Applications of LS-AT402 Ethyltriacetoxysilane
1. Acetoxy-cure RTV silicone sealants
Used as crosslinking component in one-component acetoxy-cure RTV silicone sealants including sanitary, window, glazing, and general-purpose construction systems. Verify skin-over time, through-cure, modulus, elongation, adhesion, and storage stability in the target formulation.
2. Acetoxy crosslinker blends
Blended with methyltriacetoxysilane or other acetoxy silanes to adjust liquid handling, crystallization tendency, viscosity, and processing behavior. Determine blend ratio per storage temperature, production conditions, and sealant performance requirements.
3. Liquid crosslinker systems
Used where a liquid acetoxy silane component is required for storage, pumping, or dosing convenience. Verify compatibility with fillers, plasticizers, catalysts, and base polymers before scale-up.
4. Silicone elastomer formulation adjustment
Used as co-crosslinker in silicone elastomer formulations. Verify cure speed, by-product profile, mechanical properties, and aging behavior in the final system.
5. Acetoxy-functional intermediate use
Used as acetoxy-functional silane intermediate in synthesis or formulation development work. Verify reaction conditions, by-products, and final structure by analytical testing.
Packing of LS-AT402 Ethyltriacetoxysilane
In 25kg pail, 200kg drum and 1000kg IBC.
Safety and Storage of LS-AT402 Ethyltriacetoxysilane
Store in a cool, dry, well-ventilated environment. Keep away from direct sunlight, heat, and open flames.
Hydrolysis releases acetic acid; corrosive to acid-sensitive metals and substrates. Assess VOC and workplace exposure per local regulations.
Keep in tightly sealed original containers; moisture contact causes premature hydrolysis.
Shelf life: 12 months minimum from manufacture date when stored at ≤25°C in original tightly sealed unopened containers.
