Triethoxyisobutylsilane CAS 17980-47-1

1. Triethoxyisobutylsilane is primarily used as a hydrophobic surface modifier and water repellent for construction materials such as concrete, cement, and masonry, where it penetrates deeply and chemically reacts to inhibit water absorption while maintaining substrate appearance .
2. Triethoxyisobutylsilane CAS 17980-47-1 serves as a silane coupling agent and adhesion promoter to improve compatibility between inorganic fillers (e.g., glass, silica, metals) and organic polymer matrices in coatings, adhesives, and sealants .
3. Triethoxyisobutylsilane is employed as a component in the manufacture of Ziegler-Natta catalysts for polypropylene production, acting as an electron donor to control polymer tacticity and molecular weight distribution .
4. In materials science research, triethoxyisobutylsilane is used as a dispersing agent, crosslinking agent, and surface modifier to generate hydrophobicity and increase compatibility with non-polar organic matrices .

1. Triethoxyisobutylsilane must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment under inert gas (nitrogen or argon), as Triethoxyisobutylsilane CAS 17980-47-1 is moisture-sensitive and undergoes hydrolysis upon contact with water .
2. Recommended storage conditions include temperatures below 15°C (room temperature in a cool, dark place) or at 2-8°C for long-term stability, with containers kept tightly closed to prevent moisture ingress .
3. Triethoxyisobutylsilane CAS 17980-47-1 is classified with GHS signal word "Warning" and hazard statements H315 (Causes skin irritation), H227 (Combustible liquid), and has a flash point of 60-63°C .
4. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and avoiding contact with skin and eyes .

1. Isolate the spill area immediately, ensure adequate ventilation, remove all sources of ignition, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable respiratory protection .
2. For Triethoxyisobutylsilane CAS 17980-47-1 spills, contain and collect the product using non-sparking tools and inert absorbent materials such as sand, diatomite, or universal binders, and place into suitable closed containers for disposal .
3. Avoid creating vapors or mists during cleanup to prevent respiratory exposure; prevent triethoxyisobutylsilane from entering drains or water courses due to potential environmental hazards (WGK Germany 3) .
4. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. Triethoxyisobutylsilane is a combustible liquid with a flash point of 60-63°C (closed cup) and may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and silicon oxides .
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 Triethoxyisobutylsilane CAS 17980-47-1 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 triethoxyisobutylsilane due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination and avoid release into waterways .
