7001 PenPrime

Applications

The 7001 PenPrime is suitable for:

• Polyurea Applications: Primer for all polyurea coatings.
• Concrete Floors: Primer prior to epoxy or urethane floor coatings.
• Metal Surfaces:
  • Tanks, vessels, and structural steel.
  • EPDM roofing for polyurea applications.
• Cold Environments: Ideal for expansion joints, airfields, and industrial settings.

Advantages

• Compatible with ASTC’s Crystal Matrix Waterproofing (CMW).
• Works on a variety of substrates, providing a strong cross-link with polyurea coatings.
• Accelerated set time available with an optional accelerator.
• Semi-flexible with excellent impact resistance.
• Effective in protecting concrete and steel from corrosion.

Coverage

• Dry film thickness: 2–3 mils per coat; heavier applications up to 8 mils for specific needs.

Preparation

1. Concrete Surfaces:
   • Ensure a 28-day cure before application.
   • Remove curing agents, oils, wax, and other contaminants.
   • Perform a moisture vapor test before application.
   • Clean surfaces using an abrasive “brush-off” blast to provide a rough profile (minimum 2 mils).
   • Seal/repair cracks, spalls, and voids with ASTC-approved products (e.g., 830, 4034, 3004).
2. Metal Surfaces:
   • Round off sharp edges and remove burrs, weld splatter, and rough welds.
   • Clean thoroughly to eliminate contaminants.
   • Achieve a 2-mil profile through sanding, grinding, or sandblasting.
   • Use SSPC-SP standards for surface preparation:
     • Severe Exposure: SSPC-SP-5 Near-White sandblasting.
     • Mild Exposure: SSPC-SP10/NACE Near-White blast cleaning.

Curing Time and Temperature

• Set Time: 45 minutes to 1.5 hours.
• Cure Time: 2 hours at 70°F (environmental temperature affects curing).
• Application Temperature Range: 35°F to 125°F.
• Post-Application:
  • Allow the product solvent to “flash” before applying the topcoat.
  • If fully cured, sand/abrade the surface to create a profile before recoating.

Limitations

• Not for Wet Surfaces: Ensure all surfaces are clean and dry.
• Storage: Store at room temperature on wood pallets, away from direct sunlight.
• Environmental Conditions: Set time may vary with temperature and humidity.

Color

• Clear, honey-colored.

Health and Safety

• For professional applicators only.
• Wear protective clothing, goggles, and a NIOSH-approved mask.
• Use positive air supply in confined spaces.
• Read the Material Safety Data Sheet (MSDS) before application.
