What is Vinyltris(methylethylketoxime)silane?
Vinyltris(methylethylketoxime)silane (CAS 2224-33-1), also referenced as Vinyltris(methylethylketoximino)silane, is an oxime-functional silane crosslinker used in room-temperature-vulcanizing (RTV) silicone systems.
Where is Vinyltris(methylethylketoxime)silane used?
- Neutral-cure RTV-1 silicone sealants: crosslinker
- One-component silicone sealants and coatings: releases methylethylketoxime upon moisture exposure for controlled cure
- Construction and automotive glazing: adhesion to glass, metals and plastics without acetoxy acidity
- Electronics: conformal coatings and potting compounds for corrosion-sensitive substrates
- Silicone elastomer formulators use it to tune mechanical properties.
- Industrial gaskets and sealing profiles: cure speed adjustment
- Silicone-based adhesives: surface modifier improving substrate compatibility and bond durability
Commercial specifications
- Technical grade, purity typically 98% or above
- Packaging from drums to IBC containers
- Bulk supply for industrial formulators with consistent volume requirements
