DOWSIL 3-8159 RF also known as Dow Corning 3-8159 RF is a two-part, room temperature curing silicone foam system.
Applications: - DC 3-8159 RF Silicone Foam is designed to be dispensed and cured directly on parts to form an integrated compression gasket.
- Typical applications include automotive parts (e.g. front and rear light units) and domestic appliance components (e.g. dishwashers).
