Structural Formula

Physical Indicators

CAS: 24801-88-5 Appearance: Colorless to light yellow transparent liquid Boiling point: 283 ℃/760mmHg Flash point (closed cup): 77 ℃ Density (20 ℃): 0.999g/cm3 Refractive index (nD25): 1.421 Solubility: Soluble in solvents such as acetone, ether, toluene, and reacts with solvents containing active hydrogen such as alcohol and water.

Use

1. A silane coupling agent containing active isocyanate functional groups. The isocyanate group exhibits the typical chemical properties of alkyl isocyanate, which can easily react with active hydrogen (such as hydroxyl, amino, thiol, etc.) in organic polymers. After hydrolysis of the alkoxy group, it provides good adhesion to the substrate or crosslinks with each other; 2. It can be used as a crosslinking agent in single component moisture cured polyurethane to block the ends of binary alcohols or polyether polyols; 3. Adhesion promoter for single component moisture cured polyurethane or two component reactive polyurethane. 4. Organic silicone adhesive or coating adhesion promoter to enhance its adhesion, water resistance, and weather resistance; 5. Key materials for the production of STPU using organosilicon modified hydroxy polyethers.
