concentrations
|
A usage level of 0.2 – 1.5% by weight of the final formulation is recommended. A preferred starting point is 0.5% by weight of the final composition.
|
Storage Conditions
Do not expose to direct sunlight. Store at room temperature below 50°C. Avoid contact with alkaline additives water. The product is stable f2 years, in original, tightly closed containers stored under the above mentioned conditions.
Safety & Handling
The usual safety precautions when handling chemicals must be observed. These include the
measures described in Federal, State, Local health safety regulations, thorough ventilation of the workplace, good skin care, wearing of protective goggles.

应用
阻聚剂 UV-22 是一种罐内稳定剂，作为聚合抑制剂，帮助防止紫外线固化组合物的降解。此外，它还有助于保持保质期的稳定性。
阻聚剂 UV-22应用建议：• 印刷油墨配方• 金属油墨阻聚剂配方• 涂层配方。
建议最终配方的使用量为0.2-1.5%。
一个首选的起点是按最终成分的重量计算的0.5%。
一般不建议添加重量超过2.0%的添加剂，因为这可能会对配方的固化性能产生负面影响。对于最终剂量，应获得稳定效果和固化性能之间的最佳平衡。
