Dynasylan® VTMOEO

Dynasylan® VTMOEO is a bifunctional organosilane possessing a reactive vinyl group and a hydrolyzable 2-methoxy-ethoxy-silyl group.

Typical Applications

1. Adhesion promotion
Dynasylan® VTMOEO acts as an adhesion promoter for various mineral-filled polymers improving their mechanical and electrical properties, especially after exposure to moisture.
Once bonded to an inorganic filler, Dynasylan® VTMOEO hydrophobises the filler surface. This effect improves the compatibility of fillers with the polymer matrix, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.
2. Dynasylan® VTMOEO as co-monomer for polymer dispersions
Polymer dispersions (e.g. styrene acrylics), modified with Dynasylan® VTMOEO show improved adhesion strenghth in wet conditions and wet scrub resistance.
3. Other applications
Dynasylan® VTMOEO can also be used as additive in organic coatings to improve adhesion on inorganic surfaces (metals, glass, ceramic surfaces), as well as for surface treatment of inorganic pigments.

Benefits at a glance

In the presence of moisture, the methoxy-ethoxy groups of Dynasylan® VTMOEO hydrolyze to produce 2-methoxyethanol and reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates. The vinyl functional end of Dynasylan® VTMOEO can react with a suitable polymer (activated by peroxide or radiation).
