Characteristic and Usage:
SILONG 803 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 modified copolymer, typical is polyethertrisiloxane surfacant used in pesticides.

Packaging and Storage:
SILONG 803 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 803 can little stimulate skin and eyes, so it is necessary to dress appliances for labor protection when contacting it.
