Applications
TOSIL-MTAS is transported from the production site as the parent silane to formulators. Generally, TOSIN-MTAS is used as a cross-linker at 3% to 5%.
As TOSIN-MTAS 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.
TOSIN-MTAS 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).
