Methyltris(methylethylketoxime)silane

Methyltris(methylethylketoxime)silane (CAS 22984-54-9) is an oxime-functional silane used as a crosslinker and curing agent in silicone-based systems. It releases methyl ethyl ketoxime upon moisture exposure.

This reaction enables room-temperature vulcanization without requiring heat or catalyst activation. Its primary use is in one-component (1K) RTV silicone sealants, where it controls cure speed and mechanical properties.

The chemical determines the final characteristics of the cured bead, which is critical for construction, glazing, and automotive assembly applications. In silicone adhesives, it functions as a crosslinker.

This crosslinking determines network density, directly affecting elongation and tensile strength in the finished product. Coatings formulators incorporate it into silicone release coatings and conformal coatings.

It is utilized where controlled surface cure and adhesion to substrates are required. Personal care applications include silicone-based formulations where surface modification of inorganic fillers is necessary.

Conditioning agents also require this reactive silane chemistry for effective performance. The product is supplied as a clear liquid in standard industrial packaging, including drums and IBCs.

It is available in technical grade, with purity specifications typically at 97% or higher depending on the supplier. Moisture-sensitive handling requirements influence the specific packaging specifications.

Buyers should confirm shelf life and storage conditions when evaluating supply options. This ensures the material maintains its reactive properties throughout the duration of its intended industrial use.
