Dynasylan® DAMO

Dynasylan® DAMO is a colourless to slightly yellowish liquid with an amine-like odour which is soluble in alcohols and aliphatic as well as aromatic hydrocarbons. 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.).
