- Usage
Duro-Bond Polypropylene is particularly resistant to attack by mineral acids including the oxidizing acids, such as nitric and sulfuric.. Duro-Bond Polypropylene can be bonded to various substrates. It-is used for lining plating tanks, acid etch tanks, pickling tanks, process vessels, neutralization tanks, drip pans, ventilation hoods and ducts.

- Repair Procedure
Duro-Bond Polypropylene sheet lining can be shop or field repaired. The repairs to defective or damaged areas in the sheet lining are accomplished by cutting out the faulty area, grinding or grit blasting the substrate surface, preparing a piece of sheet of the same dimension, cementing it into position and subsequently welding the joints as described under Application. The repaired area is then inspected and spark tested to insure lining integrity.
- Testing Methods
All lined surfaces are visually inspected for surface defects. Any special dimensional tolerances required after lining are also checked.. All lined areas are then spark tested for pinhole leaks using a dielectric spark tester adjusted to 10,000 volts. The tester is moved constantly and quickly over the lining surface to prevent a burn through.

- Service Temperature
The maximum continuous service temperature for which Duro-Bond Polypropylene can be used is 212°F (100°C). Corrosion resistant brick sheathing joined with one of the Electro Chemical corrosion resistant cements is used in conjunction with Duro-Bond Polypropylene when excessive temperatures are present. A 4" thick brick sheathing will provide a temperature drop of approximately 50°F and an 8" brick lining will provide a drop of approximately 100°F. When carbon brick are used the temperature drop will be somewhat less.
- Product Characteristic
Polypropylene is a thermoplastic resin that is melt flow processible. Duro-Bond Polypropylene sheet lining is available in thicknesses of 90 mils (2.3 mm) and 125 mils (3.0 mm).
