SEMICOSIL® 928 F
SEMICOSIL® 928 F is a pourable, thermally curable, addition-curing, one-part fluoro silicone rubber that cures to a soft silicone gel.
- one-part, ready-to-use
- thixotropic behavior
- rapid heat cure
- very low hardness (gel)
- outstanding resistance to chemicals
Embedding of electronic components in contact with oils, fuels and solvents.
All surfaces must be clean and free of contaminants that will inhibit the cure of the product. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds. If a substrate’s ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.
Please homogenize product before use.
Because of the thixotropy (shear thinning effect) the product can be dispensed easily with all dispensing equipments.
To eliminate any air introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended.
The product works best when cured at 100 °C or more depending on the size and heat sink properties of the components.
Temperature Curing time, thickness 10 mm
100°C 4 h
130°C 60 min
150 °C 30 min
We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions are given in our leaflet "Wacker RTV-2 Silicone Rubber - Processing".
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons. Please store at 2°C - 8 °C
