Dynasylan® DAMO-T
- CAS Number
- 1760-24-3
- Chemical Name
- 3- (2- Aminoethylamino) propyl] trimethoxysilane
- Chemical Family
- Organosilane
Dynasylan® DAMO-T is a bifunctional organosilane, equipped with two reactive amino groups and hydrolyzable inorganic methoxysilyl groups. With this dual reactivity, Dynasylan® DAMO-T can establish chemical bonds with both inorganic materials (such as glass, metals, fillers) and organic polymers (including thermosets, thermoplastics, elastomers). This makes it an effective adhesion promoter and surface modifier.

- Processing
For substrate pretreatments (e.g. as a primer) Dynasylan® DAMO-T may be used as an approximately 0.5-2 wt.-% solution in an organic solvent such as alcohol, as a constituent of aqueous sizes or solutions, neat, or added to the polymer as an additive (at higher concentration: 1-10 wt.-%).
- Reactivity
In the presence of water the methoxy groups of Dynasylan® DAMO-T hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates.; The organophilic diamino group of Dynasylan® DAMO-T can react with a suitable polymer.; The hydrolysis of Dynasylan® DAMO-T takes place autocatalytically.; The pH value of the hydrolysate is about 10- 11.; For a longer stability of the hydrolysate a pH of 4 is recommended.; Examples of suitable inorganic substrates are glass or glass fibers.; Dynasylan® DAMO-T may be used with such polymers as phenolic, furan resins, PA, PBT, PC, EVA, modified PP, PVAC, PVC, acrylates and silicones.; Dynasylan® DAMO-T can undergo reactions with ketone or ester solvents.; The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates and/or carbamates.
