AkzoNobel 0651-THINNER (5-Ltr-Can)

Pyroflex® 7 D 713 Conductive Polyurethane Primer

Overview

Pyroflex® 7 D 713 is a three-component conductive polyurethane primer developed by AkzoNobel Aerospace Coatings for non-conductive aerospace substrates such as composite structures. Designed to provide a durable conductive coating with excellent resistance to aircraft fluids and chemicals, it delivers a matt black finish with a surface resistance of less than 50 k?. The primer is widely approved by major aerospace OEMs and is suitable for aircraft manufacturing, composite structures and MRO operations.

Application Guidelines

• Remove mould release agents and degrease using approved cleaning solvents.
• Recondition aged primer using very fine Scotch-Brite® before recoating.
• Mix thoroughly before adding Hardener 0651.
• Allow a 15-minute induction period after mixing.
• Spray one full coat followed by a cross-coat after a 5-15 minute flash-off.
• Apply using conventional or HVLP spray equipment with a 1.4-1.8 mm nozzle.
• Clean equipment using Solvent Cleaning C 28/15 or Solvent Cleaning 98068.

Compatibility & Limitations

• Designed for composite and other non-conductive aerospace substrates.
• Must be applied over properly prepared surfaces.
• Observe primer recoat windows before applying subsequent coatings.
• If the 72-hour recoat limit is exceeded, abrade the surface before recoating.
• Application outside the recommended environmental conditions should be validated with AkzoNobel.
