Silicone Addition Clear 25 Fast(Medium Hard)
The Silicones A Crystal clear 25 is a 2-component (Platinum) Poly-addition silicone-molding which cures at room temperature. The silicones are, after mixing, good liquid and crystal clear.
Crystal clear silicone which are suitable for flexible infusion of LEDs and optical elements. These silicones are also very suitable for simulation of water in aquarium sets and windows in modeling.
Because of the low shrinkage and very good clarity are ideal for this silicone potting electronics, optical elements or as a mold for oermodellen without undercuts that need to be cut out.
This version is quicker than the normal one. It also suffers less from cure inhibition and is therefore more suited for use in less than ideal situations.

Note: Pot life / ontmaltijd is highly dependent on temperature! At a higher temperature, the processing time and ontmaltijd be shorter.
The Silicones A Bright, one can simply mix with the hand or by machine. Mix the A and B component carefully and in the indicated ratio (100 parts A and 100 parts B) together. Process the mixture in the pot life and wait ontmallen until it is cured complete. Alternatively, you can speed up the curing process by placing the whole in an oven. Make sure that air bubbles in which case shorter given the time to escape.
Trapping air bubbles can be prevented best by pulling the silicone vacuum immediately after mixing. To prevent air bubbles, stir the A and B component well but slowly without storing in air. The best create a "figure 8" motion. If you want to reduce the Shore (stiffness), then you can add silicone oil from the shop. If you do not want to pour the silicone spatula but you can add Silicone Thixo A (note: not Silicone Thixo C!!). You can also add fumed silica. You can silicone intense colors with silicon dye.
The silicon reach their final properties after post Curing / after-baking for 1 hour at 80 ° C.
