English description（英文原文，共 1314 字符）
Product Name:Hydroxy-terminated silicone oil
English Name:Hydroxy-terminated silicone oil
CAS No.:58130-04-4
Aliases:Hydroxy-terminated polydimethylsiloxane, Polydimethylsiloxane silanol, Silanol-terminated PDMS
Molecular Formula:(C2H6OSi)nC26H54O5Si2
Physical Properties:It is a colorless transparent viscous liquid with no odor. It has good solubility in organic solvents and, at low molecular weight, partial water solubility. The terminal hydroxyl groups enable condensation reactions with active functional compounds. It exhibits excellent high and low temperature resistance, electrical insulation, and chemical stability, and can participate in crosslinking or modification reactions.
Uses:It is mainly used as a reactive plasticizer and crosslinker in silicone sealants and adhesives to improve flexibility and adhesion. It also serves as a finishing agent for textiles, a leveling agent for coatings, and a fine chemical intermediate, providing hydrophobicity, lubricity, and weather resistance to surfaces.
Technical Specifications:
Appearance: colorless transparent viscous liquid
Viscosity (25°C): 50–1000 mPa·s, adjustable by grade
Hydroxyl content: 0.1–0.5% (by mass), corresponding to hydroxyl value of approx. 3–15 mg KOH/g
Density (25°C): 0.97–0.99 g/cm³
Flash point (open cup): ≥150°C
