【 Standard】
GB/T 20435-2006
【 Application】
It’s a basic raw material of silicone oil (modified silicone oil),silicone emulsion,silicone rubber ,silicone
resin and other silicone products, and can also be directly used as rubber filler treatment agents
or raw material for cosmetics.
【 Precautions】
The mixture of vapor and air is explosive. It’s easy to form explosive mixtures when fine dispersion
composition in the air .Static electricity will be accumulated and may ignite vapors. Prevent a possible fire
hazard by bonding and grounding or using inert
gas purge. Keep container closed and away from heat, sparks, and flame.
【 Package storage and transportation】
1、 Packing:200L iron drum(N.W.190 ㎏/drum） ； IBC （ N.W. 950 kg）
2、 Transportation:Keep container closed and away from heat, sparks, flame and the direct sunlight, acid and alkali
3、 Storage:Stored at 20℃ ～40℃ warehouse, pls do the antifreeze preparations when the temperature is below 17 ℃.
4、 Shelf time:6 months.Beyond the time ,it can still be used after re-test,if the test result meets the requirement of this standard.
