Product Overview
Hydroxy Silicone Oil 10000cst CAS 70131-67-8 is medium-high viscosity hydroxyl-terminated polydimethylsiloxane, generally called 107 silicone rubber.This product owns active terminal hydroxyl groups, which can conduct polycondensation crosslinking reaction with acetoxy silane crosslinkers under catalyst. The cured sealant releases acetic acid small molecules, characterized by fast tack-free speed, outstanding transparency and great adhesion to glass. It is specially developed as core base polymer for one-component acetic silicone sealant.
Product Properties
Clear, colorless viscous liquidKinematic viscosity: 10000 mm²/s (25℃)Stable hydroxyl valueNarrow molecular weight distributionGood compatibility with fillers and acetoxy crosslinkersLow volatile matterEasy to adjust extrusion performanceStable performance under sealed storage
Core Advantages
- Stable viscosity, convenient for customers to adjust extrusion property of acetic glass glue
- Excellent dispersion effect with silica, calcium carbonate and other fillers
- Fast surface drying speed, improve production efficiency of sealant manufacturers
- High transparency after curing, ideal for decorative glass bonding
- Reliable adhesion on glass, ceramic and many inorganic substrates
- Low impurities, effectively extend storage life of single-component acetic sealant
Main Applications
10000cst Hydroxy Silicone Oil acts as Base Polymer for Acetic Silicone Sealant.Typical applications: base raw material for one-component acetoxy silicone glass sealant, decorative glass assembly adhesive, aquarium glass sealant, transparent building joint sealant, household glass bonding silicone sealant.
Usage Guidance
Keep away from moisture during storage and production to avoid premature crosslinking.Conduct small batch formula test to confirm the optimum proportion of crosslinker.The production workshop needs to maintain low humidity environment.Do not mix with acidic, alkaline substances and water-containing impurities.Tightly seal the container after use.
Packing & Storage
Standard package: 200kg iron drum; small test samples are available.Store in cool, dry and ventilated warehouse. Keep container tightly sealed. Stay away from open flame, high temperature, strong acid and strong alkali. Prevent water and impurity contamination during transportation.
