Applications of LS-VIPS Vinyltriisopropenoxysilane
1. Neutral enoxy RTV silicone sealants
Used as crosslinking component in neutral de-acetone RTV silicone sealant systems. Verify skin-over time, through-cure, modulus, elongation, adhesion, and storage stability by formulation testing.
2. MEKO-free silicone sealant systems
Used in silicone sealant formulations where oxime-based crosslinkers are not preferred. Confirm MEKO-free or other regulatory compliance based on the complete formulation.
3. Electronic silicone coatings and potting systems
Used in moisture-curing silicone coatings and potting materials. Verify corrosion behavior, dielectric properties, cure profile, and compatibility with electronic components in the target system.
4. Moisture scavenging in silicone systems
Used as moisture-reactive component in anhydrous silicone formulations. Verify moisture control, viscosity stability, and shelf-life performance under customer packaging and storage conditions.
5. Silicone polymer modification
Used as reactive silane component for preparing enoxy-functional or moisture-curable silicone intermediates. Verify reaction conditions, by-product profile, and final polymer properties by synthesis testing.
Packaging of LS-VIPS Vinyltriisopropenoxysilane
In 20kg pail,190kg drum and 950kg IBC
Safety and Storage of LS-VIPS Vinyltriisopropenoxysilane
Store in a cool, dry, well-ventilated environment. Keep away from direct sunlight, heat, sparks, and open flames.
The isopropenoxy groups hydrolyze on contact with moisture; keep in tightly sealed original containers.
Classified as non-hazardous combustible substance for standard transport.
Shelf life: 24 months minimum from manufacture date when stored at ≤25°C in original tightly sealed unopened containers.
