Dowsil 3-6548 RTV Silicone Foam consists of two liquid components; A and B. When both components are mixed thoroughly in a 1:1 ratio by weight or volume, the product will expand and cure to a formed elastomer at room temperature.
Dowsil 3-6548 RTV Silicone Foam prevents smoke and gas penetrating through seals and forms to complex, irregular shapes.
The foam is resistant to temperature extremes, ozone, and UV radiation.
