Phenyl Tris Methylethyl Ketoxime Silane CAS 34036-80-1

1. Phenyl tris(methylethylketoxime)silane is a neutral oxime silane crosslinking agent primarily used in the manufacturing of one-part room-temperature-vulcanizing (RTV-1) silicone sealants to produce formulations with high elongation, low modulus, and improved tear resistance .
2. Phenyl tris methylethyl ketoxime silane serves as a crosslinker in sealant formulations where extended tooling time and crack resistance are required, and it also enhances the heat resistance of the final silicone products .
3. In advanced materials research, phenyl tris(methylethylketoxime)silane is applied as a precursor for OLED encapsulation layers, forming dense crosslinked networks with low water and oxygen permeability that protect light-emitting components and extend device lifetimes .
4. The compound is also utilized in the preparation of crosslinked thin films for hole transport layers and electron blocking layers in OLED devices, contributing to improved mechanical strength and thermal stability of the multilayer structures .

1. Phenyl tris(methylethylketoxime)silane must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at 2-8°C (refrigerated), as it is moisture-sensitive and readily hydrolyzes upon contact with water .
2. Phenyl tris methylethyl ketoxime silane is classified with GHS signal word "Warning" and hazard statements H302 (Harmful if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation), H317 (May cause an allergic skin reaction), and H335 (May cause respiratory irritation) .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep away from incompatible materials such as strong oxidizing agents, and store containers without contacting iron or steel to prevent corrosion; avoid release to the environment due to aquatic toxicity (H412) .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when phenyl tris(methylethylketoxime)silane is released .
2. For Phenyl tris methylethyl ketoxime silane liquid spills, contain and collect the product using inert absorbent materials such as sand, diatomite, or universal binders with non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating vapors or mists during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration with flue gas scrubbing .

1. Phenyl tris(methylethylketoxime)silane is a combustible liquid with a flash point of 61-106°C (closed cup), and may decompose under fire conditions .
2. Use dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray to extinguish fires involving the product; do NOT use a direct water jet as Phenyl tris methylethyl ketoxime silane may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning phenyl tris(methylethylketoxime)silane due to hazardous decomposition gases .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
