- Cure Method
- Application Notes
- Skive – use closed skive construction
- Repair – Same.
- Cured Durometer – Shore A durometer of top surface: 85 ± 10.
- Special Treatment After Application - Brush the rubber surface with three (3) separate coats of C-600 activator. Allow to dry for 30 minutes between each coat.
- Curing
Cure time adjustments may be required to compensate for specific conditions. See Section 10 of the Application Manual for detailed instructions. All recommendations below are for lining thicknesses up to ¼”.
Ambient - The chemical cure lining will vulcanize in about three (3) weeks at 75°F/24°C.
Atmospheric Steam Assist – Introduce exhaust steam sufficient to insure contact with all surfaces. Approximately 8-12 hours in exhaust steam will be required to cure lining. More time may be necessary in a large tank, or if heat losses are large.

Safety & Health
- Precautions
- This is a hard rubber compound. Over curing will cause brittleness.
- Do not use in transport equipment. This lining may not be suitable for equipment that may be exposed to extremely low temperatures. If temperatures will be below 32°F/0°C.
- Cool down to 120°F/49°C before releasing pressure during pressure cure.
- Do not ship lined tank below 20°F.
Storage & Handling
- Storage
Store in a cool and dry area
Shelf Life Stored below 50°F (10°C) 180 days Stored between 51 and 70°F 90 days Stored between 71 and 90°F 45 days Do not store above 90°F (32°C) Depending on storage conditions it may be possible to use rubber linings beyond the recommended shelf life however additional testing must be completed.
Storage, handling and application methods must conform to the Polycorp Rubber Lining Application Manual.
