What is Methyltris(methylethylketoxime)silane?
An oxime-functional silane (CAS 22984-54-9) used as a crosslinker and curing agent in silicone-based systems.
Where is Methyltris(methylethylketoxime)silane used?
- One-component RTV silicone sealants: controls cure speed and mechanical properties
- Silicone adhesives: crosslinker that determines network density, elongation and tensile strength
- Silicone release coatings and conformal coatings: controlled surface cure and adhesion to substrates
- Personal care: surface modification of inorganic fillers and conditioning agents
- Upon moisture exposure it releases methyl ethyl ketoxime, enabling room-temperature vulcanization without heat or catalyst activation.
Good to know: Moisture-sensitive handling requirements influence packaging specifications. Buyers should confirm shelf life and storage conditions.
Commercial specifications
- Purity typically 97% or higher
- Drums and IBCs
