Characteristic and Usage:
SILONG 802 is a reactive siloxane with terminated Si-H bond. It can occur addition reaction with alkenes, so is utilized widely to prepare H-terminated polysiloxanes which is used as crosslinker or chain extender of LIM silicone rubber, to synthesize variety functional reactive silicone fluids which is used to form silicone block copolymer. SILONG 802 is also used as reductant in organic synthesis.

Physical properties:

Items Index
Appearance(APHA) ≤20
GC Purity(%) ≥98.0
Ionic chloride(ppm) ≤10

Packaging and Storage:
SILONG 802  is a highly volatile, inflammable and explosive dangerous compound, so is packed in steel cylinder. Because of its reactivity, it will be hydrolyzed by moisture to form polymer and release hydrogen. SILONG 802 should be hermetically storaged at low temperature, do not stored in direct sunlight, keep container closed and away from heat, sparks and open flames.
SILONG 802 can little stimulate skin and eyes, so it is necessary to dress appliances for labor protection when contacting it.
