Features & Benefits

- Materials Features
- Reactivity
- Dynasylan® DAMO is a bifunctional organic compound in which the silicon-functional methoxy-groups hydrolyze in the presence of water to form reactive silanols, which can be bonded to an inorganic substrate; the organophilic diamino group can interact with a suitable polymer.
- The hydrolysis of Dynasylan® DAMO takes place autocatalytically.
- The pH of the hydrolysate is about 10-11. For longer stability of the hydolysale a pH of 4 is recommended.
- Examples of particularly suitable inorganic substrates are glass or glass fibres.
- Examples of suitable polymers are PA, PBT, PC, EVA, modified PP, PVAC, PVC, acrylates and silicones.
- Dynasylan® DAMO can undergo reactions with ketones or esters as solvents.
- The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates resp. carbamates.
- Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds (for example isocyanates, epoxides, etc.).

- Processing
- For substrate pretreatments, for example as a primer (as an approximately 0.5-10 percent solution).
- Dynasylan® DAMO can advantageously be employed in organic solvents, such as alcohols and constituent of aqueous sizes or solutions.
- It may also be used as a pure substance or added to the polymer as an additive.
