Characteristic and Usage:
SILONG 804 is a reactive siloxane with Si-H bond. It can occur addition reaction with unsaturated alkenes, so it’s utilized widely to synthesize variety functional reactive silicone fluids which is used to form silicone block copolymer, or used as crosslinker of vinyl addition silicone rubber. SILONG 804 also is a importance precursor which is a silicon source liquid engineered for PECVD processes used to deposit thin film dielectrics.

Physical properties:

Items Index
Appearance(APHA) ≤20
GC Purity(%) ≥99.0
Ionic chloride(ppm) ≤10

Packaging and Storage:
SILONG 804 is a volatile, inflammable and explosive dangerous compound, so should be hermetically storaged, do not stored in direct sunlight, keep container closed and away from heat, sparks and open flames. Because of its reactivity, it will be hydrolyzed by moisture to form polymer and release hydrogen.
SILONG 804 can little stimulate skin and eyes, so it is necessary to dress appliances for labor protection when contacting it.
