CA-9™ Mastic

Polyguard’s CA-9 Mastic is an oil resistant, cold applied coating for use on buried steel substrates.  CA-9 is a single component bitumen coating that provides a high film building characteristics of up to 12 mils per coat.  The unique combination of solvent and resin found in CA-9 allows for application without the need for a primer/adhesive coating. It is an excellent coating for irregular shaped steel structures buried in  a corrosive environment. CA-9 provides enhanced resistance to crude oil an aliphatic petroleum products.

Features & Benefits

  • High solids content.
  • Low cost per mil durable coating for underground substances.
  • Excellent to deterioration from acids and alkalis encountered in normal soil.
  • Easily applied to irregular and complex shapes such as valves, flanges, tees, elbows and mechanical couplings.
  • Vinyl component enhances resistance of CA-9™ Mastic to most crude oil and aliphatic hydrocarbons.
  • No priming required.

 

Handling Materials:

Polyguard Mastics should be handled in such a manner as to prevent injury to the materials. All containers should be protected from weather and lids securely fastened. In cold weather, materials shall be stored in heated buildings and transported in warmed vehicles. Store above 60° F (16° C).

 

Surface Preparation:
Steel surfaces should be cleaned of all paint, oils, grease, mill scale, loose welding, residue, burrs, dust, dirt, frost, moisture, and other foreign matter. Where feasible and practical the surface can be blasted to a NACE No. 3 finish. Otherwise, hand wire brush cleaning method may be used providing all above foreign matter is removed. No priming is required.

 

Application:

Polyguard Mastics should be brush applied. They are normally applied in a two coat system. The first coat should be dry before the second coat is applied. Drying time is dependent upon the atmospheric and surface temperature. The coating should be done in areas free of dust and moisture.

 

Coverage Rate:

POLYGUARD CA-9 ™ Mastic covers approximately 60 square feet per gallon (1.48m2/liter) on smooth surfaces. The dry film thickness will be approximately 12 mils with a wet film thickness of 20 mils to obtain this coverage. Two coats are recommended.
