Applications
It is used as a neutral curing agent in silicone sealant formulations. Normally, it will be combined with MOS or VOS to achieve higher reactivity, shorter skin formation times and higher crosslinking density.
Another important advantage of using PC7400 in silicone sealants is that extended tooling times can be achieved without jeopardizing crack-resistance.
