CA-9™ Mastic

POLYGUARD CA-9™ MASTIC is a cold-applied, solvent release, corrosion resistant protective coating for waterproofing underground metal surfaces. This single component bitumen coating has high film building characteristics and provides dry film thickness up to 12 mils per coat. The solvent-resin combination obtains good substrate wetting, consequently a primer is not required for CA-9™ MASTIC.

CA-9™ MASTIC is an oil resistant solution of coal tar and vinyl resin. The combination of the tar and the vinyl provides
enhanced resistance to crude oil and aliphatic petroleum products.


CA-9™ MASTIC is recommended where a corrosive environment is encountered, including crude oil saturated soil. It is used
for below ground corrosion protection of pipe, tanks, valves, mechanical couplings and other irregular shaped steel structures.

400 WRAP is used to reinforce and protect Polyguard Mastics.


Here are some advantages of POLYGUARD MASTICS and 400 WRAP:

• High solids content.
• Low cost per mil durable coating for underground substances.
• Excellent resistance to water and moisture vapor transmission.
• Resistant 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 the resistance of CA-9™ MASTIC to most crude oil and aliphatic hydrocarbons.
• No priming required.
• 400 WRAP is not affected by the solvents or solids of the mastic. It provides excellent reinforcement and mechanical exterior
protection for the mastic, as well as a good platform for a second coat of mastic.
• 400 WRAP causes no irritation in handling. The fiber does not float off in the air during unwind and does not cause skin
irritation or inhalation irritations.


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 atmospheric and surface temperature.
Coating should be done in areas free of dust and moisture.
