Description

Bis(dimethylamino)dimethylsilane (Bis-DMAS) is a silylating agent that reacts with the hydroxy groups of siloxanes to form a cross-link. It can be used as a functional group for the synthesis of polymers, coatings, and adhesives. Bis-DMAS has also been used to improve the reactivity of other functional groups, such as carbonyls, amines, nitriles, and epoxides. It is reactive in air and moisture and should be stored in an inert atmosphere. Bis-DMAS reacts with metal surfaces to form a coating by reacting with both the metal surface and hydrogen atoms on the surface. The reaction temperature is dependent on the substrate: higher temperatures are needed for copper than aluminum due to copper's higher reactivity. The activation energies are different for each reaction type: thermal reactions have an activation energy of 40 kJ/mol while electrochemical reactions have an activation energy of
