One-part high temperature silicone sealer which prevents dusting of fibrous insulation materials to 1100 oF (593 oC ). This advanced sealer is used in critical oven and furnace applications in the automotive, electronics and heat treating industries. Requires heat curing for 1 hour at 450 °F. Adequate ventilation is required. Outgassing will occur above 300 oF and cease after 750 oF. An additional 30 minutes is required at the highest service temperature if the service temperature is below 750 oF.
