Dynasylan® MTMO
Dynasylan® MTMO is a bifunctional organosilane, featuring a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group. Its versatile reactivity enables chemical bonding to both inorganic materials (e.g., glass, metals, fillers) and organic polymers (such as thermosets, thermoplastics, elastomers). Serving as an adhesion promoter, crosslinking agent, surface modifier, or reactive reagent, Dynasylan® MTMO offers multifaceted functionality.

- Processing
Dynasylan® MTMO can be used as a primer (i.e. a ca. 0.5-10 wt.%. solution in an organic solvent such as alcohol), as an ingredient in a solution, or neat.. A chemical modification can be achieved by reaction of Dynasylan® MTMO with suitable functional monomers or polymers.
- Reactivity
In the presence of water, the methoxy groups of Dynasylan® MTMO hydrolyze and form reactive silanol groups which can bond to a variety of inorganic substrates.; The organophilic mercapto end of Dynasylan® MTMO can react with a suitable polymer.; Hydrolysis of Dynasylan® MTMO is catalyzed by acids.; Examples of suitable inorganic substrates are glass, glass fibers, silicia, quartz, sand, cristobalite, mica kaolin, talc, other silicate fillers and metals.; Dynasylan® MTMO may be used with such polymers as polyurethanes, polysulfides, sulfur-cured and metal oxide-cured elastomers.; Product modifications are possible by using Dynasylan® MTMO in addition or grafting reactions with suitable monomers or polymers (e.g. isocyanates, PVC etc.). An Si-O-Si crosslinking can take place via the silicon functional groups of the silane.
