Features and Benefits

• Low cost, non-toxic, mild reducing agent.

• Due to its electrophilicity, it is an attractive hydride source for hydrogenation

silanization, dehydrogenation silanization and polymer formation reactions.

Application Fields

• Production of additive forming silicone rubber, silicone gel, methyl hydrosilicone oil and

other special additives.

• Can be used for the formation of reducing sulfide and the reduction etherification

reaction.

• A reaction agent for the synthesis of monofunctional siloxane derivatives by

hydrogenated silanization

• Reducing agent for the synthesis of halogenated hydrocarbons by aldehydes
