Cure Time and Temperature:
Cure for thickness up to ¼”
| Pressure, Saturated Steam (Autoclave) | 2 hrs. @ 275°F(135°C) |
| Internal Steam Cure | 6 hrs. @ (20 psi) 260°F (126°C) |
| Atmosphere Steam Cure | Gradually warm until reaching 160°F (71°C) and then increase to 190°F-205°F (87°C-96°C) for 24 hrs. |
Note: All reference to cure psi represents gauge pressure.
**Cure times may require tunings to compensate for low temperatures, heavy metal thicknesses, and other anomalies. Contact SRR Technical Department for recommendations on lining thicknesses over ¼”.
Storage
Ideal storage temperature is 50°F not to exceed 85°F and shelf life is 180 to 45 day range respectively.
Depending on storage conditions it may be possible to use rubber linings beyond shelf life. Please contact Salem-Republic Rubber Company for technical advisement before usage.

Application Suggestions
- Lining should be uniformly preheated to 120°F prior to applying for ease of installation, pre-shrinking, and eliminating possible bloom.
- For gauges greater than ¼” plying up to desired thickness is recommended using a 45°/135° butt splice with offset seams on all but the top layer.
- It is recommended that lining layers adhere to each other using SRCE962CR.
- Experienced applicators may have techniques which produce equal or superior results and by no means are SRR’s application suggestions meant to replace these proven techniques. As long as those procedures fall within industry standard lining application guidelines.
