PPG 44GN098 (1-USQT-KIT)

Additional Product Information

Overview

44GN098 is a chrome-free, water-reducible, chemically cured polyamide epoxy primer designed for high-performance corrosion protection in aviation and maintenance, repair, and overhaul (MRO) environments. This aerospace-grade primer is trusted for its excellent adhesion, chemical resistance, and long-term durability on treated aluminum and metal substrates. Aerospace and maintenance teams rely on it for its reliable protective barrier against hydraulic fluids, lubricants, and environmental moisture exposure.

Why 44GN098 Water Reducible High Performance Epoxy Primer is Chosen for AOG / MRO

• Rapid production support through fast drying and controlled overcoat windows.
• Chrome-free environmentally responsible formulation.
• Excellent adhesion and corrosion resistance for critical aircraft structures.
• Supports multiple spray application technologies.
• Reliable performance in fluid immersion and chemical exposure environments.

Practical Suggestions for Your Team (AOG Mindset)

• Condition coating components at 13°C – 35°C (55°F – 95°F) for 24 hours before mixing.
• Maintain constant agitation during spray application to prevent pigment settling.
• Target dry film thickness of 15 – 22.5 microns (0.6 – 0.9 mil).
• Limit mechanical mixing time to under 5 minutes to preserve coating stability.
• Stock touch-up kits for emergency maintenance and field repair operations.
