Generic Type Epoxy mastic

Description

Aluminum pigmented, low-stress, high-solids mastic with a proven field history. This unique
formulation incorporates lamellar aluminum pigment for superior barrier protection. Carbomastic
15 was the pioneer mastic coating in a number of industrial markets and today still provides
unmatched levels of barrier protection and corrosion resistance over existing finishes and rusted or
SSPC-SP2 or SP3-cleaned steel.

Features

• Unique formulation with lamellar aluminum flakes for exceptional barrier protection
• Excellent performance over minimal surface preparation of steel substrates
• Suitable as a topcoat for most tightly adhered existing coatings
• Excellent choice for field touch-up of zinc-rich primers and galvanized steel
• Available in a low temperature cure version (Carbomastic 15 FC)
• Suitable for use under insulation on hot surfaces operating up to 300 °F (150 °C)
• VOC compliant to current AIM regulations

Color
Aluminum (C901); Red (M500)
Color variations within a batch and from batch to batch may occur due to the metallic pigments
and variations in application techniques and conditions. *Red (M500) is available for use as a
contrasting primer in multiple coat applications, but should always be topcoated.
Primer Self-priming. May be applied over most tightly adhering coatings as well as inorganic zinc primers.

Dry Film Thickness

3 – 5 mils (76 – 127 microns) over existing coatings
7 – 10 mils (178 – 254 microns) in one or two coats in severe exposures
Do not exceed 10.0 mils (250 microns) in a single coat.

Severe Exposures

Temperature resistance under insulation: Up to 300°F(150°C)
Discoloration is observed above 180°F(82°C) but does not affect performance.
