Characteristic and Usage:
SILONG 812 is a reactive siloxane with NH2-terminated. It widely is utilized to synthesize variety viscosity amino-terminated polydimethylsiloxane which is used for polymer modification such as polyurethane, epoxy resin, polyamide, polyimide etc., also used for preparation of textile softners.

Packaging and Storage:
SILONG 812 is a nonflammable liquid but with slight corrosive. Because of its amino reactivity, it will absorb CO2 in air or is oxidized yellowing by O2 in air, so it should be tightly storaged at room temperature.
SILONG 812 can little stimulate skin and eyes, so it is necessary to dress appliances for labor protection when contacting it.
