DOWSIL™ 3-6548 RTV Silicone Foam is a two-part, room-temperature vulcanizing (RTV) silicone foam that expands upon curing to form a soft, low-density, and resilient foam. It provides excellent sealing, cushioning, and insulation properties while offering resistance to environmental factors such as moisture, chemicals, and extreme temperatures. This material is commonly used in applications requiring lightweight, flexible, and durable protection.
