ADVANTAGES:
- Excellent cathodic disbondment resistance.
- Uniform factory controlled thickness.
- Damaged coating areas can be repaired quickly and easily.
- Excellent resistance to water or vapor transmission.
- Resistant to deterioration from acids and alkalis encountered in normal soil.
- Excellent ability at the lap to resist infiltration of moisture.
- Elastomeric properties to accommodate normal expansion and contraction of the substrate.
- Easy to apply.
- Excellent peel adhesion.
Polyguard 600 Coating
POLYGUARD 600 SERIES COATING SYSTEMS
are laminated protective coatings. The primary corrosion coating material is a rubberized bitumen coating, bonded to a white polyethylene film. For products that conform easily, Polyguard coatings have exceptional adhesion and mechanical strength. The coatings are supplied in rolls for easy application on all sizes of pipe.
