OS 2000 Vinyl tris silane 2224-33-1 Honeywell Crosslinking / Coupling / Curing Agents >> Silane Silicones (Si) SEALANT ADHESIVE Vinyl tris(MEKO)silane. cross-linker in the production of 1-part neutral cure silicone sealants OS-2000 is clear and almost colorless fluid with a typical smell (MEKO). The product readily hydrolyzes upon contact with moisture. The product is used as a crosslinker in the manufacturing of 1-part neutral cure silicone sealant. OS-2000 is typically used in combination with OS-1000 to fine-tune the cure-profile of the sealant in order to provide crack resistant properties. Sealant-formulations containing only OS-2000 as the crosslinker can cure relatively well without Sn-catalyst. Hence OS-2000 is also used in sealant applications where the use of tin is to be avoided. Vinyl tris (MEKO) silane. Used as a crosslinker in the manufacturing of adhesives and 1-part neutral cure silicone sealants. Used where the use of tin is to be avoided. Provides crack resistant properties when used with methyl tris silane.
