Values shown are typical for the current commercial grade. A lot-specific Certificate of Analysis accompanies every shipment; the grade-specific SDS is available on request.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Methyltris(methylethylketoxime)silane (CAS 22984-54-9) is an oxime-functional organosilane that releases methyl ethyl ketoxime as it cures with atmospheric moisture. It is used as a crosslinker and binder in neutral-cure (oxime) one-component silicone sealants, as an adhesion promoter and surface modifier, and as a waterproofing and sealant component.
Frequently Asked Questions
What is methyltris(methylethylketoxime)silane?
Methyltris(methylethylketoxime)silane (CAS 22984-54-9, C13H27N3O3Si) is an oxime-functional organosilane that releases methyl ethyl ketoxime as it cures with atmospheric moisture. It is supplied as a crosslinker and binder for neutral-cure silicone sealants and as an adhesion promoter.
What is methyltris(methylethylketoxime)silane used for?
It is used as the crosslinker in one-part neutral-cure (oxime) RTV silicone sealants, curing on exposure to atmospheric moisture, and as an adhesion promoter and barrier-sealant binder. It also functions as a waterproofing component and surface modifier in silicone systems.
Why is it called a neutral-cure or oxime crosslinker?
On contact with humidity it cures by releasing methyl ethyl ketoxime rather than acetic acid, so oxime-cure sealants are described as neutral-cure and are less corrosive to sensitive substrates than acetoxy systems. This makes it a common crosslinker choice for sealing metals, glass, and electronics enclosures.
What is the HS code for methyltris(methylethylketoxime)silane?
It is classified under HS heading 2931.90 (other organo-inorganic compounds). Confirm the destination-country tariff subheading with your customs broker.
How is methyltris(methylethylketoxime)silane supplied in bulk?
RawSource supplies oxime silane crosslinkers in bulk industrial packaging such as drums and totes/IBCs to silicone-sealant manufacturers. Because the material is moisture-sensitive it ships sealed; request a current SDS and CoA and submit a bulk quote for volume pricing, MOQ, and lead time.
