D3040 MAX COR CF HIGH SOLIDS PRIMER CONVERTER

What it is and why choose it

D3040 Max Cor CF High Solids Primer Converter is the converter component of Awlgrip Max Cor CF, a high solids, two-component, chromate-free epoxy primer designed for aluminum and steel surfaces above the waterline. Based on innovative Controlled Fusion (CF) technology, this system delivers excellent chemical and solvent resistance, strong anti-corrosive performance and outstanding adhesion without the need for sanding between coats within the specified overcoating window.

The CF technology creates a tightly fused intercoat layer between the primer and subsequent coatings, while eliminating the need for high hazard chemicals. When combined with the corresponding base component, Max Cor CF offers reliable protection for properly prepared steel and aluminum substrates in demanding marine and industrial environments.

Main features

• High solids, two-component epoxy system for steel and aluminum substrates.
• Chromate-free anti-corrosive primer providing protection above the waterline.
• Controlled Fusion (CF) technology allows extended recoat times and removes the need for sanding before applying the next coat (within the specified intervals).
• Excellent chemical and solvent resistance for long-term durability.

  • Alternatively, power-grind with 16–36 grit disc to obtain the required profile.
  • Surface must be clean, dry and free from dirt, grease and oil.
• Aluminum:
  • Sandblasted/ground to a 100% clean silver color.
  • Recommended surface profile: 2–3 mils (50–75 microns).
• Cleaning solvent: Awlgrip Wipe-Down Solvent (NA: Awlprep T0008 or Awlprep Plus T0115; AP: Awlprep Plus T0115; EU: Surface Cleaner T0340).

Applications and use cases

• Marine topsides and superstructures: Priming aluminum and steel surfaces above the waterline where corrosion resistance and strong adhesion are essential.
• Steel and aluminum components: Use as an anti-corrosive primer on properly prepared structural and fabricated parts that will be overcoated with compatible epoxy primers such as High Build or Hullgard Extra Epoxy Primer.
• Projects requiring extended recoat windows: Situations where Controlled Fusion technology and extended overcoating times reduce the need for sanding between coats, provided the maximum interval is not exceeded.

FAQ

1. What type of product is D3040 Max Cor CF High Solids Primer Converter?

   It is the converter component (OR3330) of the Max Cor CF high solids, two-component, chromate-free epoxy primer system for aluminum and steel.

2. Can Max Cor CF be used below the waterline?

   No. The product is specified for use above the waterline only.

3. Do I need to sand between coats of Max Cor CF?

   Within the specified overcoating intervals, Controlled Fusion technology removes the need for sanding before applying the next compatible coat.

4. What is the correct mixing ratio for the primer system?

   Mix 2 parts OR4330 base with 1 part OR3330 converter by volume, then mix thoroughly until homogeneous.

5. Should the product be thinned before spraying?

   No. The specification states “Do not thin/reduce.” Use the mixed product as supplied.

6. How should the steel surface be prepared before application?

   Grit blast to SSPC-SP10 (or Sa2½ outside the US) to a 2–3 mil (50–70 micron) profile, or power grind with 16–36 grit disc, ensuring the surface is clean, dry and free from dirt, grease and oil.

7. What is the pot life of the mixed primer?

   Approximately 2 hours at 25°C (77°F) and 50% relative humidity. At 35°C (95°F) pot life is about 60 minutes.

8. What happens if the maximum overcoating time is exceeded?

   The Max Cor CF layer must be fully removed and reapplied. If exceeding the interval is likely, apply Hullgard Extra to allow up to 6 months overcoating without sanding.

9. Which compatible primers can be applied over Max Cor CF?

   High Build and Hullgard Extra Epoxy Primer can be applied within the specified minimum and maximum overcoating times.

10. What are the recommended application temperatures?
