Autoclave 2 hours at 275°F (135°C)
Internal Pressure 6 hours at 260°F (127°C)
Atmospheric
Step 1
Observe a gradual warm-up time until reaching 160°F (71°C)Step 2
24 hours at 180°F (82°C) or
20 hours at 200°F (94°C)Note: Cure times may require adjustment to compensate for heavy metal thickness, low exterior temperatures or other unusual factors.
- Applicator Notes
- Neoprene may shrink 10% lengthwise after unrolling. Preshrink rubber before application.
- The temperature of the substrate must be greater than 60°F (15°C) prior to applying primer and rubber. Temperatures should not exceed 120°F (49°C).
- A heated table that warms rubber to approximately 120°F (49°C) prior to application is recommended.
- Strict adherence to adhesive specifications is required. Tack time is critical to the success of the bond.
- Plying up layers of rubber lining thicker than 1/4” could result in rubber flow or sagging during cure.
