DOWSIL 3-8259 RF also known as Dow Corning 3-8259 RF is a two-part, room temperature curing silicone foam system.

Applications: 

• DC 3-8259 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).

Typical Properties:

• Appearance:     

    Part A: grey
    Part B: translucent

• Viscosity (mPa.s):  

    Part A 35,000 - 75,000 
    Part B 20,000 - 70,000

• Specific gravity at 23°C: 

    Part A 1,10
    Part B 0,99

After mixing:

• Snap Time (sec): 2:40-3:40
• Tack-free time (min): maximum 10
• Flow (cm): maximum 20

Physical properties cured at 23°C and tested after 24 hours: 

• Density (kg/m³): 300-360
• Hardness, Shore 00: 65-70
• Compression set 50% compression:

    22 hours at 70°C non-post-cured: 16%
    22 hours at 70°C post-cured (1h at 100°C): 5%  
    Stress-strain characteristics in compression (kPa): 150
