Dynasylan® GLYMO
- CAS Number
- 2530-83-8
- Chemical Name
- Trimethoxy(3-glycidyloxypropyl)silane
- Chemical Family
- Organosilane
Dynasylan® GLYMO is a bifunctional organosilane, featuring a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. This dual reactivity empowers Dynasylan® GLYMO to chemically bond with both inorganic materials (e.g., glass, metals, fillers) and organic polymers (such as thermosets, thermoplastics, elastomers). It functions as an adhesion promoter, crosslinking agent, and surface modifier.
