ABchimie R12230 Optically Clear Encapsulation Gel
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Optically clear
- Quick setting
- Good heat stability
Product Description
ABchimie R12230 GEL is a pourable, two‑component silicone rubber that cures at room temperature through a polyaddition reaction to form a very soft, optically clear silicone gel. Designed for high‑transparency applications, it provides excellent protection for sensitive electronic components while maintaining exceptional clarity and long‑term stability.
Its softness, transparency, and ability to flow into complex geometries make R12230 GEL ideal for encapsulating sensors, delicate electronic assemblies, and components requiring vibration damping. A fast‑curing version, R12230 GEL ACC, is also available for applications requiring shorter processing times
Product Key Features
- Excellent transparency for optical or sensor‑based applications
- Easy‑flowing formulation suitable for potting complex shapes
- Provides vibration damping and mechanical stress relief
Applications
- Encapsulation of optical or light‑sensitive electronic components
- Damping systems and vibration‑sensitive assemblies

Mixing of the Two Components
Hand mixing
The two components are thoroughly mixed using an electrical or pneumatic mixer, on a low speed setting so as to limit the inclusion of air in the mixture. A dispensing machine can also be used. After mixing A and B parts, it is preferable to degas the product to eliminate the air bubbles that would be visible in the finished part and which would reduce the mechanical and dielectric properties. Degassing is generally carried out with a vacuum of 30 to 50 mbar releasing the vacuum several times during the operation. A recipient with a high diameter/height ratio is better suited to quick degassing; however the height must be sufficient to contain the swelling of the elastomer under vacuum conditions.
Automatic mixing (to be preferred when using R12230 GEL ACC as the pot life is too short to hand-mix and efficiently degas the material).
In order to avoid any air bubbles that may affect the mechanical and dielectric properties, it is recommended to degas separately A and B part, prior to pour it slowly and regularly into the tanks of the dosing machine. The A and B Parts should be dosed and mixed with a static mixer with a standard commercial equipment (A special care is recommended in pumping the product from the tanks to avoid any air entry before dosing and mixing).
After Mixing
R12230 GEL (A+B) or R12230 GEL ACC (A+B) is poured slowly and regularly. In the case of a high thickness coating operation, the casting must be made at the lowest point in the volume to be filled; this avoids forming and including air bubbles in the volume. It should not be filled totally to allow expansion of the gel at service temperatures. Certain materials that R12230 GEL or R12230 GEL ACC may be in contact with when curing could inhibit the reaction. Especially troublesome materials are: Sulphur- containing cured natural and synthetic rubber compounds (neoprene, latex, SBR), tin catalyzed silicone rubbers, amine catalyzed epoxies, PVC stabilized with tin salts and some polyurethane elastomers.
