Applications

Silane OSi HIOSil MTAC is an essential silane which

can be used in the below industry:

§ MTAC is transported from the production site as the parent silane to formulators.

§ Generally, MTAC is used as a cross-linker at 3% to 5%. As MTAC is compounded into a consumer or industrial sealant or adhesive, it reacts with the silicone. After curing the parent silane becomes cross-linked into the silicone rubber matrix and no longer exists, this greatly reduces the potential for consumer or worker exposure.

§ MTAC is often the main crosslinker of choice for silicone sealants and can be used by itself or in combination with other acetoxysilane to provide the sealant with targeted properties (such as desired cure rate, adhesion, etc).
