AL2CHEM SPECIALTIES AL 170 Silane
- CAS Number
- 2530-85-0
- EC Number
- 219-785-8
- Chemical Name
- 3- (Trimethoxysilyl) propyl methacrylate

- Appearance
- Colorless transparent liquid
- Solubility
AL170 is soluble in methanol, ethanol, isopropanol, acetone, benzene, toluene, and xylene. After hydrolysis, it is soluble in water with adequate stirring if the pH is adjusted to 4.0. Hydrolysis releases methanol.. AL170 shows copolymerization or grafting reactions when catalyzed by (organic) initiator systems, e.g. peroxides or by radiation (e.g. UV).
- Soluble In
Ethanol, Isopropanol, Acetone, Toluene, Methanol, Xylene, Benzene, Water (after Hydrolysis)
- Applications
It is used as a coupling agent to improve the physical and electrical properties of glass-reinforced and mineral-filled thermosetting resins under exposure to heat and/or moisture.; It is typically employed as a blend additive in resin systems that cures via a free radical mechanism (e.g. polyester, acrylic) and in filled or reinforced thermoplastic polymers, including polyolefins and polyurethanes.; It is also used to functionalize resins via radical initiated processes - copolymerization or grafting - and to modify surfaces.
