Siwin-E563
(2,3-Epoxy propoxy)propylmethyldiethoxysilane
Description:
3-Glycidyloxypropylmethyldiethoxysilane is a colorless and transparent liquid at normal temperature and pressure. It is sensitive to acidic aqueous solutions and is soluble in common organic solvents. Because its chemical structure contains epoxy units, it is sensitive to strong acid and alkaline environments, and is prone to ring opening under acidic conditions, leading to deterioration. Therefore, contact with acidic substances should be avoided during storage and stored in a cool, dry environment
