释放固化潜力

两种热固化化学品，用于有机硅离型涂料产品，满足您所有的应用需求。

加成固化

加成固化化学品通过铂或铑催化，已成功应用于无溶剂、溶剂型和乳液产品。

铂催化剂

铂催化剂可在低温到中等温度下快速固化，具有在规定温度范围内最大程度延长镀液浴液使用寿命的额外功能。

优点

生产效率更快
在低温下更完全固化
不易发生有机硅迁移
不可逆，无阻塞
不需要后固化，可以实现双面差异离型和在线涂布应用
涂层更耐用，离型更稳定和可预测
控制性能的途径更多控制性能的途径更多

缺点

更容易出现催化剂中毒：
- 胺
- 硫化物
- 磷化物
- 有机锡盐
有可能与丙烯酸相互作用

铑催化剂

铑催化的加成固化涂料如何在陶氏独有？

优点

不与大多数粘合剂相互作用。
优异的丙烯酸稳定性
相对较难出现毒性

缺点

与铂催化涂层相比，对基材抑制不敏感
固化速度更慢，需要更高的温度
不适合温度敏感型基材 
不适合食品接触应用

冷凝固化

锡催化剂

通过锡催化，缩合固化化学品是一种具有成本效益的解决方案，可保持多功能性和稳定性。 

优点

涂层坚固耐用，可抵抗基材抑制和催化剂中毒
最大程度减少粘合剂相互作用

缺点

后固化的必要性通常排除了双面和在线涂布应用
可能会发生阻塞
有机硅迁移的风险更高
锡和橡胶具有轻微的相互作用 - 锡催化涂料不太会与SBR粘合剂出现相互作用
