F-100 is a dimethylpolysiloxane fluid characterized by a high flash point and low surface tension. Compatible with both Platinum/Tin Base RTVs, it is used to thin viscosity and lower cured rubber hardness. With increased amounts of fluid, gel and cure times will be prolonged with a possible permanent gel state at 100% levels. *NOTE: Catalyst should be calculated at the amount of A-side (Base) only – prior to the addition of fluid.
