Post by: gumusonur on September 11, 2018, 07:00:33 AM

Hi,

i wanna make silicone and oil mix. but it must be in gel consistency.
how can I make this? what can i use for consistency?

Thanks..

Depends exactly what you are using, have you tried to remove excess water to make it harder?

Hi,

one method is known to make extremely soft silicone rubber, which can be as soft as a gel: use silicone oil instead of silicone "resin", and cross-link it using the usual "hardener".

Silicone oils exist in varied molecular length that result in varied viscosity. You can also mix a silicone oil with a "resin" in varied proportion to adjust the hardness of the cross-linked rubber.

Is that what you're looking for?

thanks for help.

i find a product. Cyclopentasiloxan and Dimethiconol mixin. this is the product I'm looking for.

If I get it properly, cyclopentasiloxane would not be cross-linked when hardening the dimethylsiloxane (depending on the chosen hardener), resulting in a gel composed only of siloxanes. Well done.

Check for regulations in the EU for cyclopentasiloxane

If you only wish a very soft material, keep an eye on the suggested cross-linked silicone oil.
