Phenyltris(butanoxime)silane

Phenyltris(butanoxime)silane (CAS 34036-80-1), also known as Phenyltris(methylethylketoximio)silane, is an oxime-functional silane crosslinker used in room-temperature vulcanizing (RTV) silicone systems.

It releases butanone oxime during cure, enabling moisture-triggered crosslinking without requiring elevated temperatures. In one-component RTV silicone sealants, it controls cure speed and network density.

This makes it a standard crosslinker for construction, glazing, and automotive sealing applications. Silicone adhesives for electronics and industrial assembly rely on it to achieve cohesive, flexible bonds.

The material provides good adhesion to glass, metal, and plastics. Formulators of silicone coatings use it to tune film hardness and surface properties in protective and release coating systems.

It also functions as a reactive modifier in silicone elastomer compounding, where it influences rheology during processing before final cure. This versatility is essential for high-performance industrial applications.

Phenyltris(butanoxime)silane is supplied as a liquid, typically in drums or IBC containers suited for industrial-scale sealant and adhesive manufacturing. It is available in technical grade for various uses.

Purity specifications are commonly confirmed by GC analysis to ensure consistent performance. Buyers should verify oxime content and moisture sensitivity controls when evaluating supply chain suitability.
