Series 431
Perma-Shield PL
Generic Type
Modified Polyamine Ceramic Epoxy
Common Usage
A 100% solids, abrasion-resistant lining specifically designed for wastewater immersion and fume environments and exposure to corrosive soils. Provides low permeation to H2S gas, protects against MIC and provides chemical resistance to steel, ductile iron pipe and fittings for severe wastewater or buried exposures. A coal-tar free, resin-rich formulation with low pigment volume concentration (PVC) for maximum performance.
Special Qualifications
Contains 20% ceramic microspheres for increased abrasion resistance. Compatible with high-velocity jet sewer cleaning (hydrocleaning) with 0-degree tips (Reference Technical Bulletin No. 11-86).
Meets the performance requirements of AWWA C 210 (not for potable water contact).

Recommended DFT
Carbon Steel: 30.0 to 50.0 mils (760 to 1270 microns) in one or more coats.
Ductile Iron: 40 mils (1015 microns) (nominal) in one or more coats.
Note: Number of coats and thickness requirements will vary with substrate, application method and exposure. Use Series 44-721 to increase film build. Amounts vary by kit size, refer to the Series 44-721 product data sheet. Contact your Tnemec representative for more information.
Curing Time
| Temperature | Set to Touch | Max. Recoat | To Place in Service |
|---|---|---|---|
| 90°F (32°C) | 1-2 hours | 7 days | 24 hours |
| 75°F (24°C) | 2-3 hours | 7 days | 2 days |
| 55°F (13°C) | 8-9 hours | 7 days | 3 days |
Note: If more than 7 days have elapsed between coats, the Series 431 coated surface must be mechanically abraded (scarified) before topcoating. Curing time will vary with surface temperature, air movement, humidity and film thickness.
Volume Solids
