Q: Does silicone release PCBs during curing?


A: There is a possibility that certain compounds (usually those used for extrusion purposes) can evolve very low quantities of PCB''s.


These are derived from the peroxide used to cross-link the silicone. It is therefore wise to ensure that adequate ventilation and


extraction is provided in the areas where such compound is being processed.


Q: Can I thicken a silicone?


A: Silicone liquids can be thickened to a certain extent by the addition of silicas.
