Characteristics

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

Epoxy Silicone Oil synthesis Reference Process

1. 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.

2. If the catalyst is tetramethylammonium hydroxide solid, first put 1⁄3-1⁄4 DMC 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).
