606 Filler Compound

POLYGUARD 606 FILLER COMPOUND is a fabric reinforced coating for molding irregular surfaces. 606 FILLER COMPOUND is a cold applied protective coating. Within the rubberized bitumen coating is a continuous filament thermoplastic fiber for reinforcement. The fiber adds tensile strength and provides resistance to tear. The continuous filament fiber used to reinforce the coating is randomly arranged and highly dispersed within the compound. The fiber can be stretched within its break level so as not to restrict conformability and to assure exceptionally good molding characteristics. The coating is supplied in rolls and utilizes both paper and plastic film release sheets which are removed prior to application.

Features & Benefits

  • Easily applied and provides excellent conformation and molding properties.
  • Has excellent resistance to water or vapor transmission.
  • Not subject to deterioration from below ground acids and alkalis that are encountered in normal soil.
  • Has excellent ability to resist infiltration of moisture.
  • Has elastomeric properties to accommodate normal expansion and contraction of the substrate.
  • Includes as the basic corrosion coating a polymer modified bitumen.


606 FILLER COMPOUND is designed for hand application. It is primarily designed for use over weld seams but also finds use as a filler material under the coating and wrapping of station piping, irregular shapes such as valve bodies, flange bolts, and compression fittings.


Handling Materials: 606 FILLER COMPOUND and LIQUID ADHESIVE should be hauled and stored in such a manner as to prevent injury to the packages. All packages and rolls of wrapping materials should be transported in warmed vehicles and stored in a warm dry place and kept from contact with earth and protected from weather at all times.
Although the 606 FILLER COMPOUND can be utilized at lower temperatures, to maximize the quality application characteristics it is recommended that the compound and liquid adhesive be maintained at a temperature of 60EF (16EC) or higher during application.


Surface Preparation: The pipe shall be cleaned of all paint, oil, grease, mill scale, loose rust, welding residue, knurls, frost, dust, moisture, weeds and other foreign matter. Applying Liquid Adhesive: Polyguard Liquid Adhesive should be applied at an average rate of 400 sq. ft. per gallon (10.0m2/liter). Stir before using. Apply with brush or roller to clean and dry substrate.
