Epoxy silicone oil chain extender IOTA 105-1000

This product code is IOTA 105-1000. The product function is mainly used as one-step synthesis raw material of different molecular weight epoxy silicone oil. The direct synthesis method has solvent-free, light color, crystal clear, simple process, convenient use and good reproducibility. And many other advantages.

Product introduction and application:

1, Appearance: light yellow transparent liquid

2, Molecular weight: M = 1000

3, Structural formula:

4, Characteristics:

Synthetic silicone oil does not require solvent, light color, crystal clear, simple process, convenient use and good reproducibility.

5. Epoxy silicone oil synthesis reference process:

a. Put D4, chain extender and catalyst alkali glue in the reaction vessel (the amount of catalyst is 0.6~1‰ of the total amount of synthesis), heat up to 105～110°C, keep warm for 3~3.5 hours, then raise the temperature to 140～150°C. , heat for 1 hour, and vacuum off at 140 ~ 150 ° C for 30 minutes, cooling, discharging.

b. If the catalyst is tetramethylammonium hydroxide solid, first put 1⁄3-1⁄4DMC and the total amount of catalyst (0.6~1‰), and then vacuum to 75-80 °C while heating, continue dehydration for half an hour until dehydration is completed, add The remaining DMC and IOTA 105-1000, then warmed to 105 ~ 110 ° C, heat for 3 ~ 3.5 hours, then warmed to 140 ~ 150 ° C, heat for 1 hour, and vacuum at 140 ~ 150 ° C for 30 minutes, cooling , discharge (from 3% to 5% of the total amount of monomer, not off).

6, Reference feeding ratio:
